A Hong Kong terminal needed reliable, space-efficient bridge cranes to move and temporarily store mer·chan·dise across multiple shuttle racks. We delivered 5-ton LD model single-girder bridge cranes equipped with two electric wire-rope hoists per crane.

What the Customer Needed at the Terminal

5-ton-ld-bridge-cranes7

In order to reduce the time that ships spend in port, the customer built a temporary storage site consisting of a steel structure filled with shelves near the pier. Customers say that usually, once the ship arrives, they need to move the cargo to the storage site as soon as possible. However, due to the distance from the warehouse, it takes a lot of time to move the cargo, resulting in higher costs due to longer ship docking times. That's why they recently built this temporary storage site at the marina. The client wanted us to provide a cost-effective and durable solution as they had a limited budget.

5-ton LD Bridge Crane — The crane design we provided

Product overview — LD model single-girder bridge crane with dual wire-rope hoists

We supplied 5-ton LD bridge cranes configured with two independently controlled electric wire-rope hoists mounted on a single bridge. Key delivered components and design choices:

  • Two electric wire-rope hoists (Yuantai CD style), each rated for up to 5 tons working load. Hoists are installed on a common trolley or on two trolleys depending on aisle width and load handling patterns, giving the operator the choice of using hoists individually or in coordinated mode for special lifts.
  • Variable frequency drive (VFD) controls for smooth acceleration/deceleration and energy-efficient travel and hoist speed control (improves precise placement in shuttle racks).
  • Safety devices and instrumentation including overload protection, anti-two-block, limit switches, rope condition access points, audible/visual alarms, and operator cabin or pendant ergonomics per ASME B30.2 and local regulatory best practice.
  • Duty class and materials sized to match the customer's cycle counts and load spectrum (ISO/Cranes duty classification applied during design; single-girder cranes are typically economical for light-to-medium duty profiles).
  • Why Offer a Double Hoist Design?

    The double hoist design allows customers to use the crane with greater control, higher safety and more flexible maneuverability. It centralizes two lifting points on the same bridge, allowing customers to easily move long, heavy or irregular items.

    1. Handling Long or Large Loads

    Long or bulky items — think steel beams, pipe bundles, or turbine blades — will tilt or swing if lifted from a single point. Using two hoists lets you lift from two locations on the same load so it stays level and stable. That cuts the risk of damage and makes travel through tight spaces much safer for both your staff and the load.

    2. Main and Auxiliary Hoist Combination

    In many projects, cranes are fitted with a main hoist and an auxiliary hoist on the same bridge. The main hoist is used for heavy lifting, while the auxiliary hoist assists with lighter tasks such as load stabilization, turning, or precise positioning. This arrangement improves accuracy and efficiency, especially during assembly or installation work.

    3. Load Distribution and Safety

    Two hoists spread the forces across the bridge and runway instead of concentrating them on one point. That lowers stress on the crane structure and runway beams and reduces wear on components. The result is fewer repairs, a longer service life, and a smaller chance of accidentally overloading any single hoist.

    4. Synchronized Lifting for Precision

    When a lift needs to be perfectly level or moved in millimeter increments, synchronized hoists are essential. Modern control systems let you move both hoists exactly the same amount at the same time, so the load stays flat and predictable. This precision is crucial when fitting large equipment or molds where even small misalignment can cause costly delays.

    5. Flexibility in Operations

    Two hoists give you operational choices: run them together for dual-point lifts or operate them separately for different tasks on the same shift. That flexibility reduces crane idle time and lets you handle a wider variety of jobs without swapping equipment.

    6. Rotation and Load Turning

    When loads need to be rotated or flipped, two hoists make the task much safer. Operators can attach the hooks at different points on the load, then carefully lift and turn it without risking sudden swings or dropping.

    5-ton LD Bridge Crane — Advantages of the product we provided

    The 5-ton LD Bridge Crane we supplied is built for real terminal work. It gives more usable lifting height, keeps project costs down, and speeds up repetitive moves inside tight spaces.

