QDE Double Girder Trolley Overhead Crane
Description
The Double Girder Trolley Overhead Crane (QDE Model) is an advanced heavy-duty lifting solution engineered for complex, synchronized, and long-load material handling. Built with two independent hoisting trolleys along the main bridge, this double girder trolley overhead crane enables precise multi-point lifting and smooth load rotation in demanding industrial environments.
Core Technical Features & Engineering Advantages
Utilizing a rigid double-box main girder framework for superior load distribution, key highlights include:
-
Dual-Trolley Tandem Lifting: Two independent trolleys operate separately or in tandem to transport long pipes, steel plates, and precast concrete beams.
-
VFD Speed Control & Control Options: Offers stepless variable frequency drives alongside wireless remote, pendant, or operator cabin control.
-
Heavy-Duty Construction (A5–A7): Engineered for high duty cycles, exceptional structural rigidity, and resistance to frame deformation.
-
Integrated Safety Systems: Fully equipped with dual limit switches, anti-collision sensors, overload limiters, and fail-safe safety brakes.
With multi-point rigging flexibility and low maintenance downtime, the double girder trolley overhead crane is an ideal lifting system for steel mills, shipyards, precast yards, and heavy manufacturing bays.
