A customer from India contacted us looking for a bridge crane solution. They contacted us through our website and after browsing our HD single girder overhead cranes page, they wanted us to provide them with a suitable lifting solution. According to customers, they usually cut, weld, and assemble structural steel beams, trusses, and frames mainly for the construction and engineering industries. They wanted to buy cranes for a new factory building. The customer attached very detailed information in the e-mail, not only provided the parameter drawings of their factory, but also provided the detailed parameters of the required crane. So our experienced sales team quickly gave an initial proposal.
Customer Needs And Pre-Implementation Challenges
Before selecting the new crane, the steel fabrication plant in India faced clear lifting and efficiency limits that affected daily production and safety. You needed a crane that could handle heavy I-beams weighing up to 4.5 tons with confidence, so a 5 ton safe working load was essential to give you a safety margin and allow bundled lifting without stress on the system. At the same time, a 12 m bridge span was required to serve three assembly bays in one run, helping you avoid extra runway columns that would reduce floor space and disrupt workflows. Lifting height was another key concern, as steel sections had to clear jigs and welding stations at heights of up to 4.5 m, while dual hoisting speeds were necessary to balance speed and precision, with fast lifting for approach and slow lifting for accurate positioning. To keep material moving efficiently between workstations, trolley travel speeds of up to 20 m/min were needed to cut idle time. Because your plant operates two long shifts each day, the crane also had to meet an A5 duty classification under ISO 4301-1, ensuring it could handle frequent cycles without premature wear, while built-in safety features such as overload protection and anti-sway control were critical to meet Indian safety regulations and protect operators. Previous 3 ton cranes could not lift combined loads, and forklifts created safety risks in tight aisles, leading to slow positioning, frequent re-rigging, and high annual downtime from maintenance failures.
Lifting Requirements
During the communication, the customer listed the following technical specifications that must be met:
| Demand | Specific parameters | Reasons |
|---|---|---|
| Rated lifting capacity | 5 tons | The heaviest workpiece is about 4.5 tons, and 5 tons ensures a safe margin. |
| Span | 12 meters | The new plant has three side-by-side assembly stations with 12-meter spans that can be covered at once. |
| Lifting height | 6 meters | The need to get the steel beam over the jig and welding platform while matching the worker's standing operating height. |
| Lifting speed | Dual speed (fast + slow) | Fast (approx. 5m/min) for empty hooks or fast lifting and lowering, and slow (approx. 0.8m/min) for placing the steel beams accurately into the welding station. |
| Job level | A5 (ISO 4301-1) | Cranes are used frequently and need to be able to withstand a high number of cycles. |
| Security Configuration | Overload protection, anti-sway | Meets local Indian safety regulations while protecting operator safety. |
Product Design And Technical Specifications
The specifications of the cranes we offer to our clients are listed below:
1. HD Series Single Girder Bridge Crane Structure
We supplied an single girder bridge crane rated 5 t with a 12 m span and 6m lifting height. The main beam is a welded box section fabricated from Q235B structural steel. Under full load the deflection stays below L/750, which meets common industry stiffness targets and helps keep trolley tracking and hook positioning accurate. The entire crane structure is carefully designed. After manufacturing, our quality inspectors carefully inspect the crane structure and apply highly durable primer and topcoat.
2. End Carriages And Runway Rails
The forged steel wheels on the end carriages are powered by 43 kg/m crane rails, which are industry standard. In order to minimize maintenance intervals and keep out dust and welding spatter, wheels are powered by sealed roller bearings with an IP65 rating. In order to install the rails without the need for additional heavy civil work, wheelsets and bearings were statically positioned on prefabricated steel brackets; this improved alignment precision and shortened installation time. Wheel tread hardness and profiles were specified to limit wear and extend service life under the anticipated operating cycles, and wheel and rail contact geometry was examined for appropriate load distribution.
3. Electric Wire Rope Hoist
For accuracy and speed, the crane uses an electric wire rope hoist with a dual-speed transmission. It can lift objects at a slow speed of 0.8 m/min for precise positioning and quickly at 5 m/min for efficient travel. For fatigue and abrasion resistance, the hoist uses steel wire rope that is scaled and defined with a 6:1 safety factor in relation to SWL. When power is gone, the braking system's spring-applied, magnetically released architecture offers positive holding. The hoist assembly has a sealed gearcase, replaceable wear parts for the sheave and drum, thermal protection for the motor, and provisions for regular rope replacement and inspection.
4. Trolley And Bridge Travel Drives
Both trolley and bridge motions use VFD-driven electrical motors for smooth, controllable travel. The trolley speed range is 2–20 m/min and the bridge travel range is 3–30 m/min. Each drive has soft-start and soft-stop capability to limit acceleration and deceleration, which reduces jerk and minimizes load swing. Drives include motor overload and thermal protection, regenerative braking as required by site conditions, and adjustable ramp profiles to tune anti-sway performance. Cabling is routed in festoon or cable-trough systems and drive panels are mounted in IP54 enclosures for dust and splash protection.
5. Control And Safety Devices
A pendant station with an emergency stop and a dead-man switch is part of the control suite. Based on a strain-gauge load cell, we installed an overload limiter that records trips for maintenance review and sounds an alarm and shuts power when the predetermined threshold gets close to 100% SWL. Over-travel is prevented by end-travel switches and upper and lower hoist restrictions. VFD acceleration ramps regulate anti-sway, and if tighter placement is needed, PLC-based active sway control can be added. Grounding, phase-loss protection, and fault indicators are included, and all electrical cabinets and motors have an IP54 rating. Functional safety checks and a proof load test are part of final commissioning, which confirms performance prior to handover.
