Purpose Of Equipment
The SKYJACK SJ-600, 800 & 1000 Series Work
Platform is designed to transport and raise personnel,
tools and materials to overhead work areas.
Use Of Equipment
The work platform
(Figure 1-1)
is a highly
maneuverable, mobile work station. Lifting and
elevated driving MUST be on a flat, level, compacted
surface. The work platform can be driven over uneven
terrain only when the platform is fully lowered.
Warnings
The operator MUST read and completely understand
the safety panel labels 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 “diamond plate” deck
surface, and 43-1/2" (1.10m) hinged railings with 6"
(15.24cm) toe boards and mid-rails. The platform can
be entered from either side through a spring returned
gate for 800 & 1000 Series and from the rear through
a spring returned gate on 600 Series. The 600 Series
can be equipped with a front extension platform. The
800 & 1000 Series can be equipped with a front or both
front and rear extension platforms.
Lifting Mechanism
- The lifting mechanism is
constructed of formed steel sections making up a
scissor-type assembly. The scissor-type 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. A safety bar located inside the lifting
mechanism (when properly positioned) prevents the
scissor-type assembly from being lowered while
maintenance or repairs are being performed within
the lifting mechanism.

INTRODUCTION
Base - (600 & 800 Series)
The base is a rigid
one piece weldment which supports two component
side cabinets. One cabinet contains the hydraulic
components, up/down controls, electrical compo-
nents and starter battery. The other cabinet contains
the fuel tank, hydraulic tank and LP tank (SJ 800).
The propane tank on the SJ 600 series is located
either behind the access ladder or behind the fuel
cabinet. The front axle has two wheels, steerable by
a hydraulic cylinder and is either non-driven (2WD
models) or drive shaft/gear box driven (4WD models).
The rear axle is drive shaft/gear box driven and has a
spring-applied hydraulically-released disc parking
brake. A slide-out drawer at the front of the base,
supports an engine coupled with a two-section
hydraulic pump providing power to the hydraulic
system. An engine control panel is also located at the
front of the base.
Base -
(1000 Series)
The base is a rigid one
piece weldment which supports two component side
cabinets. One cabinet contains the hydraulic tank,
hydraulic components, up/down controls, electrical
components, emergency lowering battery and starter
battery. The other cabinet contains the fuel tank and
LP tank (if equipped). The front axle has two wheels,
steerable by a hydraulic cylinder and is either non-
driven (2WD models) or drive shaft/gear box driven
(4WD models). The rear axle is drive shaft/gear box
driven and has two spring-applied hydraulically-
released parking brakes. A slide-out drawer at the
front of the base supports an engine coupled with a
two-section hydraulic pump providing power to the
hydraulic system. An engine control panel is also
located at the front of the base.
Operator’s Control Box
-
A removable control
box, mounted at the right front of the platform,
contains controls for engine operation, work platform
motion and emergency stopping.
Hydraulic Outriggers
-
Optional 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.
