Crane Load Cell

The 20510 Crane Load Cell is an ultra-precision strain gauge-based tension load cell designed for crane weighing and tension measurement applications. It operates only in tension mode and is typically installed using a shackle at one end and a hook at the other.

Manufactured from high alloy tool steel with electroless nickel plating, it offers excellent resistance to shock, overload, and harsh industrial environments. 

The load cell is compact, rugged, lightweight, and portable, making it ideal for field operations such as crane load monitoring, towing force measurement, and rope tension measurement.

It is available in standard capacities ranging from 3 TF to 30 TF, with customization options available.

Frequently Asked Questions (FAQs)

1 What is the working principle of the 20510 Crane Load Cell?

It works on the strain gauge principle, where applied tension force causes deformation in the load cell body. This deformation changes the resistance of strain gauges, generating a proportional electrical output (mV/V).

2 Can this load cell measure compression?

No. It is designed only for tension measurement.

3 What industries commonly use this load cell?

• Crane & lifting equipment

• Shipyards & cargo handling

• Towing force measurement

• Material handling systems

• Tension dynamometers

4 What is the output signal?

• Standard analog output: 1.0 mV/V

• Optional outputs available:

• 420 mA

• 02 V
