Atlas Copco ErgoPulse Nutrunner cuts assembly time by half


For more than 50 years, Ruthmann in Hochmoor, Germany, has produced truck-mounted platforms with a focus on quality. For the assembly of the turntable – the connective link between wheels and hoists – Ruthmann has tested a number of assembly tools. Pneumatic impact wrenches were too noisy and inaccurate, electric impact wrenches were faster but too big and inaccurate. Recently the company found that ErgoPulse tools - EP12 PTS and EP 14 PTS - perfectly meet the tolerance requirements.

Industry foreman Johannes Thesing was amazed by the advantages provided by the ErgoPulse tools. “We are impressed by the essentially faster, more accurate, lightweight and quieter ErgoPulse tools without reaction force”, explains Thesing.

Each turntable is assembled with 40 to 80 joints that reach torques of up to 240 Nm. The investment in a new compress air device to run the tools was easily justified. By eliminated the need to retorque with a torque wrench, spot checks are now sufficient and assembly is made in half the time.
