CONSTRUCTION
SADDLE ASSEMBY
Manufactured from 5mm steel plate the saddle assembly has an integral hydraulic oil
reservoir, access to which is via a removable cover. The saddle assembly is mounted
directly onto the sub chassis.
STABILISERS
The platform is equipped with four hydraulically powered stabilisers. They are enclosed
in removable box section legs that are part of the saddle/subframe assembly and when
stowed are within the vehicle width.
Each stabiliser may be independently operated from the control valve, each leg has
sufficient travel to level the platform on uneven ground.
BOOM STRUCTURE
The structure consists of two articulating booms and one telescopic boom fabricated
from structural steel. The platform has a wide operating range with movement limited by
ram stroke. The full payload can be supported in all positions of the booms.
HYDRAULIC CYLINDERS
Double acting hydraulic cylinders control the raising and lowering of the boom structure.
The cylinders are manufactured from honed tube and are fitted with hard chromium
plated piston rods.
SLEWING MECHANISM
360º non-continuous slewing is provided by means of a worm drive slew ring. This
combination is self-locking when stationary and gives precise control during operation. A
manual rotation facility is provided for use in the event of either a loss of hydraulic power
or engine failure.
CAGE LEVELLING
A master / slave hydraulic cylinder arrangement ensures positive leveling of the
personnel cage in all positions.
PERSONNEL CAGE
For two-man operation a precision moulded polyethylene cage is supplied as standard, a
moulded handrail is incorporated along the top edge of the cage. Two safety harness
anchor points are provided inside, which conform to EN795. The cage is electrically
insulated to 1kv. The work platform is not intended for live line working.
