Manlift For Hazardous Environment Announced

Chamberlain M a n u f a c t u r i n g Corporation has announced a first for self-propelled aerial platforms -—a unit designed for use in hazardous environments. The new machine is the latest addition to the large and growing Manlift® line of platforms produced by the company. It meets National Electrical Code requirements for use in Class I, Division I, Group D hazardous locations.

The new model is designated MSM25BEP, and is a pneumatically controlled, electrically powered scissors lift. Working height is 25 feet, with a 1,250-pound-lift capacity. The machine is fully operable by one person on the platform, and standard features include three speeds forward and reverse, automatic d r u m - t y p e brakes, and modularized control and drive systems for easy maintenance.

Work platform size is 42 by 67 inches. When .fully retracted, the machine is 75 inches long, 42 inches wide and 52 inches high. Nominal weight is 3,170 pounds. In addition to meeting NEC requirements, the MSM25- BEP is designed, built and tested to U.S. ANSI and Canadian CSA specifications.

NEC requirements are met by use of a unique pneumatic control system, powered by compressed carbon dioxide. Electrical components in the control system are minimized, and are housed in a Certified explosion-proof container.

All functions (drive and lift) are hydraulic, with a 5-hp 36-volt d-c explosion-proof electric motor driving the hydraulic pump. Power is supplied by a 36- volt battery pack housed in rollout drawers that are locked to prevent access in hazardous areas.

The only function that must be performed in a "safe" area is battery charging. This is done with a built-in automatic charger.

The MSM25BEP is suitable for use in shipyards, refineries, or other areas where fire or explosion hazards may be present.

Chamberlain also advises that the MSM25BEP system is adaptable to other models in the Manlift line. These include two scissors lifts, with working heights to 42 feet and capacity to 2 tons, and five telescoping booms, with working heights to 66 feet and capacities to 1,000 pounds.
