Section 3 - Operation

Major Assemblies

3.3 Major Assemblies

The MEWP consists of four major assemblies: the base,
turret, boom assembly and platform.

3.3-1 Base

The base is a rigid one-piece weldment. The rear axle
is hydraulic motor-driven and has a spring-applied,
hydraulically released brakes. The front axle is steerable
by a hydraulic cylinder and has spring-applied,
hydraulically released brakes. The rear axle is coupled
to the front axle by a drive shaft.

3.3-2 Turret

The turret rotates 360 degrees continuously. Upon
the turret are two compartments. One compartment
contains the engine, hydraulic pumps, battery and swing
drive. The other compartment contains the base control
console, main hydraulic manifold, function valves, the
hydraulic and fuel tanks.

3.3-3 Boom Assembly

The boom is mounted on the turret and consists of a
telescoping fly, mid boom and main boom assembly.
The telescoping boom mechanism uses two double-
acting hydraulic cylinders with holding valves to control
vertical movement. Cables are used to extend the fly
boom section. The SJ86T model is equipped with a

150 cm (60 in.) boom jib, controlled by a double-acting
hydraulic cylinder.

3.3-4 Platform

The platform is constructed of a skid-resistant deck
surface allowing visibility through the deck and a 109 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 swing side gate or an optional swing
gate at the center of the railing system. The platform can
be rotated in either direction. An AC GFI outlet is also
located on the platform.

3.4 Serial Number Nameplate

The serial number nameplate, located at the rear of the
MEWP, lists the following:

•

Model number

• Serial number
•

Maximum capacities

•

Maximum number of persons permissible on the
platform

•

Maximum manual force

•

MEWP weight

•

Maximum drivable height

•

Maximum platform height

•

System pressure

•

Lift pressure

•

Maximum wheel load

•

Maximum wind speed

•

Voltage

•

Maximum inclination of chassis
