2. COMPONENT DESCRIPTION
2.1 General description
The basic set of the mast climbing work
platform with rack and pinion drive consists
of the following 5 main parts:
* drive unit
* mast
* platform elements and fences
* chassis or ground frame
* control system
The drive unit moves along the mast with
the aid of Nylontron rollers.
The motors are fitted with centrifugal
brakes which retard the platform if the
speed of descent is exceeded.
The drive unit, operated by 2 electric
motors, is moved along the mast by means
of a single pinion on each motor. For a
mast climbing work platform with two
masts, the motors are automatically
controlled to ensure parallel operation.
Much consideration has been given to
simple and safe assembly and
disassembly.
A crane on the platform (option) ensures
that the mast elements can be positioned
quickly and safely.
The platform can be adjusted to suit the
required working situation with the use of
separate platform elements. The width of
the platform can be adjusted by means of
outriggers.
