Pin Type Load Cell

Pin Type Load Cell (Load Pin)

Stark Embsys manufactures high-strength Pin Type Load Cells (Load Pins) engineered to replace existing structural clevis pins, shackle pins, or sheave axle pins in overhead cranes, winches, and marine lifting equipment. Internal strain gauge bridges sense shear force directly within the pin body without requiring structural redesign.

Manufactured from high-tensile stainless steel or alloy steel with IP67/IP68 sealing, our load pins offer reliable overload protection and tension sensing for heavy-duty lifting and rigging operations across India.

Pin Type Load Cell Stark Embsys

Key Features

Direct Structural Replacement

Sheave axle pin load measurement.
Measures resultant cable tension forces across pulley sheaves in mining and construction hoists.
Offshore marine winches and mooring lines.
Submersible IP68 design tracks cable tension in marine environments.
Hoist limit switches and structural safety monitoring.
Prevents catastrophic crane overload accidents by interrupting hoist power when safe limits are breached.

Why Choose Stark Embsys Pin Type Load Cell

  • Seamless Integration: Replaces existing pivot or sheave pins without modifying mechanical structures.
