Single Pillar ATEX Drum Hoist for Steel Drums

ATEX Drum Hoist Description

DLM/100/2800/B/ATEX

This ATEX Drum Hoist is a single pillar post hoist that was designed to elevate a Steel Drum (464mm Diameter x 827mm High) to a height of approximately 2800mm before tipping it gradually through an angle of 50 degrees. The ATEX Drum Hoist was constructed from Grade 304 stainless steel and was bolted to the floor. Lifting with the ATEX Drum 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 drum was loaded at an angle of 10 degrees giving a total angle of the drum in the fully tipped position of 60 degrees. The drum was loaded at the ground floor and retained into the formed lift carriage by a retaining bar and toggle latch. As the drum approaches its full up position, it was tipped over using a mechanical cam to a total angle of 60 degrees. At the full up position, an end of travel pneumatic limit switch stops the lift carriage with a second end of travel pneumatic limit at the full down position.

The ATEX Drum 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 Drum Hoist has a Safe Working Load of 100 Kgs. The area in which this ATEX Drum Hoist was installed, was an ATEX Zone 1/21 IIC T4 area and all components and materials used and the design of the ATEX Drum Hoist conformed to the requirements of this ATEX Classification.

Pneumatic Control System

The Pneumatic Control System for this ATEX Drum Hoist was mounted in a Stainless Steel Enclosure fixed to the main column. The ATEX Drum 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.

Stainless Steel Infeed Gravity Roller Track & Ramp

In front of the ATEX Drum Hoist lift carriage there was a 500mm long x 600mm wide length of stainless steel gravity roller track, 125mm high. The rollers were 50mm diameter with sealed bearings and the base frame was from 40 x 40mm angle.
