Product Description
The elevator counterweight is placed in the middle of the elevator counterweight frame to adjust the weight of the counterweight, which can be increased or decreased. The shape of the elevator counterweight is a cuboid. After the counterweight iron block is put into the counterweight frame, it needs to be pressed tightly with a pressure plate to prevent the elevator from moving and generating noise during operation.
The function of the counterweight is to balance the weight of the car. There is a traction wire rope connection between the car and the counterweight frame. The traction wire rope is driven by the friction generated by the traction sheave and the counterweight to move the car up and down. For the traction structure elevator, the counterweight should not be too heavy, nor should it be too light. It should be commensurate with the weight of the passenger and load car side. That is, the balance coefficient of the elevator should be between 0.4 and 0.5 according to regulations, that is, the weight of the counterweight and the weight of the car plus 0.4 to 0.5 times the rated load of the elevator.
The existing elevator counterweights are mainly divided into cast iron counterweights, composite counterweights and steel plate counterweights. Among them, the cast iron counterweight is made of cast iron as a whole, and the price is relatively high; the composite counterweight is made of 0.8mm iron sheet, and the filler is filled with cement, iron ore, iron powder and water evenly in the shell by stirring. ; Steel plate counterweights are mainly cut from steel plates, and have been sprayed on the outer surface, with various colors and thicknesses ranging from 10mm to 40mm. The cost is the highest among counterweights. The steel counterweight has high density and small size, which can significantly reduce the size of the counterweight and the height of the counterweight frame, which is very helpful to reduce the size of the hoistway and the height of the top, and the cost is also high. Under the normal size, the surplus size is reserved, and the composite counterweight can be used, or the composite and steel plate can be mixed and matched, which can reduce the cost.
