Description
The Liftchain hoist is air-powered and designed to suit industrial
or mining applications. The Liftchain hoist can be hook-
mounted to a permanent mounting structure or any attachment
point capable of supporting the hoist rated capacity with an
adequate safety factor. Mining hoists are equipped with a
mounting arrangement in the form of a flexible chain link
connection between the top hook and the hoist body. Retractable
lifting handles are built into the hoist body.
The air supply line can be strung to the hoist using cable
hangers, cable trolleys or any festooning system that will ensure
the air line remains free of kinks or sharp bends and is protected
from being pinched or crushed by other equipment.
Liftchain hoists are driven by a lube-free gear motor which is
connected to a pinion shaft which in turn drives the planetary
reduction gear. The output from the planetary reduction gear
drives the load chain sprocket. The pinion shaft from the
planetary reduction is also coupled to the brake discs. The brake
is engaged at all times, until the hoist is powered in either the
raise or lower direction. System pressure acts on the brake
piston to release the spring-applied brake. The brake and gear
components run in an oil bath.
The optional overload protection kit is completely integrated
into the motor body.
Reversible Pulling Applications
Using either a single or a double chain fall, load hooks can be
attached to both ends of the chain. Refer to Dwg. MHP1435. If
the motor is equipped with an overload device and/or emergency
stop, both will function while paying out or hauling in a load.
