HEL4-F-SRC. All mechanical automatic clamping mechanisms handle from one to four drums at a time without any hydraulic or electrical connections to the lift truck. Ideal for palletizing drums or unloading trailers. Simply position the center guide over the four drums, lower and lift. Once the drums are gripped, the clamping mechanisms safely secure the drums in place for transportation over dock plates and other unlevel surfaces. To release the drums, fully lower the drums onto a pallet or floor, then elevate the center guide upward. 2000 lb. capacity per drum. FOB Shipping Point.
