Suspended working platform has been widely used in related industries in our country, and it has also been greatly improved and improved. But in terms of technology, manufacturing materials and processing technology, there is still a step forward space. If hoisting machine, lifting weight and self weight ratio can be bigger?. In particular, the lifting capacity of the 800kg hoist is only 85kg higher than that of the 630kg hoist, but its weight is increased by nearly twice.
At present, most of the work platform of the building basket on the construction site is welded by 2mm thin-walled tube. The structure has been used for many years and proved to be reliable in quality. But there are some problems which should be paid more attention: one is the thin wall, bolt fastening parts of square tube combination platform, although some manufacturers with a large diameter flat pad, taking into account the current quality of operator, which needs to be improved.
Can the 630kg hoist increase the 80kg lift by some minor modifications?
Can some overload protection and misoperation prevention be added to the electrical circuit? These are already necessary facilities on the tower crane.
The second is the connection of the floor part, in order to install the bolt easily, the long hole is used. M12 bolt with 14x20 long hole, even with flat pad, as a high-altitude operation of mechanical equipment, it is not desirable. I hope entrepreneurs who are interested in a higher level can play the role of pacesetter and leader in this field, so that China's electric gondola will have a new break through in quality.
