Product Parameters

Key Components

Every jib crane—whether wall-mounted, floor-mounted, or mobile—is made up of several key components that work together to provide safe, efficient lifting and precise material handling. Each part of the crane is engineered to balance strength, flexibility, and ease of maintenance. Understanding the function and design of each component helps operators choose the right configuration for their workspace, ensure reliable performance, and maintain long-term safety. Below is a detailed look at the main components that make up a 3-ton jib crane system.

1. Boom and Pivot Assembly

The boom is the main horizontal arm of the crane. It carries the hoist and supports the load during lifting and travel. For a 3-ton jib crane, the boom is typically made from high-strength welded steel, often shaped as an I-beam or a box-section girder. These profiles are designed to minimize deflection and vibration under full load, ensuring stable and predictable movement.

• Structural Design: The boom is precision-welded and stress-relieved to prevent bending or warping under load. The I-beam design offers an excellent strength-to-weight ratio, while box-section designs provide greater torsional rigidity for longer spans.
• Surface Treatment:To prevent corrosion, the boom is usually sandblasted and finished with industrial-grade paint or powder coating. In harsh environments—like coastal areas or chemical plants—galvanized or epoxy-coated finishes are used.
• Pivot Assembly: The boom rotates around a heavy-duty pivot bearing located at the top of the mast or wall bracket. This bearing allows smooth and stable swinging motion, typically up to 180°–270° for wall-mounted cranes and 360° for floor-mounted or mobile cranes. Bearings are often grease-lubricated and sealed to reduce wear and keep out dust and moisture.
• Articulating Models: Some cranes feature a two-section articulated boom for greater reach and flexibility. These designs include an elbow joint with a secondary pivot bearing and lubrication points. This allows the operator to maneuver loads around obstacles or into confined spaces with ease.

2. Mast or Wall Bracket

The mast or wall bracket is one of the most important structural components of a jib crane. It supports the boom and transmits loads from the hoisted materials down to the foundation or building structure. The type of support—floor-mounted, wall-mounted, or mobile—depends on where the crane will be used, the available floor space, and how much flexibility is needed. Each design has its own advantages, installation requirements, and ideal applications. Choosing the right configuration ensures safe operation, long service life, and efficient use of space.

Floor-Mounted (Pillar-Mounted)

A floor-mounted jib crane uses a vertical steel mast that is welded to a thick base plate and firmly anchored to a reinforced concrete foundation. The base plate is usually secured with heavy-duty anchor bolts, allowing the structure to resist bending moments and shear forces during lifting. Leveling shims are placed beneath the plate to ensure perfect vertical alignment before final tightening. The mast itself is made from high-strength steel tubing or rolled sections designed to carry both the vertical and horizontal loads generated during crane operation. Once installed, the entire structure is often grouted around the base to enhance rigidity and prevent movement. This type of mounting provides excellent stability and is ideal for permanent workstations or areas with high lifting frequency, such as manufacturing plants and maintenance bays.

Wall-Mounted

A wall-mounted jib crane is supported by a gusseted bracket system made of thick, high-grade steel plates. The bracket assembly is bolted or welded directly to the building's structural columns or load-bearing beams. Each bracket is designed with reinforced gussets that distribute stress evenly and minimize deflection when the crane is loaded. To ensure long-term accuracy and performance, all welds are typically stress-relieved to eliminate residual stresses that could lead to distortion or fatigue cracks. Wall-mounted systems are space-efficient since they require no floor support, making them ideal for facilities with limited floor area or where machines and walkways must remain unobstructed. However, installation must be verified by a structural engineer to confirm that the wall or column can safely handle the applied loads.

Mobile

A mobile jib crane combines versatility with convenience. It features a steel mast attached to a reinforced base frame equipped with heavy-duty wheels or casters. The base is designed to maintain stability during lifting while allowing the crane to be moved easily between workstations. For electric models, the mast often includes a built-in battery compartment or power pack to drive the hoist and rotation system. Manual versions come with locking casters or floor brakes to secure the unit during operation and prevent unwanted movement. The base structure is engineered to keep the center of gravity low, ensuring safety when lifting loads. Mobile jib cranes are best suited for workshops, maintenance areas, or warehouses where flexibility and quick repositioning are required without the need for permanent installation.

3. Hoist and Trolley

The hoist and trolley are the heart of the jib crane's lifting system. Together, they perform two key movements—lifting and horizontal travel. The hoist raises and lowers the load vertically, while the trolley allows smooth movement along the crane's boom. This combination gives operators precise control and flexibility when positioning materials. A well-matched hoist and trolley system improves productivity, ensures safe handling, and extends the crane's service life. Choosing the right combination depends on the working environment, load weight, lifting height, and frequency of use.

