Major Assemblies
The MEWP consists of four major assemblies: the
base, turret, boom assembly and platform. Refer to
Figure
02.
1.2-1 Base
The base is a rigid, one-piece weldment, which
supports two swing out battery trays. The rear axle
is electrically motor-driven and has spring-applied,
electrically released brakes. The front axle is steerable
by a hydraulic cylinder.
1.2-2 Turret
The turret rotates 352 degrees. The turret supports
two compartments. One compartment contains
the pump/motor unit, hydraulic filter, hydraulic tank
and emergency pump unit. The other compartment
contains the base control console, main manifold,
and function valves. The swing drive is located
underneath the turret.
1.2-3 Boom assembly
The boom assembly consists of the riser, telescoping
fly and main boom assembly. The riser is mounted
on the turret with the main boom, attached to the
riser. The riser mechanism uses two double-acting
hydraulic cylinders with holding valves to control
vertical movement. AJE & ARJE models are equipped
with a 124 cm (49 in) jib, controlled by a double-
acting hydraulic cylinder.
1.2-4 Platform
The platform is constructed of a skid-resistant deck
surface allowing visibility through the deck and a
110 cm (43 in) high tubular steel railing system with
mid rails and 15 cm (6 in) toe boards. The platform
can be entered through a drop bar, located opposite
the control box side. The platform can be rotated in
either direction. An AC outlet is also located on the
platform.
