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

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.
