Special Load Cells Model WTB

Special Load Cells Model WTB


WTB cable tension type load cells are designed specially for cranes and lifting systems. They are mounted on the permanent cables of the lifting mechanism and they sense the load exerted on the cables.

With its stainless steel construction as well as its welded strain gauge area, WTB is protected to IP68 standards meaning that it is fully resistant to dust, water and chemicals.

WTB load cells provide overload control for such lifting machines as cranes and elevators and measure the weight of the load being lifted.
