DON’T FORGET YOUR TOOL BALANCERS

TECNA TE9356 and TE9357 stainless steel cable zero-gravity balancers FOR SALE at Weld Systems Integrators. TE9356 and TE9357 balancers feature a double aluminum housing and suspend the tool on a stainless steel wire cable / rope. TECNA zero-gravity balancers use a conical drum, calibrated to provide constant upward tension that counterbalances the weight of the suspended tool or load. This achieves a floating neutral support where gravity is essentially negated, allowing near-effortless positioning, while maintaining the operator’s last position.
