DQCRANES FEM standard single girder overhead crane for sale

Electric Hoist %&&&&&%

FEM standard single girder overhead crane overview

This series of products is matched with ND series electric hoist.

1. Design is based on FEM and CMAA70 standards.
2. With optimizing design and low headroom, the crane height is greatly reduced, to achieve higher lifting height under the same plant height.
3. With optimizing design and low wheel pressure, the crane height is greatly reduced, to achieve greater lifting capacity weight under the same strength of the workshop.
4. Wheel group with adjustable structure, to prevent the rail from gnawing.
5. Crane is controlled by Three-In-One mechanism with frequency conversion, to reduce the equipment noise.
6. Overload limiter, height limiter, Stroke limiter, photoelectric limiter and other security measures are equipped according to different working conditions, crane black box with recorded analysis functions can be added based on the customer requirements.
7. Lifting capacity: 2~20 t, non-standard customized crane can be produced.

European and Traditional Crane Comparison

Due to the designing concepts, European style single girder overhead crane has the features of small dimension, light dead weight, minimum limiting distance from hook to wall, lower headroom and higher lifting height, etc. Comparing with traditional overhead crane, European style single gird overhead crane has the advantage in the following ways:

• Firstly, European overhead crane could provide more effective working space than traditional crane does.
• Also, European overhead crane requires smaller workplace and has more functions. Thirdly, the wheel pressure of European crane is much smaller than the traditional one because of light dead weight.
• Lastly and most importantly, European crane could save a substantial amount of money, spent on initial construction investment, long term heating fee, air conditioning and other maintenance fee.

All in all, European style single girder overhead crane is a good choice for your material handling.
