3 Sets of 10 ton Single Girder Bridge Crane for Philippines

Recently, Yuantai Crane supplied 2 sets of 10 ton single girder overhead crane and 1 set single girder overhead crane with 2 nos. 5 ton electric hoist to Philippines. Let's check the details.

On April 4, 2024, Leandro from the Philippines contacted Yuantai Crane, asking three sets of single girder overhead cranes. The customer works in a general industrial facility where lifting heavy machines and transferring large products are common occurrences. In such settings, dependable overhead cranes are critical for safe and efficient material handling. Aging cranes and insufficient lifting capacity were impeding operations, necessitating the need for improved systems that could carry 10-ton loads while smoothly integrating into current workplace layouts.

Customer Needs and Specific Requirements

Leandro gave detailed drawings and a full crane configuration list. He wants reliable cranes that fit his existing workshop exactly. He needs gear that handles both single and tandem lifts. He also needs minimal downtime. Delivery must match his construction schedule. Safety, stiffness, and precise control rank high. We used those priorities to shape the technical choices below.

1. Project Requirements

Leandro requires three single-girder overhead cranes. One crane will carry two 5-ton electric hoists for dual or tandem lifts on the same runway span. Two other cranes will each have a single 10-ton electric hoist for heavy components like machine bases, die sets, and assembly parts. All main beams must be box girder construction with thicker steel plates for extra stiffness. The hoists should be European-style electric units for precise speed and reliable performance. Span and headroom must match his workshop drawings so the cranes fit the runway and tooling. He also asked for a short lead time to reduce project delays and downtime.

2. Rated Capacity and Load Handling

Specify the safe working load (SWL) clearly for each crane: 10 tons for the two larger cranes and 5 tons per hoist for the dual-hoist crane. Design the hoists, trolleys, and end carriages to handle dynamic forces and load offsets seen in real lifting. Include margin for shock and side-pull conditions. Require proof testing and load certificate at handover. Fit visible load indicators and limiters to prevent overload. Also plan for tandem-lift controls or synchronous drives when two hoists share a single load.

3. Main Beam Type — Box Girder Design

Use box girder main beams built from thicker steel plates. This form gives high rigidity and low deflection under uneven loads. Specify internal stiffeners and full-penetration welds at high-stress zones. Protect the beam with corrosion-resistant coating, and include access points for inspection.

4. Hoist Type — European-Style Electric Hoists

Choose European-style electric hoists for their precise control and proven reliability. These hoists typically offer variable speed control, accurate positioning, and high duty cycles. Make sure they include overload protection, emergency braking, and thermal monitoring. Specify gearboxes and motors that allow smooth starting and stopping. Ensure spare parts are available locally.

5. Span, Headroom, and Dimensional Fit

Match the crane span, hook approach, and headroom to the workshop drawings exactly. Check runway beam spacing, runway camber, and crane runway loadings. Decide whether a low-headroom trolley or compact hoist is needed to maximize hook lift. Account for overhead obstructions, lighting, and ductwork. Provide clearances for maintenance access and for the crane to pass under service structures.

6. Timely Delivery and Project Coordination

Plan production with short lead time in mind. Identify long-lead items early, such as hoists, drives, and electrical panels. Schedule factory acceptance tests (FAT) before shipment. Coordinate shipping, site erection, and commissioning with the client’s construction milestones. Provide a clear delivery schedule and contingency plans for delays. Deliver full documentation with the cranes: test certificates, wiring diagrams, operation manuals, and spare-parts lists.

7. Additional Technical and Safety Notes

Include tandem-lift controls if the two 5-ton hoists will lift a single heavy load. Provide synchronized drive or load-sharing systems and independent overload detection on each hoist. Fit limit switches, emergency stops, and anti-collision or zone-limiting features as needed. Prepare a maintenance plan and a spare-parts kit for common wearing parts. Offer operator training and a commissioning checklist to ensure safe, reliable service from day one.

Challenges Faced Before Adopting Yuantai's Solution

1. Inadequate Beam Strength and Deflection Issues

Previous cranes utilized I-beam girders. Under large loads, these beams showed substantial deflection. When lifting 8-10 ton components, operators reported up to 20 mm of sag in the middle of the span. This deflection resulted in mismatched loads and increased wear on the hoist trolley wheels. Frequent repair and replacement of worn wheels became normal, lowering total equipment availability.

2. Limited Lifting Precision and Reliability

Older wire rope hoists at the plant lacked precise speed control. Operators struggled to switch between quick lifts and slow placement. As a result, large components occasionally crashed with neighboring objects or swung dangerously before landing. This jeopardized workplace safety and raised the likelihood of damage to expensive tooling and machinery.

3. High Cost from Competing Suppliers

Leandro requested bids from many local and international crane vendors. Many offered custom solutions with long delivery dates and hefty prices. Some quoted double girder cranes that cost more than the client could afford for minor lifting requirements. The customer required a cost-effective solution that did not sacrifice quality or safety.

4. Uncertain Installation and Commissioning Support

The client's maintenance team lacked experience installing box girder cranes. They were concerned about matching new girders with existing runway beams and calibrating the hoist controls. Without solid technical support, there was a substantial danger of erroneous installation. This could cause operational delays and safety issues.

Project Implementation and Delivery Process

In order to ensure that the final delivery fully meets the customer's usage requirements, we maintain communication throughout the transaction, agreeing on technical specifications, quality checks and logistics in the pre-transaction phase.

