QBE Explosion-Proof Double Trolley Double Girder Overhead Cranes: Precision Lifting for Heavy-Duty Applications

Explosion-proof double trolley double girder overhead crane in the picture is a larger explosion-proof crane equipment in China, used in the aerospace industry. It consists of two 160t lifting explosion-proof trolleys, heavy-duty bridge and three-in-one transportation drive.

Double trolley can be synchronized lifting and lowering, synchronous lifting and workpiece turning operations, precise lifting of goods, explosion-proof class DIICT4, combined with the new crane design concept, design and manufacturing to meet the GB national standards and FEM European standards.

The whole vehicle hardened gear reducer, frequency drive, multiple safety protection, streamlined structure, environmental protection and low energy consumption. It can be used in various explosion-proof or other environments with high safety requirements.
