10t qd remote control double girder overhead crane with grab

Product Details

The qd winch bridge crane is a lifting equipment that is horizontally framed over the workshop, warehouse and material yard for material lifting. Because its two ends are located on tall concrete columns or metal supports, it is shaped like a bridge. The bridge frame of the bridge crane runs longitudinally along the tracks laid on both sides of the elevated frame, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery for bundle lifter, pipe lift, etc. with a wide range of applications and a large number.

Feature description

Lifting trolley: It consists of a lifting mechanism, a trolley operating mechanism and a trolley frame. The lifting mechanism includes a motor, brake, reducer, reel and pulley block. The motor drives the reel to rotate through the reducer, so that the steel wire rope is wound on the reel or lowered from the reel to lift heavy objects. The trolley frame is a frame that supports and installs components such as the lifting mechanism and the trolley running mechanism, and is usually a welded structure.

Box structure:

The box-shaped double beam on the right track is a basic form widely used. The main beam consists of upper and lower flange plates and vertical webs on both sides. The trolley rails are arranged on the center line of the upper flange plate. Its structure is simple. It is convenient to manufacture and suitable for mass production, but its own weight is relatively large.

The cross section of the off-track box-shaped double girder and the off-track box-shaped single main girder are composed of upper and lower flange plates and main and auxiliary webs of unequal thickness. The trolley rail is arranged above the main web, and the short The stiffening plate can be omitted, and the off-track box-shaped single main girder is replaced by a wide flange box main girder instead of two main girders. The dead weight is small, but the manufacturing is more complicated.

Drive mode of beam overhead traveling crane:

Centralized drive, that is, a motor drives the long drive shaft to drive the active wheels on both sides.

Driven separately, that is, the driving wheels on both sides are driven by an electric motor.

The "three-in-one" drive mode is a combination of brake, reducer and electric motor.