1. Quotation and Technical Discussions

Leandro reviewed Yuantai’s proposal quickly and compared it with rivals. He said that our price is very advantageous, and they are more concerned about the delivery time, if we can provide faster delivery cycle, they will prioritize to work with us. Our team answered their technical questions via videoconference and presented relevant drawings, material certificates and examples of previous deliveries. We also provide on-site commissioning and installation to ensure that the final delivery goes smoothly.

2. Production and Quality Control

Yuantai has established a comprehensive quality monitoring system, so all parts in the workshop need to be tested and qualified before they can be used. Our factory has a professional metal fabrication shop with several machining centers and metal cutting machines to provide steel plates for the workshop. The steel plate after welding also needs to be sprayed with top coat to achieve durable effect, we will spray different kinds of paint and surface treatment according to your usage environment. When the final product is completed, it is subjected to no-load testing, 125% full-load lift testing, and safety inspections. All tests are completed before the device is allowed to leave the factory.

3. Packing and Shipping

In packaging, in order to minimize the damage caused by bumps on the goods during transportation, our crane girder boxes are packed in plastic and fixed pads underneath the girder. The individual parts of the crane are secured in wooden crates with foam and shock-absorbing plastic. Desiccant was placed in the wooden box.

4. On-Site Installation and Commissioning

Yuantai sent three field engineers for installation support and safety oversight. They verified runway rails and adjusted supports to keep alignment within ±5 mm over the 10 m span. They welded anchor plates, mounted end carriages, and assembled trolleys and hoists. The engineers performed incremental load testing and checked brakes, limit switches, and sway control. We also end up training local technicians in operation, emergency stops and routine maintenance.

Advantages of Yuantai's Overhead Crane Solutions

Yuantai's overhead cranes strike a balance between strength, precision, safety, and affordability. Each feature is intended to enhance your lifting operations, minimize cycle times, and lower total cost of ownership.

1. High Structural Integrity and Minimal Deflection

The box-girder main beams have 25 mm flange plates and 12 mm webs. Under a full 10 ton load, beam deflection remains below 6 mm. This stiffness keeps the hoist and load steady, minimizing swing. Stability is essential when positioning heavy or sensitive equipment. Less sway means more time spent on productive work rather than re-aligning loads.

2. Precision Lifting and Speed Control

Dual-speed European hoists allow rapid material movement and gentle load placement. The slow speed of 2.5 m/min offers fine adjustment when aligning delicate machinery. Fast speed of 8 m/min reduces idle time when moving empty hooks or light loads. The CT speed of 12 m/min in trolley travel cuts cycle times across the 10 m span.

3. Enhanced Safety Features

Each hoist has an overload limiter that disables power when loads surpass 110% of the rated capacity. Upper and lower limit switches prevent excessive travel, which could harm the trolley or hook. During a power outage or an emergency stop, an electromagnetic disc brake in conjunction with a spring-loaded mechanical brake keeps the load secure.

4. Cost-Effective and Competitive Pricing

Compared to other suppliers, Yuantai's offer combined high-quality European hoists with robust box girders at a lower price point. Modular design minimized shipping volume and reduced freight costs. The client praised the high quality and low price in post-order feedback.

5. Flexible Installation Support

Every purchase includes 10 days of on-site commissioning by Yuantai experts at no additional cost. If your team chooses to install in-house, we provide full installation manuals, 3D CAD blueprints, and remote video support.

Broader Applications for 10 Ton Single Girder Overhead Cranes

The 10-ton single-girder crane delivers reliable lifting in diverse settings. Its dual-speed hoist and low-headroom design adapt to tight spaces and heavy loads.

1. Manufacturing Workshops

These cranes streamline part handling in machine shops and tool rooms. They lift heavy spindle housings, gearboxes, and large assembly fixtures onto CNC mills and presses. The 10-ton capacity handles raw castings or forgings, while the low-speed mode lets operators position workpieces within millimeter accuracy. Quick repositioning at high speed minimizes idle time between load picks.

2. Automotive Parts Production

In engine and transmission lines, the crane moves blocks, cylinder heads, and gearbox assemblies. Its box-girder beam supports heavy die sets and mold bases. With only 600 mm of hook-to-rail clearance in low-headroom models, it fits under mezzanine platforms and service galleries. Pendant and remote controls let technicians switch between floor and catwalk operation for efficient parts flow.

3. Warehousing and Distribution Centers

The crane speeds up pallet transfers between staging zones and loading ports. A CT travel velocity of 12 m/min may cover bays as broad as 20 m without slowing down. Operators can use a pendant control for spot lifts or a wireless remote for ground-level handling. The single-girder design frees up above space for lighting and sprinkler systems.

4. Construction Material Handling

The crane raises girders, formwork, and pre-cast panels using temporary steel runway beams. It can handle 10 t bundles of rebar or plywood sheeting in one lift. Two 5 t hoists work in tandem to carry big modules. The modular runway and bolt-together columns allow you to install or reposition the system week by week as the project progresses.

5. Energy and Power Plants

During turbine overhauls and generator installations, the crane manages rotors, stators, and heat-exchanger bundles. Fine-tune the load position with the crane's low-speed hoist mode to align shaft journals or bolt holes. The steel box girder resists thermal expansion and vibration common in power-generation buildings. Its simple single-girder frame fits inside tight turbine hall headrooms without requiring crane rails at multiple elevations.

Customer Feedback and Outcomes

We compared several suppliers, but Yuantai offered the best combination of quality and price. The 10 m spans and low headroom design fit our workshop perfectly, without altering our roof structure.
