Hooklifts are mounted on heavy duty trucks to enable haulers to change out flatbeds, dumpster bodies, and similar containers; primarily used in conjunction with tilt frame bodies and specialised containers, generally designed for the transportation of materials in the waste, recycling, scrap and demolition industries. The Hooklift system employs a series of hydraulic rams to hook, lift and hoist the container onto the chassis of the truck. There are several configuration options, and strict guidelines which must be followed to ensure that the container is secured on the truck in transit.