Electric Chain Hoist

An electric chain hoist is compact, efficient, and easy to maintain. It is ideal for medium-duty applications where space is limited or low headroom is a concern. The lifting mechanism uses a high-strength alloy chain powered by an electric motor, ensuring consistent performance and minimal downtime. Most electric chain hoists feature two-speed motors—a fast speed for general lifting and a slow speed for precise positioning. This dual-speed control helps operators place loads accurately without sudden jerks. Typical lifting heights range from 6 to 9 meters, making them suitable for small workshops, assembly lines, and maintenance areas. These hoists are also known for their low noise, smooth operation, and compact body, allowing easy installation on wall-mounted or pillar-mounted jib cranes. Advanced models may include electronic overload protection, limit switches, and thermal protection to enhance operational safety and prolong motor life.

Wire Rope Hoist

A wire rope hoist is designed for heavier loads and higher lifting heights, often reaching 12 meters or more. Instead of a chain, it uses multiple wire rope falls wound around a grooved drum to evenly distribute the load. This design provides greater lifting power and smoother motion, making it ideal for continuous, high-capacity operations. Wire rope hoists are equipped with multi-speed or variable-frequency drive (VFD) motors, giving operators fine control over lifting and lowering speeds. This precision is essential when handling fragile, valuable, or bulky materials. They also come with robust limit switches, overload protection systems, and electromagnetic brakes to ensure maximum safety. Due to their strength and durability, wire rope hoists are commonly used in heavy-duty industries such as factories, warehouses, steel plants, and shipyards. They require regular maintenance and proper lubrication but deliver exceptional performance and reliability under demanding conditions.

Trolley System

The trolley system supports the hoist and allows it to move horizontally along the jib arm. It ensures that loads can be positioned accurately anywhere within the crane's working radius. The trolley runs on the boom's top flange using sealed roller bearings, which minimize friction and enable effortless movement even when carrying heavy loads. These bearings are maintenance-friendly and protected from dust, ensuring long service life and consistent performance. The trolley's design often includes adjustable side plates, spacers, and end stops to match different beam sizes and prevent derailment during operation.

Drive Options

• Manual Push Trolley: This is the simplest and most economical type. The operator pushes or pulls the load by hand to move it along the beam. It's ideal for light loads and infrequent use, such as in small maintenance or repair workshops.
• Geared Trolley: This system adds a hand-operated gear and chain drive, giving the operator more control when positioning loads. The geared trolley reduces the effort needed to move the hoist and is suitable for moderate loads or where precise movement is important but power is not available.
• Motorized Trolley: A motorized trolley uses an electric motor and gearbox for powered travel along the beam. It delivers consistent and controlled movement with minimal operator effort. Speed can be adjusted using VFD control for smooth acceleration and deceleration. Motorized trolleys are ideal for frequent operations, longer booms, or heavier loads that require precise positioning and repetitive movement.

Safety Features

Trolley systems are equipped with several safety features to ensure reliable operation. Adjustable side plates help maintain alignment with the beam, preventing derailment. End bumpers or stoppers are installed at both ends of the boom to avoid collisions. For motorized types, limit switches and overload protection systems automatically stop motion if the load exceeds the rated capacity or reaches the beam's end. Regular inspections, proper lubrication, and checking of fasteners and bearings are essential to keep the trolley in good condition and to guarantee safe lifting operations.

In summary, the hoist and trolley combination determines how smoothly and safely a jib crane handles loads. Electric chain hoists are compact and efficient for light to medium work, while wire rope hoists handle heavy-duty lifting with precision. The trolley system, whether manual or motorized, ensures smooth travel and accurate positioning along the boom. Together, they form a reliable and flexible lifting mechanism suited for various industrial and maintenance applications.

4. Controls and Power Supply

A solid power source and a dependable control system are essential for safe and effective crane operation. How easily the jib crane operates, how safely it reacts to operator input, and how successfully it guards against electrical problems are all determined by the control and power configuration. A well-designed system lowers the chance of accidents and maintenance downtime in addition to increasing production. In order to make handling easier and more effective, modern cranes frequently incorporate intelligent features like frequency drives, overload protection, and wireless control.

Power Source

Most fixed jib cranes are powered by 380–400 V, 3-phase AC electrical systems, which provide the stability and torque needed for industrial lifting tasks. This voltage range is standard in factories, workshops, and heavy-duty facilities worldwide. Power is usually supplied through a main isolator switch or distribution panel, ensuring the crane can be safely disconnected for maintenance. For mobile or portable jib cranes, lower voltage systems such as 48 V DC battery packs or temporary plug-in AC connections are used to support flexible operation in outdoor or remote sites. The choice of power supply depends on crane capacity, duty cycle, and work environment. Proper grounding and correct cable sizing are essential to avoid voltage drops, overheating, or equipment damage.

