Overview
ONLYWE Crane QDX series double girder overhead cranes provide special load capacity for a low deadweight. Strong and agile, with lifting capacity(weight) can up to 100 tons, it is particularly good tool for general manufacturing, workshops, warehouse and other assembly lines. The load hook can be raised between the two crane girders(beam), which permit huge lifting heights can be make it.
This series of products is matched with CMG series wire rope electric hoists.
1. Design according to FEM1.001 and CMAA70 standards.
2. Low deadweight can reduce investment layout,improve the lifting height. 
3. Crane girders can be adapted to building structure needs.
4. Compact travelling hoist design, make crane have available height and space.
5. End carriages with torsionally rigid, welded box-section design.
6. To prevent the rail from gnawing, wheel group with adjustable structure.
7. Based on different working conditions, overload limiter, height limiter, stroke limiter, and other security measures are equipped.
8. Crane control can meet different application requirements: via radio control, pendant control or cab control (optional).
9. Maintenance platform and accessible crab facilitate maintenance of building interior fittings (optional).
10. Lifting capacity is non-standard customized, crane capacity can be produced according to clients’ needs.

Personalized configuration
Optional maintenance platform and accessible crab.
Control pendant suspended for separate travel on the crane girder with display for installation monitoring.
Optional radio control with display and push buttons.
Optional for radio control with power and signal transmission.
Optional for cab control.

Features:
l Optional radio control with display and push buttons.
Optional radio control with power and signal transmission.
Optional cab control.
l Effectively braking, smoothly moving, long service life.
l Crane spare parts with high safety and reliability.
l Crane is controlled by frequency conversion Three-In-One mechanism with, can reduce the noise.
