✔️ Wooden pulley
🔸 You have seen these big reels mostly next to buildings under construction or industrial areas. Wooden pulleys are divided into three types, including one-way export pulleys, which are special for one-way trips, and pulleys whose middle material is made of steel.
🔸Using wooden pulleys, heavy wires and cables can be transported. These types of reels can also be used as a table. The material of the reel is also very important in protecting the wire and cable during transportation. Sometimes the wire and cable come out from around the reel, which happens due to the improper size of the reel in the process of winding the wire and cable inside it. The size and type of reel should be selected according to the weight, length and diameter of the wire and cable. If the reel is not suitable for the weight and diameter of the wire and cable, the possibility of damage to the wire and cable during transportation is very high.
