Single Pillar ATEX Post Hoist

ATEX Post Hoist Description

PHM/160/2800/B/ATEX

This ATEX Post Hoist is a single pillar machine that was designed to elevate an 800 x 900mm Platform to a height of 1745mm in an ATEX Pharmaceutical environment. The ATEX Post Hoist platform was loaded at low level and then lifted to the required height to allow easy access for the Operational Personnel from the adjacent access platform who rotated the platform into position to enable the product to be dispensed easily into a mixer. The ATEX Post Hoist was designed to be bolted to the floor. Lifting with the ATEX Post Hoist was accomplished by the rotation of a precision ball screw contained within the main column. The motor was a pneumatic air motor complete with a braking system so that when the air supply was removed the raised carriage is stopped immediately.

The ATEX Post Hoist was manufactured from Grade 304 Stainless Steel throughout and the finish was suitable for use in a pharmaceutical environment. The surface finish was a fine polish which is often referred to as Dull Polish or 180 Grit and the ATEX Post Hoist has a Safe Working Load of 160 Kgs. The area in which this ATEX Post Hoist was installed, was an ATEX Zone 1 area and all components and materials used and the design of the ATEX Post Hoist conformed to the requirements of this ATEX Classification.

In addition to the hoist platform, the main column supported a lifting arm which was located on a rotary spigot at the top of the column. This lifting attachment was used for lifting the mixer blades into and out of the mixing vessel. The lifting beam had a separate pneumatic motor controlled from the main pneumatic control panel and a Safe Working Load of 75Kgs.

Pneumatic Control System

The Pneumatic Control System for this ATEX Post Hoist was mounted in a Stainless Steel Enclosure fixed to the main column. The ATEX Post Hoist can be operated in both directions from the control panel using dual push buttons which must be held for the machine to move. The control panel incorporated the use of air pilot operated ATEX valves to control the lifting operations. The limit switches were pneumatically operated, to detect 'Full Up' and 'Full Down' positions. All pneumatic tubing was antistatic and suitable earth bonding points were present.
