Handling Issues
The client’s handling cycle consists of lifting a stack of metal plates. When the stack arrives at the client’s facility, they are sitting vertical in a wood crate at about 4” from the floor. The stack is lifted from the vertical position, rotated 90° and placed on a cart to be sent to the machine room where additional machining and finish work is performed. After machining, the plates are placed back on a cart, moved back to the packing station where the cycle is repeated in reverse. The operator was having to handle one plate at a time when moving them from the crate to the cart which was taking an unsustainable amount of time.
The Solution
ASE specified a hoist-based air powered ID gripper tool designed to be supported from the client’s existing overhead crane. The hoist-based tool (HBT) included gripper arms intended to grip the stack from the inside dimension and to lift & rotate the stack from vertical to horizontal. The tool utilizes compressed air cylinders to achieve the grip and rotation functions. Attach and release controls are located on an articulated hand assembly that provides additional ergonomic value when lifting loads close to or at floor level. The HBT tool enabled the safe & precise handling of each stack of plates and met the client’s requirement for a quick and easy handling solution. HBT tools are available in capacities ranging from 30-lbs up to 10,000-lbs. Tooling options include ID expanding mandrels, OD gripper pads (pictured below), cradles, forks, hooks and scissor type grippers. This ergonomic lift assist technology reduces fatigue, improves safety and increases productivity.
