The CONVENTIONALS
118931AH
Purpose Of Equipment
The SKYJACK SJIII Series Work Platform is designed
to transport and raise personnel, tools and materials
to overhead work areas.
Use Of Equipment
maneuverable, mobile work station. Lifting and driving
MUST be on a flat, level, compacted surface.
Warnings
The operator MUST read and completely understand the
safety panel label located on the platform and ALL other
warnings in this manual and on the work platform.
Compare the labels on the work platform with the labels
found throughout this manual. If any labels are damaged
or missing, replace them immediately.
Description
The work platform consists of three major assemblies,
the platform, lifting mechanism and the base. An
operator’s control box is mounted on the platform
railing. Auxiliary and emergency controls are located
at the base.
Platform
The platform is constructed of a tubular support frame, a
skid-resistant deck surface, and 40 inch to 43-1/2 inch
(1016-1105mm) high railings (depending on model) with
6" toe boards and mid-rails. The platform can be entered
from the rear through an entry chain or optional spring-
returned gate with latch. The platform is also equipped
with an extension platform.
Operator’s Control Box
A removable control box, mounted at the right front of
the platform, contains controls for work platform motion
and emergency stopping.
Lifting Mechanism
- The lifting mechanism is
constructed from steel tubing making up a scissor-type
assembly. The scissor-type assembly is raised and
lowered by single-acting hydraulic lift cylinders. A
pump, driven by a motor, provides hydraulic power to
the lift cylinder. A safety bar located at the front of the
lifting mechanism prevents (when properly positioned)
the scissor-type assembly from being lowered while
maintenance or repairs are being performed within the
lifting mechanism.
Base
The base is a rigid one-piece weldment which
supports two swing-out trays. One tray contains
the hydraulic and electrical components. The other
tray contains the battery charger and eight (8) 6 volt
batteries. The front axle has two non-driven wheels,
steerable by a hydraulic cylinder. The rear axle is a
rigid axle with a self-locking differential and an integral
gearbox. A variable speed 48 V DC electric motor
and holding brake is flange mounted to the gearbox.
Lowering Warning System
(CE only) - Models
are equipped with a lowering warning system as
standard equipment.
Scissor Guards
(CE only) - Models are equipped
with rigid scissor guards mounted on the base as
standard equipment.
Hydraulic Outriggers (if equipped)
- Hydraulic
outriggers are mounted to the four corners of the
base. Controls on the operator’s control box are
used to extend and retract the hydraulic outrigger
cylinders.
Serial Number Nameplate
The serial number nameplate, located at the rear of
the machine, lists the model number, serial number,
machine weight, drive height, capacity and
maximum number of persons, maximum speed,
maximum manual force, maximum incline, platform
height, voltage, system pressure, lift pressure,
ground pressure (tire contact pressure), and date
manufactured. Use this information for proper
operation and maintenance and when ordering
service parts.
