Wheel Hubs

Operators were lifting hubs out of a crate and holding the heavy part, while trying to align the wheel stud holes and place it on the wheel. This procedure required two operators and still resulted in back injuries.

Wheel & Swing Drives

Operators were using a chain and hoist solution to transfer parts. It was deemed an unsafe environment with several dropped parts. Accurate placement in workstation positioners and pallets could not be achieved. Operators were not meeting cycle times with prior handling method.

Tire Assemblies

The tire assembly needs to be oriented so that the hub centerline is parallel to the centerline of the axle. there is a close fit between the hub ID and axle OD. The tire assembly must be rotated to align the hub key with the axle keyway. Thus, the tire assembly is lifted, pitched, swiveled, and rotated during installation onto the axle. An overhead hoist with a sling or C-frame lifting device was used for lifting; however, this method lacked control and safety.

Semi-Tractor Seats

Seat weight increased beyond single operator capability.

Oil Pan

The system capacity rating must be able to accommodate larger oil pans that may be manufactured at a future date. The radial reach and capacity requirements create significant moment loads. Work Cell contains obstructions and low headroom.

Nut Setter

The different angles and locations of the bolts and a restricted work cell area. A total of four units must be located in the same area with each having a different nut setter doing a different task. The customer would like to reduce the cycle time and eliminate end-effector changes during the assembly process. The ultimate goal is to reduce shock absorbed by the operator.

Hydraulic Swing Cylinder

Workers had to lean over the chassis to install the cylinders resulting in several back injuries.

HT Converter Housing

Two machining centers in a 16′ x 16′ work cell. One operator is expected to keep the manufacturing process at peak efficiency while manhandling light, but rather large 20″ diameter parts. The safety and ability of the aging workforce to maintain the required cycle time parameters of the work cell led the end-user to seek an ergonomic solution to this material handling problem.

Glass Panels

Safe3ly pitch heavy glass panels varying in size, weighing up to 150 lbs. up to 110°, from vertical to horizontal and rotate through the pitched horizontal axis to line up holes for installation.
