The Hanningfield Uni-Hoist HEM (Hoist Electric Mobile) is an electric powered, portable lifting device for the handling of containers, drums, IBCs etc. The maximum SWL (safe working load) of the Uni-Hoist HEM is 250kg.
For portability, the hoist and controls are mounted to a stainless steel frame with 4 x non-marking, anti-static castors (2 x swivel, 2 x swivel and brake). This enables the hoist to be used in multiple process rooms, requiring only a three-phase electricity supply in order to operate.
An under-slung electric motor is used to drive the lifting mechanism (lead screw or chain). The motor and gearbox has a removable cover for ease of access for maintenance. The hoist can be supplied with variable speed drive and control system for fast and slow lifting (slow lifting is designed to be used for the accurate docking of the load, with improved accuracy for positioning and manoeuvring). The hoist can be supplied with various sensors and limit switches to prevent over-travel or function to a pre-set sequence. ATEX versions of the Uni-Hoist system are available for use in hazardous area applications.
As standard, the hoist column and mobile frame are manufactured from 304 stainless steel (1.4301), with all exposed materials manufactured from FDA compliant materials such as polyacetal. External surfaces (including welds) are finished to 150 grit (Ra <1.06).
