GENERAL SPECIFICATIONS – VST-36/
40/47/52-I
Note: Specifications on units may vary or change
without prior notifications due to option selections.
This section includes a brief description of each of
the major (standard) components.
PLATFORM
- The closed fiberglass platform is 24
In. x 24 In. x 42 In. deep (.61 m x .61 m x 1.07 m)
with an inside and outside step for easy access.
Maximum rated platform capacity
for all models is
600 lbs (272 kg) without jib/winch and 500 lbs (227
kg) with jib/winch.
The actual platform capacity may be reduced
depending on the chassis and mounting configuration.
See “Vehicle Specifications” for the actual platform
capacity of a particular installation.
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 support.
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.
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 ROTATION
- A hydraulic
rotary actuator, operated by a control lever, rotates
the platform 180° from one side of the boom, to the
end-hung position, and to the other side of the boom.
HYDRAULIC PLATFORM LEVELING
- A master
and slave cylinder controls platform leveling. The
leveling system can be operated from the upper or
lower controls to adjust platform leveling, tilt the
platform for clean out, or to ease the removal of an
injured operator.
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 an 8 in. x 10 in. (203 mm
x 254 mm) steel section, with a 9 in. x 11 in. (229
mm x 279 mm) fiberglass Electroguard section (N/A
on VST-52). The 6-7/8 in. x 8-7/8 in. (165 mm x 216
mm) rectangular fiberglass inner boom is housed
within the outer boom. The extension system
consists of an extension cylinder, holding valves, and
a hose carrier housed inside the boom. The hoses
routed through the outer/inner boom assembly are
non-conductive and fully contained within the boom
assembly.
A double acting cylinder with two integral holding
valves articulates the outer/inner boom assembly. A
boom support cradle and a boom tie down strap are
included.
LOWER BOOM WITH CHASSIS INSULATING
SYSTEM
- Each end of a high strength fiberglass
insert (chassis insulating system) is installed inside
a rectangular 8 in. x 10 in. (203 mm x 254 mm) high
strength steel section. The steel and fiberglass
sections are bonded with pressure-injected epoxy
to fill any voids. A double acting cylinder, with two
integral holding valves, articulates the lower boom.
The lower boom and compensation link form a
parallelogram linkage to maintain the knuckle at a
constant angle to the turret.
CYLINDERS
- Both the upper and lower cylinders
are a threaded head-cap design. Both are equipped
with two integral holding valves that prevent down
creep and to lock the booms in position in the event
of hose failure.
TURRET
- The turret wings are designed for strength
and rigidity. A bearing cover seals out moisture and
prevents foreign materials from obstructing the turret
rotation. The turret plate is machined to provide a
flat 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. An eccentric
ring is used for gearbox backlash adjustment.
LUBRICATION
- Non-lube bearings are used at most
points of motion. Only the rotation bearing requires
periodic lubrication.
PEDESTAL
- The pedestal is tubular with a reinforced
