Plastic Tackle Pulleys (Plastic Elevator Wheels) are the pulleys which transmits the movement from the lift motor. They are used above and below the cabin as 1/1 or 2/1 hanger.
Deflection plastic pulleys or diverting elevator wheels are the pulleys which enable the rope to reach to weight properly by changing the direction of the rope.
Hydraulic pulleys are the plastic wheels which provide the transmission between the cabin and hydraulic system and they are able to move in the same direction as another or opposite to each other.
Our GG 25 gray cast iron and GGG 50 nodular cast iron pulleys (Elevator Wheels) are used in tackle, deflection and hydraulic pulleys.
You can get them as set along with pulleys as Nodular cast and metal type.
