HYDRAULIC OIL RESERVOIR - A 35 gallon (132 l)
hydraulic oil reservoir is built integral to the pedestal.
The reservoir includes an anti-splash baffle and sight
gauge for quick hydraulic fluid level checks, and a
return filter pressure gauge.
HYDRAULIC SYSTEM - The open-center hydraulic
system operates at 3000 psi (210 kg/cm
2
) at 10 gpm
(38 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. A filter
gauge with a color-coded range is used to monitor
the condition of the return line filter for replacement.
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.
TWO-SPEED MANUAL THROTTLE CONTROL -
Changes the engine/pump speed to give the operator
a choice between slow and normal boom speeds, and
also at slow speed provides reduced flow to operate
hydraulic tools. The manual throttle control is
designed to operate only when the truck engine is
running and the master control is activated. An air
cylinder at the platform or a toggle switch at the turret
can be used to energize the manual throttle control.
PAINT - The complete unit is primed and painted
before 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. 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 designed for open center hydraulic
tools. The tool circuit provides approximately 6 gpm
at engine idle and 10 gpm with the throttle control
engaged. The tool pressure is 2000 psi (140 Bars).
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.
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.
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.
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 rotation bearing relative to the ground.
MANUALS - Two Operator’s Manuals and two Service
Manuals, one Manual of Responsibilities and one EMI
Safety Manual are included with each aerial lift.
VST-7500-I OPTION SPECIFICATIONS
Below is a brief description of some of the available
options for the aerial lift.
4-AXIS CONTROL - The 4-Axis controller option is a
full pressure control located at the platform which
consists of a multi-jointed handle control that actuates
the interlock section and four individual boom function
valves.
TRUGUARD - This advanced upper controls isolation
system provides 4" of electrical isolation from the
entire upper controls, including the control dash
panel. This system also includes a protective shield
which helps prevent environmental and work related
contaminants from making direct contact with the
isolating surfaces.
A-FRAME OUTRIGGERS - A-frame outriggers are
designed and constructed from high-strength steel.
The crossbeam is shipped loose to allow the desired
