Case Study #7

Application: HVAC Coil Handling Manipulator Lift Assist

Problem:  Customer was lifting heavy coils coming off a coil bender by hand. The parts weighed up to 90 pounds which required 2 operators to pick up the parts to load them onto the base of the HVAC unit. This required the operators to lift the heavy coil over their heads in order to set down the part. This application was a constant source of shoulder and back injuries.

Requirement:  Allow one operator to lift the coils and load onto the base unit without heavy lifting or awkward working postures.

Solution:  Using a pneumatically powered manipulator, we were able to grip the coil coming off the bender and lift them up, over, and back down onto the frame of the refrigeration unit. Because the coils were easily damaged, large gripper pads were utilized to in order to spread out the grip force. Because the part had to travel close to 30 inches in order to load onto the base, the lift assist was equipped with two sets of controls. This allowed the operators to consistently maintain a good ergonomic position at pick up and set down.

weighing up to 90 pounds. The lifting device has two sets of controls to
consistently maintain good ergonomic posture.

Result:  The customer was able to lift the part with one operator safely. The manipulator helped
maintain task time, reduce injury, and free up an operator in the area to help out with other areas
of production.
