Case Studies & Testimonials - Ergonomic Lifting

1. Easy Arm® Replaces Manual Lifting at Reclamation Facility

Background

At a Michigan-based refrigerant company that specializes in reclamation, thousands of steel cylinders are processed each year. Each cylinder is weighed, recorded, and refilled. For many years, employees lifted and rotated each cylinder manually.

The Problem

With the heaviest cylinders weighing 80-pounds, it was a job few people could physically sustain. Employees were experiencing arm and shoulder pain due to the repetitive lifting. Some employees were also reaching far into cages to lift or drag cylinders out, so the potential for injuries was significant. The company’s president decided an ergonomic material handling solution could make their operation safer and more productive. Options across the industry were considered, from traditional overhead lifting systems to ultramodern exoskeletons.

The Solution

When the company’s president discovered the Easy Arm® Intelligent Lift Assist Device, the simplicity of its operation stood out – his employees would not need to undergo extensive training to use it. The Easy Arm® combines an articulating jib with a G-Force® device to create a user-friendly handling experience and natural load management. The G-Force® functions similarly to a hoist but is ergonomically designed for unweighting loads and precision placement tasks.

Four of the facility’s processing stations were outfitted with 165-pound capacity Easy Arms®. Moving cylinders became as simple as threading the system’s hook. Productivity increased, as well as workplace satisfaction. Employees are working longer hours and electing to work weekend shifts because they are not physically fatigued. The job is more accessible and appeals to many people. In the words of one employee, “Anyone can do it.”

2. Easy Arm® Makes Operators Feel Like Superman

Background

Van der Graaf (VDG) has been a leader in designing and manufacturing drum motors for belt conveyors since 1985. Over the years, their operations have expanded to include a 270,000 square-foot facility equipped with advanced manufacturing technology. A simple goal to create superior products drives all their operations.

The Problem

Every fifteen minutes, operators offload and load metal cylinders into an industrial lathe at VDG manufacturing headquarters. While there is a travelling bridge crane in the facility, it lacks the precision needed to move the cylinders and its large hook does not fit into the lathe well. Using this crane to move cylinders also disrupted other manufacturing processes.

The Solution

VDG wanted an intermediary system – one that was not as basic as a jib crane, but not as complex as a robotic cell. The Gorbel® Easy Arm® met and exceeded VDG’s expectations by seamlessly combining an articulating jib crane and intelligent hoist.

With the Easy Arm® system, VDG operators were able to enjoy the benefits of automation without sacrificing precision. Moving cylinders was faster and easier than ever. “You feel like Superman,” said their Operations Production Manager when describing the Easy Arm® handling experience.

The Easy Arm® also simplified the process, allowing operators to offload and load a cylinder without changing systems or hooks. Overall, VDG observed that the Easy Arm® optimized a crucial step of their conveyor drive production process and increased safety.

3. Moving Superchargers in the Automotive Industry with G-Force®

Background

In this automotive industry application, Cynergy Ergonomics designed a system to assist operators in the handling of superchargers during manufacturing/assembly through the packaging phase with a single lift assist device.

The tooling is designed to handle the superchargers with varying geometries and also orients the superchargers horizontally and vertically depending on which stage of the manufacturing process they are in.

The Solution

One system consists of a telescopic rigid mast manipulator using a Gorbel iQ G-Force in a nested trolley configuration; this operates in a double aluminum bridge Gorbel free standing workstation crane system. The Gorbel force sensing handle is utilized for raising and lowering control; the handle geometry wraps around the mast to facilitate operation from different positions as needed in the various manufacturing phases.

Another iQ G-Force feature is programmable virtual travel limits. This feature is used in conjunction with tooling mounted proxy switches to activate/deactivate preset travel stop elevations, placing the tooling in the exact position needed for pick and place operations.
