  • Page 10: Technical Description

    TECHNICAL DESCRIPTION The MB 500/120 RACK AND PINION HOIST is a machine designed to elevates goods up to 300 kg. A motor-powered moving deck slides on a special vertical column up to 120 m in height. The vertical column is attached to the wall or support frame every 6m. The base (1) is made up of a welded tubular frame, at the end of which 4 worm screws (2) are installed to regulate vertical alignment of the machine.
  • Page 11 The motor drive unit (11) is made up of a welded tubular bar and section bar frame. It is fitted with a series of guide rollers. It is driven by a self-acting electric gear motor (12) that enmeshes on the rack of the vertical column (3) via a pinion,. An emergency brake (14) starts when (in descent) the normal operating speed is exceeded.

  • Page 14: Machine Transportation

    MACHINE TRANSPORTATION The machine is delivered completely assembled (base, initial column, loading deck) and equipped with fittings, fixed to pallets with metal straps; a set of modular elements of the column is packed under the base, on the same pallet. The other modular elements of the column are packaged (approx.

  • Page 15: Loading/Unloading Support

    LOADING - UNLOADING SUPPORT To make easier the loading or unloading of the lift on motor vehicles, some detachable supports can be optionally requested, which allows the operation to be carried out without using any other lifting devices. Two uprights (1), 1 left-hand cross-piece and 1 right-hand cross-piece (2-3) are required.

  • Page 16: Installation

    INSTALLATION The lift must be installed only by skilled workers authorised for operation. The machine must be installed on a floor able to bear the following loads relative to the height of the vertical column Column Machine Working Total height weight capacity load...
  • Page 17 Caution: Regular tightening of the 4 vertical column screws ensure the necessary operating machine stability. Periodically check they are tightened. Only use class 8.8 (12) screws. Check the vertical alignment of the column again in both directions and make the necessary corrections by always turning the worm screws on the base, and finally clamping after the operation.

  • Page 18: Assembling The Vertical Column

    ASSEMBLING THE VERTICAL COLUMN After installing the base of the lift, the modular elements of the column can now be assembled. For this purpose two operators may board the lift and operate as described in this section. !!! WARNING!!! While assembling the machine, never turn the deck, and keep it in the locked position.

  • Page 19: 14A. Emergency Brake Test

    14a. !!! CAUTION - EMERGENCY BRAKE TESTS !!! The test must be conducted about every 3 months and/or whenever machine assembled personnel trained in compliance with the guidelines outlined below: To conduct the test the following conditions must be met: The machine must be firmly secured.
  • Page 20 If you are in the assembly stage, take the following steps: CAUTION: Load at most 3 vertical column modules on the deck. The operators on the deck must always work with their safety belt fastened to the deck to ensure they are suspended if they slip off. Raise the deck up to the top limit of the pre-assembled column, lower the guard (1) and couple the new module, making sure with utmost care that the screws are tightened.
  • Page 21 !!! CAUTION!!! Should the electric power supply fail while assembling or disassembling the vertical column and consequently the deck stops at a height with persons on board, the lift can be lowered by operating the motor brake: TAKE THE RELEASE LEVER (1) SCREWED ON THE MOTOR CASING AND SCREW IT ONTO THE NEARBY HOLE.

  • Page 22: Standard Wall Mounting

    The wall mounting, that must be secured every 6 m., is used to vertically support the whole frame and is this a very important element of the machine. Therefore, very firmly tighten all screws and clamps and frequently check they are tightened properly. Warning!!! Not to interfere with the bolts, fasten the release lever (a) of the turning plate parallel to the deck wall.
  • Page 23 Place the element (1) by first loosing the screw (3). Then place the element (2) and adjust its distance. Fit elements (1) and (2) to a wall with wall-plugs or to a metal frame with clamps able to bear the indicated loads. Check the vertical alignment of the machinery. Loosen the screw (3) until it touches the pipe of the vertical column.
