Key feature

1. Lengthened elevator boom effectively expands the working space and the employed rigid double drag rods result in a lighter deadweight, lower windage as well as the small section. This structure and technology led the field of this trade nationwide.

2. The L-hoisting structure employs a planet-bevel gear to regulate working speed. This unique design can effectively expand the wire cable’s capability, stabilize hoisting the underloading while at the high speed and take position correctly while elevating the oveloading at the low speed.

3. Side and freestanding cab is wide-field with enough inner space where the ganging control console and a soft chair to be equipped for a convenient operation.

4.Contour design employs an international style, pleasing to the eye.

5. As for all steel structures, the employed carbon dioxide welding can ensure them to be well-set.

6. Following safety devices are equipped: deboosters for weight, force moment, amplitude, height and gyration, respectively; Safety device against wire rope’s failure and groove skipping.

 

7. Both monolithic foundation and weighting mold are available for the rood beam’s choice.
