HD Electric Hoist Crane

HD Electric Hoist Crane have such design concepts as the limiting distance is minimum from hook to wall, and headroom is the lowest, which makes cranes work more close to the front, and lifting height more higher that increases effective working space of workplace.

Product Type: HD
Lifting Capacity: 1~30t
Span: ≧6m
Lifting Height: According your demands
Working Class: A5
Ambient Temperature: -20~40℃

OVERVIEW

European style single girder overhead cranes have the design concepts of small dimension, light dead weight and so on. Compared with traditional crane,European style single girder overhead crane has the minimum limiting distance from hook to wall, lower headroom and higher lifting height. With these features, the European style single girder overhead crane could provide the workplace with more effective working space. As a result of it, the workplace could be designed smaller than before but with more functions. In addition, the wheel pressure is also decrease because the dead weight than before. A huge amount of money could be saved from the initial construction investment, long term heating fee, air conditioning and other maintenance fee. From the above, European style single girder overhead crane is a advisable choice for the client.