    1. Wire-Rope Hoist Benefit

    Using a wire-rope hoist gives you extra headroom because the rope winds neatly on a drum, which reduces the hoist package height. Wire rope also handles continuous, repetitive lifts well and runs smoother at higher travel speeds, so cycle times stay short and loads are steadier during transfers. Maintenance is straightforward: routine rope inspection and drum checks keep the hoist reliable.

    2. Single-Girder Bridge

    A single-girder bridge uses less steel and a smaller trolley, which lowers your manufacturing and shipping costs right away. Because it produces smaller runway loads, you save on installation and on any structural reinforcement the building might need. The simpler trolley and travel gear reduce maintenance work and parts costs over time, too. Following CMAA single-girder specifications gives you a clear quality standard, so you get a crane that is both economical and fit for light-to-medium duty tasks like staging and frequent short moves.

    3. Flexibility with Two Hoists

    Two independently controlled hoists on one bridge allow operators to load and unload nearby shuttle racks without moving the bridge as frequently. This shortens cycle time and idle. The second hoist serves as operational redundancy, reducing production impact from hoist maintenance or failure. Operationally, this corresponds to measurable throughput gains in high-frequency short-move scenarios common in terminals.

    Yuantai Girder Overhead Cranes for Light and Medium Lifting Duties

    Comparison of Different Designs of 5-ton LD Single Girder Overhead Cranes

    In comparison to alternative possibilities, the LD single-girder bridge crane is a practical and efficient choice when evaluating lifting solutions in the 5-ton capacity range. It lowers the dangers associated with manual handling, offers dependable coverage over a whole bay, and boosts productivity for light-to-medium production lines, warehouses, and workshops. Beyond lifting capacity, its real advantages include increasing headroom, reducing the need for structural alterations, and providing a longer service life at a lower total cost of ownership.

    1. 5 Ton Wire-rope Hoist vs 5 Ton Chain Hoist

    For the 5-ton range, a wire rope hoist often gives you the best blend of performance and durability. Wire rope saves headroom, lifts faster, and runs smoother, so it shines in repetitive or higher-lift work. Chain hoists stay attractive where space is tight and capacity is small, but at 3–5 tons they get heavier, slower, and harder to service. When you choose, think about duty cycle, lift height, and how often you'll run lifts each day. Also weigh initial cost against lifetime costs: wire-rope hoists usually cost more up front but last longer in medium-to-heavy use if you inspect and replace rope on schedule. If your environment has dust, heat, or corrosion, factor that into the hoist choice and your maintenance plan.

    2. Single Girder vs Double Girder Decision

    Decide between single and double girder by matching the crane to your loads, span, and required hook height. Single girder cranes suit most 5-ton jobs because they save weight, lower cost, and simplify maintenance. Double girder cranes add stiffness, higher hook travel, and are better for very wide spans or heavier, frequent lifting — which is why they're common above roughly 10–16 tons or for special applications. If you expect to scale up or need very precise handling, plan for a solution that gives the flexibility you need and check with a structural or lifting engineer before you buy.

    Other applications for the product beyond this customer

    The crane was designed for the customer's application in this case, but this crane is suitable for a variety of other applications. Whether it's a fabrication shop, maintenance or repair shop, this crane is easily adaptable to a variety of applications.

    1. Steel Fabrication and Plate Handling

    Perfect for transferring assemblies, plates, and frames into storage racks or between welding and fabrication stations. In busy shop layouts, the low headroom profile and accurate hoist control increase placement accuracy and lower the chance of damaging fragile or partially finished assemblies.

    2. Manufacturing Assembly Lines

    In assembly factories, short, repetitive lifts and high cycle counts (M3/M4 duty) are typical. When performing hoist maintenance, the twin-hoist configuration enables balanced lifting of longer workpieces, simultaneous handling of subassemblies. This makes it very helpful in production lines for heavy machinery, appliances, and cars.

    3. Rail/vehicle Maintenance Workshops

    supports the lifting of structural elements, bogies, engines, and wheelsets when controlled tandem lifts and exact positioning are crucial. By ensuring balanced handling of asymmetrical loads, the dual-hoist function enhances workflow and safety in the workshop.
