7. 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.
The vertical column (3) 1.50 m. in length, is made with latticed and welded tubular bars
and a rack. It must be bolted with appropriate securing bolts (4) every 6 m. to a support
wall or a frame able to bear the transmitted loads indicated in paragraph 15 on page 22.
The loading deck (5) consists of a welded sheet walkway on a support frame made of
section bars. The walkway is limited by a pair of fixed guards (6) along the longer sides
and two access gates are provided on the shorter sides equipped with tilting bar (7) and
lower walkway (8) that can be let down. As soon as the latter is opened, the lift is
automatically locked.
To prevent accidental dropping on people or goods a gridiron guard (9) is installed to stop
machine movement when it touches a foreign body.

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. A special ratchet gear for centrifugal force expands and activates the brake. If
the brake is enabled, a special terminal switch stops movement.
The electric power for the gear motor is supplied via a power supply cable and controls
(15). To prevent the cable interfering with the machinery, special cable clamps (16) must
be attached every 9 m. (In windy areas at least every 6 m). The cable is gathered in a
special container (17) placed on the base.
To make easier the loading and unloading of the deck, two ramps (8) are lowered to form
a support deck. When the ramps are opened and closed, the movement of the lift is
stopped. The lift movement is controlled via a suspended control panel (18) that is
located to the ground or directly connected to the electric board during the assembly and
disassembly stages of the column.
Moreover, the loading deck can be turned by 90
degrees, which allows getting closer the scaffolding or
building. If the deck is not properly closed, a
purposely-designed terminal switch stops any
movement.

Lay underneath the support worm screws some shimming
plates compatible with the total applied load.
The placement area must comply with the following minimum
dimensions, to allow access around the machine for the
various installation and operation jobs.
To assemble the machine use a pair of 24 mm. hexagonal
wrenches..
After the above check, install the machine strictly
following the guidelines below:
x Lay the base on the ground.
x Check that its distance from the wall is regular
matching the type of bolting supplied (minimum
distance 50 cm).
x Use a spirit level to check the horizontal alignment of
the base and the vertical alignment of the column.
Make the necessary adjustments with the 4 lateral
adjusting screws (1). After levelling, lock the screws
with their ring nuts (2).
x Make sure that the screws (4) of the vertical column on
the base (1) are firmly tightened. Otherwise tighten
them properly.
x Check the access ramps (8) and the access closing
arms (9) work regularly.
x Swivel the cable-guide arm (10) to its regular position
and lock it.
x Fit the 2nd column (11) and lock it with the screws
provided.
COPY

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.
x 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.
Before connecting the machine to the
electric power line make sure that:
1. The line is regularly “earthed” and is fitted
with a differential cutout switch (0.3)
2. The power supply matches the machine
voltage.
3. The power supply cable is of the right
width.
4. The earth wire of the machine has been
connected.
x About 1.3 m. above the ground attach the
first cable-guide arm (1) and fix it with a
clamp.
x Place the box (2) of the electric power
supply cable (3) to ensure that it is
regularly unwound and rewound during
up and down movements.
x Plug the machine into the electric power
line by inserting the plug (4).
x Couple the connector (5) of the control
board (8). Test movement by enabling the
control buttons: line, up down, emergency
stop.
x Should the control not coincide with the
motor phases a special device prevents
any movement. The phase inverter (6)
fitted on the door lock mechanism of the
control panel box (7) needs then to be
operated.
x Then enable ascent. A safety device,
proximity switch, stops the vertical
column motor unit from going off course.
The lift is ready for installation of the
following vertical columns.
COPY

