In order to overcome the disadvantage that a general trolley can not easily carry heavy objects from the ground to a vehicle, the appearance of a lifting beam trolley not only allows the heavy objects to be moved from the ground to the vehicle with relatively low effort, If the trolley is speaking in terms of price, it would appear to be relatively inexpensive, and in the case of its material parts, it would be easier to obtain it. Using this trolley also reduces labor damage.
On the lifting beam trolley, first of all, we actually found that it itself will be set directly on a base with a gantry frame, next, will be set in the frame above the base of the wheel, the frame The upper will be set up handrails, this time it will form a small cart.
Next to say, that is, the framework of the two columns inside the lower end of the contour hanging set up a weight platform can swing back and forth, and in fact the middle of the gantry frame is set crossbar, gantry frame top That is, there will be a crane.
In fact, the lifting mechanism on the lifting beam trolley will consist of the winch, the handle and the bicycle flywheel and the cable. In terms of the handle, the lifting mechanism will be fixed to one end of the winch to a large extent, Just one end of the capstan will be equipped with a simple clutch, in this case, in fact, that is, in order to achieve and fixed in the gantry frame flywheel coupling or separation, one end of the cable tied to the winch, and the other end will be heavy connection.
The simple clutch on the lifting beam trolley is composed of the capstan and the screw that passes through the capstan and the flywheel of the bicycle. On the lifting beam trolley bicycle flywheel, the internal ratchet self-locking structure, which is actually a national standard parts. When using it, the lifting beam trolley will be pushed next to the heavy object, the heavy object platform will be put back, and then the heavy object will be tied with the cable so that after the heavy object completes a series of operations, the heavy object is also lowered I've done my job
