Atabec Pumpjack Lock Out Tool

The Atabec Pumpjack Lock Out Tool’s patented technology is designed to improve worker safety, reduce costs, and reduce the environmental impact of operations.

It minimizes down time and optimizes operational maintenance, all while maximizing safety goals. Counterweights on most pumpjacks can weigh up to 10 tons. That weight, combined with momentum and pinch points, creates extreme danger to employees. Statistics indicate that every year one service employee in the U.S. is killed, and dozens more are injured worldwide while conducting pumpjack maintenance. Do not put your employees at risk – trust the engineered strength of Atabec’s Pumpjack Lock Out Tool.

Atabec’s simple-to-operate hand pump hydraulic lock engages and disengages from outside the danger area. With the hydraulic fork engaged, there is zero crank movement – even with no brake and full power applied to the unit. One hundred percent non-toxic and environmentally friendly fluid is utilized in its closed loop system.
