This unit was designed to pneumatically clamp a drum and/or filter, lift and manually dump up to 350 lbs capacity. The hand wheel, for manual dumping, offers a 20:1 reduction on lighter capacities and a 40:1 reduction on the heavier capacities. As an option, we can incorporate two speeds. A high speed lift and a creep speed for accurate positioning. This is a competitive alternative to a pneumatic drum rotators.
