QE Type Double Trolley Double Girder Overhead Crane
QE Type Double Trolley Overhead Crane is double girder lifting equipment equipped with two independent trolleys. The trolleys can operate separately or synchronously for coordinated lifting, suitable for long profiles, large components and workpieces requiring two-point hoisting. Mounted on workshop corbel rails, it covers rectangular working area via crane longitudinal travel, trolley cross travel and hook vertical lifting. With stable …
Technical Parameters
Features and benefits
01 Main Girder
The main girder serves as the main load-bearing structure of the double girder overhead crane, adopting a welded box-type solid web structure, including normal rail box type and deviated rail box type. The crane is equipped with two parallel main girders with prefabricated camber, which effectively compensates deflection deformation under heavy load and ensures stable operation. The main girder is fitted with maintenance walkways and safety guardrails to provide safe conditions for daily inspection and maintenance work.
02 End Carriage
End beams are transverse load-bearing components installed at both ends of the crane bridge. They connect the two main girders to keep parallel arrangement and stabilize the overall bridge structure. Wheel sets are mounted at the bottom of the end beams. Driven traveling wheels enable the whole crane to move smoothly along the track. The end beam adopts a split structure, which can be disassembled for transportation and bolt-assembled on site for convenient installation.
03 Hoist Trolley Winding Mechanism
The double trolley mechanism is the core winch unit of QE type overhead crane, consisting of two independent winch trolleys. Each trolley is normally equipped with a main hook. The two lifting trolleys can operate separately, or realize synchronous linkage of hooks to jointly hoist large heavy workpieces. Installed on the rails of double main girders, the lifting trolleys complete vertical lifting and transverse traveling of loads.
Product Advantages
Engineered for maximum energy efficiency, reduced maintenance costs, and higher operational productivity.
