Technical description

  • ADLER hand wall winches with brake control differ as far as the braking system is concerned from conventional wall winches with load pressure brake. The load is normally lifted by clockwise rotation of the hand crank and securely held in all positions by the brake control. Lowering of the suspended load only requires the hand crank to be pushed back by approx. 90°. The load is lowered at a controlled speed (centrifugal brake). A minimum payout weight in accordance with the technical specifications is, however, required. The stopper lifting device ensures that the winch operates almost noiselessly.
  • Power transmission is effected by means of spur gears with grease lubrication for ambient temperatures of up to 40° C. The drive and drum shafts are equipped with robust roller bearings. Re-greasing is required.
  • The wall winches are designed in accordance with drive mechanism groups 1Bm and certified by the inspection authority in accordance with the accident prevention regulations.
          WH 3: A- HZ II 47/ 83, WH 5: A- HZ II 48/ 83
          WH 10: A- HZ II 49/ 83, WH 15: A- HZ II 50/ 83
  • The hand crank radius is infinitely adjustable, e.g. on partial loads.
  • Cable payout is normally vertical upwards. Overhead assembly and cable payout downwards is also available, as is attachment in any other direction with the drum axle in the horizontal position. Maximum permissible pulling incline as shown in Ill. 1 and 2.
  • Cable attached by hole and threaded pin.

Special design available

  • Crank with collapsible handle
  • Upper guard
  • The drum is supplied as standard non-grooved, can however be supplied grooved (see Ill. 3-6). All drums have two cable fixtures.
  • Twin-cable, non-grooved designs as shown in Ill. 3 - 7 available.

Both cables are attached to the same drum flanged pulley and are wound from that point parallel onto the other flanged pulley. On this drum grooving arrangement the cable can only be wound on in the layer No.1. If two cable layers are required, the grooving should be in accordance with Ill. 5 and 6.

The cable is attached at the centre of the drum. From there the two strands in the first layer are wound onto the two flanged pulleys. In the case of the 2nd cable layer, the two strands run back from the flanged pulleys to the drum centre.

A separation bar located at the centre of the drum can be fitted for larger cable take-ups on twin-cable operation.

  • Winches are also available for special applications where opposite turning direction is required i.e. the direction of rotation for “lifting” is not clockwise but anti-clockwise. The cable is then also wound on the opposite side.
  • Approved for passenger conveyance.
  • Initial lubrication with cold-resistant grease up to - 40°C.
  • Equipped with roll-away lock - prevents the load from falling down in case of damage to the gearing (only on WH 15).
