Drum Handling System Description
This Drum Handling System was designed to lift a 205 Litre drum to a height of 1800mm.
Once at this height, the drum can be completely inverted and lowered into a docking
station. The drum was fitted with a conical sealing funnel with a manual shut off
valve at the end. Prior to lifting, the drum was clamped into the lifting frame
using a sprung loaded safety mechanism. This safety mechanism included an electrical
interlock that only allowed the Drum Handling System to be operated if the clamp
is closed properly.
Once at the raised position, the drum could be inverted through 180 degrees. In
addition to the vertical movement and the inversion of the drum, it was possible
to manually swing the drum lifting arm through an angle of 90 degrees. Therefore
once the drum is raised and inverted, it can either be swung over its docking station
or, if the docking station is mobile, it can be moved beneath the inverted drum.
In either instance once the inverted drum and receptacle were correctly aligned,
the drum was lowered to dock with the receptacle. Once in this position, the manual
valve on the drum funnel was opened to allow the contents of the drum to be discharged.
The Drum Handling System was constructed from Grade 304 stainless steel and was
designed to be bolted to the floor. Lifting with the Drum Handling System was accomplished
via a machined ball screw and lifting nut mounted within the lift column. The ball
screw was rotated by an electrical motor gearbox that caused the lifting frame and
drum to be raised and lowered. This raise and lower control was via dual ‘dead man’s
handle’ control. When the lift is at the full up position, the drum was inverted
by an electrical motor gearbox drive once again via dual ‘dead man’s handle’ control.
The electrical control panel was a stainless steel enclosure mounted to the hoists
main column. The operator push button station was mounted on a Rittal Support Arm
System which was fixed to the top of the main control panel.
Drum Handling System Application Story
This Drum Handling System was manufactured for a Pharmaceutical Processor to handle
drums of a stainless steel powder. The drums were lifted, inverted and rotated above
a Comil milling machine. The drum spout was lowered to dock with the Comil and the
powder discharged by opening a valve. Once all of the powder was discharged and
milled, the empty drum was lowered back to its wheeled trolley to be replaced with
a full drum.
