Design; Functions; Important Components - HADEF 59/18 Installation, Operating And Maintenance Instructions

DANGER!
It is not permitted to use the unit in an area at risk from explosion!
4.2

Design

HADEF ratchet lever hoists are compact hoists
with suspension hook for stationary use.
4.3

Functions

The load is lifted, lowered or tensioned by operating the lever. The load pressure brake prevents automatic
lowering of the load.
NOTICE!
If used "overhead" or "lashing" undefined forces may appear. We recommend to use a hoist with
slipping clutch for these cases.
NOTICE!
The best protection against functional failures in case of extreme environmental impact is the regular use of
the equipment.

Important components

 Gear
Gear components are made of high-quality material.
 Load pressure brake
Holds the load in any position.
A new brake system is used for the hoists. Brake
discs have sintered brake linings which, when
used appropriately, makes them wear-free for
lifetime of the hoists.
According to DIN 13157 lifetime is 1500 operating
cycles (lifting/lowering movements) with 300 mm
lift with nominal load.
 Housing
The housing is made of steel plate.
 Load chain
According to EN 818-7-T high quality chain. All components match precisely to each other. Therefore please
only use original chains.
 Load hook with safety catch.
Forged steel. Rotating, this facilitates attaching the load and avoids twisting of the chain.
 Free-wheeling of chain
For pulling through of the uncharged chain.
