Weasler yokes are made to withstand robust conditions, and engineered for a precise fit. Weasler’s Shear Pin Yoke features a pin (bolt) that extends through the yoke and if broken during operation will spin. The compact, efficient design disconnects the power source from the drivetrain when overload occurs and helps prevent the generatation of damaging torque spikes or heat. Once the operator replaces the bolt, the machine can be restarted.

• Implement overload protection.
• Minimal maintenance.
• No damaging heat generation for higher productivity.
• Repeatable overload disengagement setting.
• Smooth disengaged operation, no damaging torque spikes.
• Reduces possibility of damage.