Protection Systems

Electrical protection is a vital part of any crane system. Common protective components include fuses, circuit breakers, thermal overload relays, and ground-fault protection. These devices prevent issues like short circuits, current surges, and overheating from damaging the electrical components or posing risks to operators. Overload relays automatically disconnect the motor when it exceeds its rated current, while ground-fault protection detects any unintentional current flow to earth, preventing shocks and fire hazards. Many modern cranes also feature emergency disconnect switches, allowing operators to cut power instantly in unsafe conditions. Routine inspection of electrical enclosures and connections ensures long-term reliability and compliance with safety standards such as IEC and ISO.

Control Methods

• Pendant Station: A pendant station is a wired push-button controller that hangs from the hoist or boom, allowing direct and simple operation. It typically includes directional controls for lifting, lowering, and swinging, along with a start/stop switch and an emergency stop button. The cable runs along the boom using a festoon system or spring-loaded cable reel to prevent tangling and ensure smooth movement. Pendant controls are durable, easy to maintain, and ideal for precise, close-range operation. They are commonly used in workshops and manufacturing plants where the operator needs to stay near the load for accurate positioning.
• Wireless Remote Control: Wireless remote control systems offer greater freedom and safety. They use a radio transmitter operated by hand and a receiver mounted on the crane's mast, boom, or trolley. The remote typically includes dead-man buttons, meaning the crane stops immediately if the operator releases the control—an important safety feature. This setup allows operators to control the crane from a safe distance, improving visibility and reducing exposure to hazards such as suspended loads or hot zones. Wireless remotes often have programmable buttons for multiple motions, speed control, and safety interlocks. They are widely used in modern factories, outdoor yards, and environments requiring flexible or long-range operation.

5. Durable Construction

All steel frames are welded and stress-relieved to avoid distortion. Bearings and rollers use C3 or C4 grade sealed bearings for long life. The chain or wire rope is galvanized or lubricated for corrosion protection and reduced wear.

Precautions for Use

1. Proper Training

Only trained and authorized personnel should operate a 3 ton jib crane. Operators must understand load charts, swing paths, and emergency procedures.

2. Daily Pre-Operation Inspection

Walk around the crane before each shift. Check for loose bolts, chain or rope wear, hook deformation, and unusual noises during a test lift.

3. Verify Load Capacity

Never exceed the 3 t rated capacity. Ensure rigging hardware (slings, shackles) is sized for at least 5 t for safety. Always center the load under the hook.

4. Clear Working Area

Keep personnel and equipment out of the swing radius. Mark the floor with safety lines, especially in high-traffic zones.

5. Controlled Motion

Lift straight up, move at a steady speed, and lower smoothly. Avoid sudden starts or stops to reduce load sway.

6. Avoid Side Pulling

Never lift with the load off-center on the boom. Side pulling creates moments that can warp the mast or damage bearings.

7. Lockout/Tagout for Service

Before any maintenance, cut power at the main switch and lock it out. Tag the crane to prevent accidental reactivation.

8. Environmental Awareness

Do not operate in high winds (for wall-mounted units). Keep cranes clean in dusty or corrosive atmospheres. If exposed to moisture, ensure electrical enclosures remain sealed.

Selection Guidelines

1. Identify Lift Requirements

Determine the maximum load weight, lift height, and pickup/drop-off locations. A 3 t jib crane for sale typically handles pallet racks, engine components, or small assemblies. Define whether you need moderate lift height (up to 6 m) or extended heights (up to 12 m).

2. Choose the Right Mounting Style

• Wall-Mounted: Ideal when floor space is scarce and there is a strong structural wall.
• Floor-Mounted: Best for central lift points where wall support is not available. Requires a concrete foundation.
• Mobile: Offers temporary lift points. Choose when lifting needs change frequently.
• Wall-Travelling: Covers a long, linear area. Suitable for machine tool lines or paint booths.
• Articulating: Provides flexibility to reach around obstacles.

Select Boom Length and Swing Arc

Based on your workspace, pick a boom length that covers the lift zone without interfering with other equipment. Choose a swing arc (180°, 270°, 360°) to balance coverage and crane placement. For maximum coverage, a 360° rotation on a floor-mounted crane is preferred. For wall-mounted units, 180°–270° is typical.

Pick a Hoist Type

You can choose the right type of hoist for your needs:

• Chain Block:
• Electric Chain Hoist: Lower initial cost, compact design, low headroom. Suitable for lift heights ≤ 6 m.
• Wire Rope Hoist: Smooth lifting, handles higher lifts (up to 12 m). More expensive but better for frequent use.

Assess Duty Cycle

Consider how often you will run the crane. For heavy-duty or continuous service, choose components rated for higher duty class (ISO M5–M7). Less frequent lifts may use standard-duty chain hoists.

Confirm Power and Controls

Verify your facility's power supply (380 V/400 V, 3-phase) and ensure crane control options (pendant, wireless remote, cabin) match your workflow. Mobile cranes need battery chargers or a generator.
