mounting plate. The top plate of the pedestal is 1-1/
4 in. (32 mm) thick and machined flat to support the
rotation bearing.
HYDRAULIC OIL RESERVOIR - A 17 gallon (64.4
l) hydraulic oil reservoir is built integral to the
pedestal. Two sight gauges allow quick hydraulic
fluid level checks.
HYDRAULIC SYSTEM - The open-center hydraulic
system operates at 3000 psi (210 kg/cm
2
) at 6 gpm
(22.7 lpm). A 10-micron return-line filter, mounted
above the hydraulic oil level and inside the pedestal,
can be easily changed without draining the reservoir.
The 100 mesh (149 micron) suction strainer in the
reservoir can be removed for cleaning. A gate valve,
located below the reservoir, prevents oil loss when
the pump is serviced. A magnetic drain plug attracts
metal particles from the oil.
PAINT - The complete unit is primed and painted
prior to assembly. The standard color is white
urethane.
HOSES AND FITTINGS - The hoses routed through
the booms are high pressure and non-conductive
with swaged hose end fittings. Retainers separate
the hoses inside the booms to prevent chafing and
nylon sleeves are installed over hoses at points of
movement. Reusable fittings can be installed if a
hose is damaged.
ENGINE START / STOP - The start/stop circuit has
been designed so the lift cannot be operated unless
the truck ignition switch is in the “RUN” position and
the master control is activated. This feature makes
it difficult for unauthorized individuals to operate the
lift when the truck is locked. An air cylinder at the
upper controls and a toggle switch at the pedestal
energize this system.
HYDRAULIC TOOL CIRCUIT AT THE PLATFORM
- This system is intended for open center hydraulic
tools. The tool circuit provides 6 gpm (22.7 lpm). A
pressure reducing valve in the tool circuit limits the
tool pressure. The valve can be adjusted from 1000
to 2500 psi (70 to 175 kg/cm
2
).
LINE-LIFTING SOCKET - Built as part of the
platform support structure, is a vertical line-lifting
socket for 3 in. (76 mm) diameter line-lifting
attachments. The socket is automatically leveled
with the platform without any manual adjustments.
ELECTRICAL INSULATION SPECIFICATIONS -
The outer/inner boom assembly is tested and
certified for electrical work at 46 KV and below in
accordance with ANSI A92.2 requirements. Aerial
devices may be designed and configured for gloving
work and tool methods at 46KV and below. The
outer/inner boom assembly is fully insulated even in
a retracted position. The chassis insulating system
(lower boom insert) is also tested according to ANSI
A92.2.
SLOPE INDICATORS - Slope indicators are required
on Versalift units and supplied by Time Manufacturing
Co. Slope indicators shall be installed to indicate
the level of the rotation bearing relative to the ground.
OUTRIGGER / BOOM INTERLOCK SYSTEM - The
outrigger/boom interlock system prevents lift operation
until the outriggers contact the ground and outrigger
retraction before the aerial lift is properly stored.
MANUALS - Two Operator’s Manuals, two Service
Manuals, one Manual of Responsibilities, and one
EMI Safety Manual are included with each aerial lift.
OPTION SPECIFICATIONS – VST-36/40/
47/52-I
Below is a brief description of some of the available
options for the aerial lift.
OUTRIGGERS - The modified A-frame outriggers are
equipped with pilot operated check valves, internal
thermal relief valves, pivot feet, and separate controls.
Outrigger dimensions vary with chassis application.
For a 31 in. (0.79 m) frame height, the, the outriggers
furnish 122 in. (3.1 m) of spread, 8 in. (203 mm) of
penetration, and 18 in. (457 mm) of ground clearance.
For a 37-1/4 in. (0.95 m) frame height, the, the
outriggers furnish 125-3/8 in. (3.2 m) of spread, 8 in.
(203 mm) of penetration, and 18 in. (457 mm) of ground
clearance.
INDEPENDENT OUTRIGGERS – Narrow angle
modified A-frame outriggers are shear-plate
mounted to the frame and are equipped with pilot
operated check valves, internal thermal relief valves,
pivot feet, and separate controls. Outrigger
dimensions vary with chassis application. For a 37-
1/4 in. (0.95 m) frame height, the outriggers furnish
101-3/4 in. (2.6 m) of spread, 7-3/4 in. (197 mm) of
penetration, and 15-3/4 in. (400 mm) of ground
clearance.
TORSION BAR – (VST-36/40 only) An over-frame or
under-frame torsion bar for the rear axle adds stability
to the vehicle and is available as an option. Ballast
may be required with the use of a torsion bar. A front
axle under-frame torsion bar is also available and can
