PRODUCTS & CASES

Double trolley overhead cranes are bridge cranes equipped with two independent complete hoisting trolleys. Distinct from single-trolley dual-hook cranes (one heavy-duty main hook + one light auxiliary hook), the two trolleys on this model generally carry identical rated capacities, and each trolley can further be fitted with its own main and auxiliary hooks as required. The dual independent trolley layout is developed to satisfy complex synchronous hoisting and special process working conditions.

This crane model is widely applicable to power stations, metallurgical plants, steel mills, general workshops, warehouses, papermaking factories, shipyards and other sectors.

Common matching capacity specifications: 5+5t, 20+20t, 100+100t, 150+150t, 160+160t, 200+200t, 300+300t, etc.

Weihua’s full series overhead lifting equipment is extensively deployed across mechanical manufacturing, metallurgical smelting, power generation, railway logistics, port terminals, petroleum exploitation and chemical processing industries. Our cranes provide reliable heavy-load handling support for numerous national key construction projects and production bases of large industrial conglomerates worldwide.

Weihua Crane supplies fully tailor-made double trolley overhead crane packages dedicated to machinery manufacturing plants, integrated steel mills and large-scale industrial workshops. Featuring matched dual equal heavy-load capacity and synchronous precise manipulation, these custom cranes deliver stable performance for synchronous hoisting, flipping and precision assembly of oversized heavy workpieces.

All core technical indicators including lifting tonnage, working span, vertical lifting height and track width can be flexibly adjusted to fit diverse factory building layouts and strict dual-trolley coordinated heavy lifting standards, supporting consistent efficient and secure round-the-clock heavy-duty production.

Optional Configurations

• Full-electric and hybrid trolley driving assemblies

• Unmanned automatic operation system supporting wireless remote control

• Dedicated intelligent anti-sway and high-precision positioning unit for synchronized heavy workpiece handling

• Energy-saving drive units with regenerative braking function

• Custom structural optimization to match unique runway layouts inside large industrial workshops

Our professional R&D engineering team prioritizes high synchronous hoisting efficiency, comprehensive redundant safety monitoring protection and extended equipment service lifespan, supplying state-of-the-art dual-trolley coordinated lifting solutions for modern machinery factories, steel structure fabrication plants and all large heavy industrial production workshops.
