Primary assemblies
1.2 Primary assemblies
The MEWP has these primary assemblies:
1. Base
2. Lift mechanism
3. Platform.
1
Base: The base is an assembly consisting of
these components:
▪
A tray, which contains the hydraulic and
electrical components.
▪
A tray, which contains:
▪
For models SJ3215, SJ3219, SJ3220,
SJ3226, SJ4726, and SJ4732: four 6 V
batteries and a charger. The charger for
models SJ3215 and SJ3219 is located at the
rear of the base.
▪
For model SJ4740: four 12 V batteries and a
charger.
▪
The front wheels are steerable by a hydraulic
cylinder.
For models SJ3215, SJ3219, and SJ4740:
the front wheels are driven by two hydraulic
motors.
For models SJ3220, SJ3226, SJ4726, and
SJ4732: the front wheels are non-driven.
▪
The rear wheels have spring-applied,
hydraulically-released brakes.
For models SJ3215, SJ3219, and SJ4740: The
rear wheels are non-driven.

Lift mechanism: The lift mechanism is a scissor-
type assembly made of formed steel or tube
sections. Single-acting hydraulic-lift cylinders
with holding valves move the scissor assembly
and the platform up and down.
