Overhead crane with double trolley is an overhead bridge crane with 2 separated lifting mechanism. Different from the 1 trolley with 2 hooks (main hook for large capacity and deputy hook for small capacity), commonly the 2-trolley (each trolley can be also with main and deputy hooks) have the same capacity. People use 2-trolley mechanism for special working conditions.

The double trolley overhead crane can be used at power plant, metallurgy plant, steel plant, workshop, warehouse, papermaking, shipbuilding, etc. Capacity: 5+5t; 20+20t; 100+100t; 150+150t; 160+160t; 200+200t; 300+300t, etc.

Key Features of Double Trolley Overhead Crane

• The whole crane adopts frequency conversion and PLC control, which has stable lifting, small impact and less noise;

• The trolley adopts European-standard design with compact structure, overall processing of trolley frame with high assembly precision;

• The bridge structure finite element analysis makes the structure more optimized and more reasonable;

• The components are durable and maintenance-free, equipped with hardened surface reducer, welding reel, rolling pulley and forged wheel;

• Fast on-site installation without welding works;

• CTS electrical modular system, convenient maintenance;

• The whole crane is equipped with safety monitoring system and crane electric correcting device, and reserves interfaces of electrical intelligent anti-sway, intelligent jog, automatic positioning, remote monitoring and other interfaces.
