GENERAL SPECIFICATIONS
Note: Specifi cations on units may vary or change
without prior notifi cations due to option selections.
This section includes a brief description of each of
the major (standard) components.
PLATFORM - The fi berglass platform is 24 in. x 48
in. x 42 in. (0.61 m x 1.22 m x 1.07 m) deep with an
inside and outside step for easy access.
VST-8000/8500/9000-I -
The
standard
platform
capacity is 800 lbs. (360 kg). With the
optional
jib/winch installed, the platform capacity is 700 lbs.
(318 kg). A cushioned platform support is provided.
VST-9500-I -
The
standard
platform capacity is 600
lbs. (272 kg). With the
optional
jib/winch installed, the
platform capacity is 500 lbs. (227 kg). A cushioned
platform support is provided.
PERSONNEL RESTRAINT SYSTEM - A safety
belt or harness and a lanyard are required and can
be supplied by Time Manufacturing Company at an
additional cost. Consult applicable work practices
and regulations to choose between a safety belt and
a harness. The anchor for the lanyard is attached
to the platform.
INDIVIDUAL LOWER CONTROLS - Individual
full-pressure controls at the turret actuate all boom
functions. The lower control station is equipped with
a selector valve to override the upper controls and
serve as the emergency stop from lower controls.
SINGLE STICK UPPER CONTROL - The full-
pressure single stick upper control includes a
safety trigger to prevent inadvertent operation.
The lift movements correspond with control handle
movements. An emergency stop and a tool selector
control are located at the upper controls.
HYDRAULIC PLATFORM ROTATOR - A hydraulic
platform rotator, operated by a control lever, rotates
the platform 180° from one side of the outer/inner
boom assembly, across the end-hung position, to the
other side of the outer/inner boom assembly.
HYDRAULIC PLATFORM LEVELING - A master
and slave cylinder arrangement automatically levels
the platform in all boom positions. This system also
provides hydraulic platform tilt to adjust platform level,
tilt the platform for clean out, or to ease the removal of
an injured operator. The platform tilt can be activated
from the upper and lower controls.
OUTER/INNER BOOM ASSEMBLY - The outer/inner
boom assembly includes an outer boom, telescopic
inner boom, extension system, and hose assemblies.
The outer boom consists of a 12 in. x 14 in. (305 mm
x 355 mm) steel section. The inner boom consists
of a 9-1/4 x 11-1/4 in. fi berglass section and a 10 x
12 steel section. The fi berglass section provides a
108 in. insulation gap (52 in insulation gap for VST-
9500-I only). The inner boom can be easily removed
and disassembled for service and inspection. The
extension system consists of a hydraulic cylinder, two
integral holding valves, and a “cat-track” type hose
carrier housed entirely within the boom assembly.
The hoses routed through the outer/inner boom
assembly are non-conductive and fully contained
within the boom assembly. The outer/inner boom
assembly articulates from 25° +/-2° below horizontal
to 75° +/-2° above horizontal. Actuated by a double
acting cylinder, equipped with two integral holding
valves; the outer/inner boom assembly is off set to
one side to provide easy access to the platform. A
boom support cradle and a boom tie down strap
are included.
LOWER BOOM WITH CHASSIS INSULATING
SYSTEM
- Each end of a high strength fi berglass
insert (chassis insulating system) is installed over a
rectangular 12 in. x 14-in. (305mm x 355 mm) high
strength steel section. The steel and fi berglass
sections are bonded with pressure injected adhesive
to fi ll any voids. A compensation link with a fi berglass
section maintains the 24-in. (0.61 m) insulation gap
in all the boom positions. The double acting cylinder,
with an integral holding valve, allows the lower boom
to articulate from horizontal to 88° above horizontal.
CYLINDERS - Both the upper and lower cylinders
are a threaded head-cap design. Both cylinders are
equipped with two integral holding valves to prevent
creep down and to lock the booms in position in case
of hose failure.
TURRET - The 5/8 in (16 mm) thick turret wings are
designed for strength and rigidity. The 1-1/2 in (38
mm) thick turret base plate is machined to provide
a fl at surface to support the rotation bearing.
CONTINUOUS ROTATION - Unrestricted rotation
is accomplished by a hydraulically driven worm and
spur gear with a shear-ball rotation bearing. The
critical bolts holding the lift to the rotation bearing
and the rotation bearing to the pedestal are grade 8
hex head capscrews. These critical bolts are torque
seal marked to provide a quick means of detecting
any turning of the bolt upon inspection.
LUBRICATION - Non-lube bearings are used at all
