Features of double girder overhead crane with hoist trolley

The crane bridge's double girder structure provides sufficient strength, rigidity, and stability.
The rail-in-middle box girder design satisfies the requirements for strength, rigidity, and stability.
Simple-structured end beams can be easily installed with the main beam of the double girder crane by using high-strength bolts.
As for the lifting mechanism, a high quality CD or MD wire rope electric hoist is used, which also can be designed with your lifting retirements.
Soft starting motors with low current are used in conjunction with ground overhead crane control.
A dual-motor independent drive device is used to reduce rail gnawing wear and the possibility of wheel climb off track faults. etc.
The motor is directly controlled by a contactor, which allows for single and double speed control as well as reversing.
A frequency converter is used to change the frequency and voltage of motor power in order to realize the function of motor speed control.
A multi-level safety protection system is used, which includes short circuit protection, no-voltage protection, emergency power off switch protection, overload limit protection, travel limit protection, zero and chain protection, ground protection, and other features.

Frequently Asked Questions – LH Series Double Girder Overhead Crane

This FAQ addresses common concerns of crane buyers, covering industrial applications, typical loads, workshop conditions, energy efficiency, maintenance, purchasing decisions, and cost considerations for general material handling.

It is designed for general material handling across multiple industries.

Ideal for workshops, warehouses, steel fabrication plants, automotive assembly lines, precast concrete factories, and shipyards.
Works well in both indoor facilities and partially sheltered yards, depending on protective options.

It can lift anything from 5 to 63 tons, depending on the model.

Common loads include steel plates, beams, billets, ingots, pallets, concrete molds, engines, and machinery parts.
Confirm load weights and dimensions to ensure proper hoist selection and duty class.

You need to measure both the building span and headroom for safe operation.

Ensure the crane span fits your workshop width and length, and the lifting height clears overhead obstructions.
Check space for endcarriage travel and load swinging; tight spaces may require low-headroom designs.

Yes, it is rated for ambient temperatures between -20°C and 40°C.

Suitable for dusty or moderately hot indoor workshops, steel mills, or foundries.
For outdoor or corrosive environments, consider weatherproof hoist covers or protective coatings.

It is designed to reduce energy use while maintaining stable performance.

Dual girders improve load stability and reduce vibration, lowering wasted energy.
CD/MD hoists operate smoothly with minimal power consumption, especially under moderate lifting cycles.

Regular inspection and lubrication of hoist trolleys, wheels, bearings, and endcarriages are recommended.

Duty class A3–A5 determines inspection intervals based on lifting frequency.
Proper maintenance prevents downtime and prolongs crane lifespan.

Match capacity, span, and lifting height to your typical loads and workshop layout.

Assess maximum and average load weights, lifting frequency, and dimensions.
Decide on hoist type, control options, and optional automation for precision or remote operation.

Choose a model that fits your lifting needs without over-specifying capacity.

Oversized cranes increase cost unnecessarily, while undersized cranes risk overloading.
Consider energy use, installation costs, and maintenance when comparing options.

Provide detailed specifications and clarify optional features.

Include lifting capacity, span, lifting height, duty class, hoist type, and control method.
Ask about optional accessories like limit switches, weatherproof covers, or remote control systems.
Confirm warranty, delivery, and installation support.

It adapts well to indoor workshops, maintenance bays, and partially covered yards.

Check runway beam strength, floor capacity, and headroom clearance.
Outdoor installations may require anti-corrosion treatment or hoist covers.

CD hoists are suitable for moderate, intermittent lifting; MD hoists are for heavier, more frequent loads.

CD hoists are cost-effective for lighter or occasional lifts.
MD hoists are robust for continuous heavy-duty operations, reducing wear and downtime.

Space, load variations, energy supply, and installation feasibility are common concerns.

Ensure the crane can handle varying load sizes and weights safely.
Verify that the facility layout allows smooth endcarriage travel and sufficient hook clearance.
Check if energy supply meets operational requirements for frequent lifting cycles.

By combining durability, energy efficiency, and low maintenance needs.

Dual-girder construction reduces deflection, extending component life.
Customizable spans and heights avoid oversizing and save on installation and operating costs.
