The LTP 61 truck and bus assembly tool from Atlas Copco Tools & Assembly Systems is twice as fast as its predecessor, the LTP 51, according to the company. The standard shutoff nutrunner with a high-speed twin motor improves tightening by building up continuous torque to produce improved quality in the tightening phase without compromising the process during the rundown phase. Features include improved accuracy and productivity as well as an ergonomic design. Exhaust air is piped through the handle into a hose, minimizing noise from the pneumatic system and decreasing noise generated by the actual process. Reaction force is handled by a torque-reaction bar, minimizing wrist and arm strain for the operator.
