Application: The cup lifter is designed to assist in the demolding of cast products. Utilizing pneumatic suction cups the cup lifter used with a gantry or bridge crane, assists in reducing the effort required to demold cast products, such as panels and tubs.

The process of demolding large, heavy panels from their molds can be effortlessly accomplished with these Panel Lifters. The unit’s four large suction cups are lowered to the panel and attached by switching on the unit’s two vacuum pumps. Following slight lifting to attach safety straps, the unit is activated to lift the panel up and away from the mold and over to a waiting conveyor for finishing.

Four Cup Lifters

The 4-Cup Lifter utlizes 4 large suction cups, and includes two vacuum pumps to produce a strong vacuum required to lift heavy cast parts. A push on the hoist control button lifts the panel just enough to secure safety straps which hold the panel in the event of accidental shut-off of the system while lifting is in progress. With the straps in place, the button is again pushed to lift the panel up and away from the mold and over to a waiting conveyor for finishing.

The 10' unit is equipped, as mentioned, with four suction cups operated by two vacuum pumps. Each pump operates independently and activates two of the suction cupls, providing an important safety back-up. Should one pump fail, the second pump (and two other suction cups) would remain active to keep the panel in place.

The 4-Cup Panel Lifter is a tremendous benefit to the industry in an age of liability concerns over employee health problems, worker safety and Worker's Compensation claims. Let the 4-Cup Panel Lifter do the heavy work on your panel molds... its been engineered to take it!
