Function
Operating principle
The wire rope hoist works by pulling the lever back and forth when the wire rope runs through the hoist. The wire rope hoist can be used for lifting,
pulling and tightening.
The wire rope hoist has two jaws that open in turns so that the wire will always stay tight and will not be able to loosen.
The safety shear pin on the wire rope hoist's lifting lever breaks at just above WLL to prevent overloading. 5 pcs of spare shear pins included in the
handle.
Procedure before use
Wire rope hoists inspection before use
A competent person should check the wire rope hoist visually and its workability before first use. By testing the wire rope hoist you make sure the
wire rope hoist hasn't been damaged or broken during its transportation.
Inspection before lift/pull
Before every use the hoist, wire rope, anchor sling and other lifting tools conditions have to be checked in case of any kind of damage. Also check
that the hoist's name plate is legiable. Any equipment or parts with defects must be taken out of service until it has been repaired or replaced. In ad-
dition, the jaw clamps function ability as well as the anchors durability is to be tested by lifting/pulling the load a short distance and then lowering it.
Wire rope inspection
Check the wire rope for deformation, bending, twisting, cutting of lines, corrosion, overheating etc. before use.
Eye sling hook inspection
Check the hook for deformation, notches, wear and corrosion or in case of any damage.
Wire rope specification
It is allowed to use only this type of wire rope:
∙ Steel core
∙ Grade 1770 N/mm
2
∙ Construction 6x19-IWRC
∙ Dry
Use
Open the wire rope jaw clamps so that the wire rope won't bend or twist.
Push the release handle on top of the wire rope hoist in a forward position until you hear the jaws open.
Push the wire rope through the wire rope hoist so you can see it from the other side. Pull as much rope as you need and then lock the wire rope by
pushing the release handle to a backwards position.
Place the lever handle extension either in the front or back peg depending if you want to lift or lower the load. Now the wire rope hoist is ready for
use.
Take the anchor pin out and attach hook, shackle, sling or some other tool needed to connect the hoist to the anchor point.
Attention! Check the strength of the attachment point before starting to lift or pull.
Operating the lifting lever back and forth will make the wire move through the wire rope hoist and tighten. Moving one of the levers you can make
the wire rope move in or out.
When finishing the use of the wire rope hoist pull the wire out by pushing the release lever on top of the wire rope hoist into a frontward position so
that the wire rope get released. Clean the wire rope before releasing it through the wire rope hoist so that no dirt will get into the wire rope hoist.
After removal of the wire rope push the release handle back to the backwards position so that the spring relaxes.

When attaching the wire rope hoist make sure that the person who is using the wire rope hoist won't be put into dangerous situations from the load
or attaching the wire rope hoist.
Mount the wire rope hoist in between the anchoring point and the load so that the wire rope hoist is set in the same direction as the wire rope and
so the wire rope moves straight through the direction of the pulling direction.
In an indirect pull use only strong enough wire rope blocks.
Using lifting slings or lifting tools, make sure that they have at least the same loading capacity as the wire rope hoist that is being used.
Make sure that the anchor pin is fully locked in place with a spring pin.
Warnings
Before use make sure all the wire rope hoist's screws are tightened. Also check the product's common condition and that the handles move freely.
Check that the wire rope is clean. If the wire rope is damaged, the wire rope hoist won't work properly and must be replaced immediately.
Only use one lever at the same time. Never touch the release handle when the wire rope hoist is loaded.
Don't pull on the lifting lever too hard, since the overload safety pin will break. Don't use homemade overloading safety pins on the wire rope hoist!
