SAFETY INSTRUCTIONS

CAUTION!
Danger of brake release!
The load pressure brake can release due to vibration. The cable winch should not be used to secure loads! Do not remove the crank while under load!

• Danger of fatal injury! – Never stand under suspended loads!

• Risk of accidents! – The brake system can overheat during extended lowering of loads. No continuous operation!
  Maximum lowering duration 2 – 5 minutes depending on the load.

• Risk of accidents! – Do not operate the cable winch if the locking switch is damaged!
  The crank could otherwise be inserted when the braking function is switched off.

• Only use ropes for which the hook is firmly attached to the rope via a pressed rope loop. End connections according to EN 13411-3, with thimbles according to 13411- If not otherwise stated in the EN standards listed above, the rope connections must be able to withstand a force of at least 85% of the minimum breaking force of the rope without a break!

• Hook and connecting device (triangle) must offer 4-times safety with cables and straps. No permanent distortion is allowed under static load with 2-times the nominal load. At 4-times static load, bending open or deformation is permitted, however the load must still be securely held (see EN 13157). Alternatively, a hook acc. to EN 1677-2 with guaranteed safe working load must be used.

• Sharp edges! Damage from scrapes, crushing, cuts. Always wear work gloves.

• Observe the required breaking load when using a strap.
  The breaking force of the stitched strap must be at least 7 times the specified tensile force in the lowest cable position.

• Do not knot together ropes / straps.

• Do not expose straps to acids or bases.

• Use a cover to protect straps from moisture and constant solar radiation.

• Do not exceed the tensile forces specified in the technical data.

• Always used non-twisting or low-twisting ropes for lifting a freely suspended load that could rotate during the lifting procedure!

INSTALLATION

Mounting the crank
**** The safety screws must lie over the recess on the hex connection (1/X)

1. Tighten the safety screws.

CAUTION!
Only use ropes for which the hook is firmly attached to the rope via a pressed rope loop.
** When under load, at least two cable windings must remain on the drum. Mark the cable end with a colour.
Mounting the cable**

1. Insert the steel cable from the inside to the outside through the oblong hole in the cable drum (2-1).

2. Insert the cable end with a large loop into the clamp and lightly tighten the hex nut (3).

3. Pull the loop back to the clamp and tighten the hex nut with a maximum of 10 Nm.

4. Wind up the cable by two windings.
   To do so, turn the crank in the “Lift” direction.

5. Mark the cable end with a colour (5-2).

Mounting the strap (option)
Our winches can optionally be used with a special
CAUTION!
Risk of accidents!
The breaking force of the stitched strap must be at least 7 times the specified tensile force in the lowest cable position.
** When mounting the strap, please note: – Always turn the crank in the “LIFT” direction.
Mounting the strap**

1. Push the AL-KO insertion element through the strap loop (4-1) and secure with a washer, serrated washer and screw (4-2).
2. Wind up the strap by two windings and mark the strap end with a colour.

Deflection pulleys
The minimum diameter of the deflection pulleys must be 12 times that of the cable diameter.

• Example:
  • Cable thickness Ø 7 mm
  • Deflection pulley Ø 84 mm

OPERATION

CAUTION!
Danger of brake release!
The load pressure brake can release due to vibration.
The cable winch should not be used to secure loads!

• Danger of fatal injury! Never stand under suspended loads!

• Risk of accidents! The brake system can overheat during extended lowering of loads. No continuous operation!
  Maximum lowering duration 2 – 5 minutes depending on the load.

• Check braking function of the cable winch.  There must be a clicking sound when turning in the “lifting” direction!

• Check the rope / strap for damage and replace if necessary.

• The rope / strap should not be run over sharp edges.

• When winding up the rope / strap without a load, keep it under a slight tension. For proper braking function, a minimum load of 25 kg is required.

• Only wind up a cable/strap under load to the point that there is an overhang on the flanged wheels of at least 1.5x the cable diameter (6).

Cable winch operation
Raising, pulling the load

1. Turn the crank clockwise.

Holding the load

1. Release the crank.
   The load is kept in the same position.

Lowering the load

1. Turn the crank anti-clockwise.
   The integrated brake prevents the crank from kicking back.

Deflection angle

When winding or unwinding, the deflection angle must not exceed 4° (5-1).

MAINTENANCE AND CARE

CAUTION!
Sharp edges!
Damage from scrapes, crushing, cuts. Always wear work gloves.
CAUTION!
Risk of injury
At the end of maintenance and repair work, reattach all covers with the original screws!
CAUTION!
Danger from wear!
The winch operator must check the cables/straps for wear before every use (DIN ISO 4309/BGR 500). Replace damaged cables/straps immediately.

1. The cable winch may only be inspected and maintained by trained technicians.
2. The brake mechanism was treated by the manufacturer with a special grease (Wolfracoat 99113). Other oils or greases are not permissible.

Inspecting the cable winch
The cable winch must always be inspected by a trained technician:

• Before initial start-up
• Every time the unit is remounted
• Once a year
  Trained technicians are persons with the necessary technical knowledge to inspect the work equipment on account of their professional training, experience and recent occupational activities.
  Please also note any other applicable national regulations.

Maintenance intervals

• When used regularly to 100% of the rated load: after raising and lowering by 100 m
• When used regularly to 50% of the rated load: after raising and lowering by 200 m

Perform the following tasks at these intervals:

• Inspection work
• Lubrication

Inspection work

• Check that the crank moves freely
• Check that the locking catch engages
• After raising and lowering the winch by 100 m, check the wear of the brake discs and the bonded brake pad.
  The brake pad must be at least 1.5 mm thick.

Oil and lubricating points
The winch is greased before delivery. Regrease the following points regularly:

• Drum hub
• Ring gear
• Bearing bushes of the drive shaft
• Crank thread

Grease recommended by AL-KO:

• OMV Whiteplex multipurpose grease.
• Staburags NBU12K multipurpose grease.

CAUTION!