14. 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.
The deck can be turned only after the column has been fastened to the wall through
the clamps, as shown in sections 15 and 15a.
x Make sure the installation procedure described above has
been followed.
!!! CAUTION!!! In case of an emergency that requires
the machine to be stopped immediately, press the red
STOP button located on the control board..
x Get onto the deck: by lifting the traverse bars that must
then be closed again and locked using the relevant
locking pegs.
!!! CAUTION!!! The vertical column, for safety purposes,
must always be assembled (and disassembled) on the
deck by TWO AUTHORISED WORKERS wearing a
safety helmet and quick coupling safety belt
x Deck operation is allowed only when the guard (1) is
closed (vertical position).
x Load the 1st vertical column on the deck, lower the guard (1). Fit and connect the 1st
vertical column with the screws provided. Close securely.
x Alight and fit, 2 m. above the ground, the 1st securing bolt (temporary safety bolt for
assembly and disassembly).
xPress the emergency “stop” button to stop any movement.
CAUTION: A photocell control unit built into the motor drive unit automatically
stops the lift near the end of the column.
If stopped, only the deck down movement remains activated.
CAUTION: In case of accidental opening, stops due to collisions etc. all stoppers for
sensor activation automatically cut off the electric power supply. To restore power
subsequently, the green start button mounted on the control board needs to be
pressed.
!!! CAUTION !!! If the nuts and bolts of the vertical column
are not tightened this might cause it to overturn.
1. Refit and clamp the guard (1) to reactivate line authorisation.
2. Load 2 vertical columns and 1 complete securing bolt on the
deck.
3. Release movement by turning the “stop” button. The press
Start.
4. Then assemble the vertical columns and the first securing
bolt that must be fitted 6m. above the ground..
5. Restart descent down to the ground and leave the deck to
conduct the braking tests on the emergency brake (see
page 19).
COPY

19
14a. !!! CAUTION - EMERGENCY BRAKE TESTS !!!
The test must be conducted about every 3 months
and/or whenever the machine is assembled by
personnel trained in compliance with the guidelines
outlined below:
To conduct the test the following conditions must be
met:
xThe machine must be firmly secured.
xThe access area under the loading deck must be
completely cleared and cordoned off to prevent
access.
xThe loading deck must be raised to a height of 3.5 m.
above the ground.
xThe machine must be unloaded.
xThe red emergency button must be pressed on the
pendant control.
To simulate the operation of the emergency brake, the
motor brake must be disabled. By disabling the brake,
the loading deck accelerates down until the emergency
brake is applied.
Therefore, this operation must be performed with
utmost care by previously trained and authorised
workers.
Take the following steps:
xTake the release lever (1) that is screwed on the
motor casing and screw it onto the nearby threaded
hole.
xConnect the lever (1) with a rope made of nylon or
similar material 6-8 mm. in diameter.
xMove about 3 m. from the loading deck and pull the
rope. This action will open the motor brake.
x At this point the machinery always descends faster until it activates the emergency
brake which must be applied 2.5 m. above the ground.. The run, from when the
emergency brakes is applied to when the machinery is definitively locked, must be
around 300 mm.
x Should the machinery not stop, immediately release the rope, to reactivate the motor
brake (that stops the machine).
x In this case, immediately contact the manufacturer or authorised dealer, since the
emergency brake operation is not regular.
x Should the test be positive, load the machine first with 150 Kg. and then with 300 Kg.
and conduct the tests as described above.
x After checking the efficiency of the emergency brake, release the emergency button,
press the start button ( so as to reactive the emergency brake), then lower the machine
to the ground pressing first the up button and immediately afterwards the down button.
x The loading deck will stop at the bottom terminal switch.
x Remove the rope. Unscrew the lever (1) and place it in the casing.
NEVER LEAVE THE RELEASE LEVER COUPLED IN THE BRAKE
Should the braking of both the motor brake and of the emergency brake be either too slow
or too sudden, the brake control must be adjusted by acting as described in the “NON-
ROUTINE MAINTENANCE” section.
COPY

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.
x 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.
x To reactivate ascent, always refit the guard
(1).
x Then proceed likewise for the remaining
modules up to the desired height.
!!! CAUTION!!!
2 m. above the ground the temporary
assembly and disassembly wall bolt must
be attached by clamping it with wall plugs
or other tools as shown in the diagram on
page 22. The wall or the support scaffold
must be able to bear the transmitted loads.
Then attach the wall mounting at least
every 6 m.
x If necessary attach stroke limit stop runners
on the storey (3) so as to ensure it stops at
a preset height.
x Make sure that the storey accesses are
adequately cordoned off and fitted with
warnings on special signs attached to the
inside of the building well stating “free fall
hazard”.
x Every 9 m. (every 6 m in windy areas)
attach cable-guides (4) onto the vertical
column.
After assembling the last vertical column, fit the
up terminal switch runner. Also install the
last wall mounting even if the distance
from the previous one is less than 6m.
x After assembling the vertical column lower
the deck to ground level.
x Remove the control board coupled directly
on the control panel.
x Couple the control board onto the
connector to operate from the ground.
