VST-7500-I GENERAL SPECIFICATIONS
Note: Specifications on units may vary or change
without prior notification due to option selections.
This section includes a brief description of each of
the major (standard) components.
PLATFORM - The fiberglass 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. 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.
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. fiberglass section and a 10 x 12
steel section. The fiberglass section provides a 108
in. insulation gap. 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 offset 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 fiberglass
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 fiberglass
sections are bonded with pressure injected adhesive
to fill any voids. A compensation link with a fiberglass
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
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.
LUBRICATION - Non-lube bearings are used at all
pivot points. Only the rotation bearing and rotation
bearing gear teeth require periodic lubrication.
PEDESTAL - The pedestal is rectangular with a
reinforced mounting plate. The top plate of the
pedestal is 1-1/2 in. (38 mm) thick and machined flat
to support the rotation bearing.
