INTRODUCTION
PURPOSE OF EQUIPMENT
The SKYJACK SJKB Boom Work Platforms are
designed to transport and raise personnel and tools to
overhead work areas.
USE OF EQUIPMENT
The work platforms (Figure 1-2) are highly maneuverable
work stations. The SJKB-40-D/F and -40-D Models are
designed for both slab-type and rough terrain
construction applications.
Lifting and elevated driving
these models MUST be on a flat, level, compacted
surface.
WARNINGS
The operator MUST read and completely understand
the front panel labels (Figures 1-1) and ALL other warnings
in this manual and on the work platform. Compare the
labels on the work platform with the labels found
throughout Sections 1 and 2 of this manual. If any labels
are damaged or missing, replace them immediately.
DESCRIPTION
The work platform consists of four major assemblies,
the platform, boom assembly, turret and drive chassis.
An operator’s control console is located on the platform.
A foot switch on the platform enables and disables the
platform controls. Auxiliary base controls are located in
the electric panel located on the rotating turret.
PLATFORM - The platform is constructed of a skid-
resistant see-thru deck surface and a 42" high tubular
steel railing system with midrails and 6" toe boards. The
platform can be entered through a sliding midrail bar at
the center of the railing system or optional hinged gate.
The platform can be rotated 90 degrees from center in
either direction. A 110 VAC GFI outlet is also located on
the platform.
BOOM ASSEMBLY - The boom is mounted on the turret
and consists of a 4 foot hydraulic boom jib, telescoping
boom assembly and riser arm. This mechanism uses
double-acting hydraulic cylinders with holding valves to
control vertical movement. Manual lowering valves at
the base of the main boom and jib cylinders allow the
mechanism to lower in the event of an emergency or
electrical system failure.
TURRET - The turret rotates 360 degrees continuously.
On each side of the turret is an enclosure. One with
hinged doors that contains the swing out engine tray,
emergency pump, brake manifold and access to the
turret transportation lock and battery. The other
enclosure contains the fuel tank, the hydraulic fluid tank
and the electrical panel.
DRIVE CHASSIS - The chassis assembly consists of a
rigid one piece weldment and one of the following axle
configurations.
Standard 2WD machines have a straight front axle with
two non-driven wheels, steerable by a double acting
hydraulic cylinder and an hydraulic motor driven rear axle
with spring applied hydraulically released parking brakes.
Optional 4WD machines have a hydraulic motor driven,
rigid drive axle in the rear. The steer axle is coupled to
the rear with a drive shaft. The driven steer axle has an
integrated double acting hydraulic cylinder for steering.
Both axles have spring applied hydraulically released
parking brakes. Machines equipped with the Dual Fuel
Option have LP tank mounting brackets on the side of
the chassis weldment.
PLATFORM CONTROL CONSOLE - Located on the
platform, this control station contains controls for work
platform motion and emergency stopping. Also controls
for engine operation and emergency pump operation.
OPTIONAL ACCESSORIES - The SKYJACK SJKB
Boom Work Platforms are designed to accept a variety
of optional accessories. These are listed in Specifications
and Features found in this section. Operating instructions
for these options (if required) can be found in Section 2
of this manual.
