Equipment Loading and Transport Machine (Rotating Lift Cart)

Sigma designs and builds custom transport and loading/unloading machines for a large manufacturer of decentralized power stations

The “Rotating Lift Cart” designed by Sigma Design for a large manufacturer of decentralized power stations was created to assist fabricators and assembly technicians with moving their heavy test equipment from the final stages of the assembly line to the testing area, as well as assist with the loading and unloading of the equipment. The Rotating Lift Cart features an integrated scissor lift with a rotating table, allowing the equipment to be loaded from either side of the machine at heights from 12” to 30”.

The cart is driven using a Master Mover Electric Tugger via a custom coupling between the tiller and the cart. To help the operators load and unload the equipment, a DC Gearmotor-driven lead screw linear actuator is used to either pull or push the 800+ lb. equipment into or out of the testing enclosure. For the cart to be fully utilized when it is separated from the assembly line, a dual power solution was devised. When the cart is used on the assembly line, it can be powered from an AC drop at that station. When the cart is moving from station to station or moving away from the assembly line, the cart can be powered from the DC battery inside the Master Mover Tugger. This flexibility allows the scissor lift and actuator to always be functional, giving the operators more assistance in all parts of the factory.

New Design for the French Press G-M™

Customer: Glen Mills, Inc. NJ

Industry: Medical Laboratory Devices

Sub Heading: Sigma Design Company improves the design of a medical device to improve cell culture and tissue engineering capabilities for laboratories.

Sigma Design Company can be your partner in not only design but also in the manufacture of your new product. Consider the story behind the Glen Mills/Zellwerk Z®RP Reactor System” – a cell disruptor and high-pressure homogenizer. With the discontinuation of their previous French Press manufacturer’s production, Glenn Mills Inc. needed to find a company that could redesign and manufacture the French Press directly for them. They found this in Sigma Design Company. Working with the original design, which was based on a 60 year old medical device, Sigma reverse engineered and redesigned the machine to have more features, better aesthetics, and compatibility with all of the older system’s accessories. This new design incorporated many of the skills Sigma excels at including: tight tolerance machine components, hydraulics, circuit board design, material properties and finishes. With a newly designed product, Sigma Design Company manufactures and assembles these units in our NJ facility, providing immediate customer support, and a short lead time to our customers.

Sigma is also the manufacturer of the French Press G-M™
