Section 3 - Operation Major Assemblies
3.3 Major Assemblies
The MEWP consists of three major assemblies: base,
lifting mechanism and platform.
3.3-1 Base
The base is a rigid, one-piece weldment which supports
two side compartments.
• One compartment contains the engine, 12V
battery, base control console and electrical
components. The other compartment contains
the emergency lowering system, brake release
and hydraulic components as well as fuel and
hydraulic tanks.
• The propane cylinders (if equipped) are located on
both sides of the hydraulic/fuel compartment.
• The four wheels are hydraulically-motor driven
with two front wheels steerable by a hydraulic
cylinder.
• The rear wheel motors have spring-applied
hydraulically released disc brakes.
3.3-2 Lifting Mechanism
The lifting mechanism is constructed of formed steel or
tube sections making up a scissor-type assembly. The
scissor assembly is raised and lowered by single-acting
hydraulic lift cylinders with holding valves. A two-section
pump, driven by an engine, provides hydraulic power
to the lift cylinders.
3.3-3 Platform
The platform is constructed of a tubular support frame,
a skid-resistant “diamond plate” deck surface and
990 mm hinged guardrails with 152 mm toe boards and
mid-rails. The platform can be entered from the rear
through a spring returned gate with latch. The platform
is also equipped with a manual extension platform. A
220V 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
• Registration 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 chassis inclinations
• Date manufactured
