SPECIFICA
TIONS
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 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. Toggle switches at the
upper controls and the pedestal are used to 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/cm2).
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.
OPTION SPECIFICATIONS – VST-39/43/
50/55-TN
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-39/43 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
be used in conjunction with the rear torsion bar to
reduce the amount of ballast needed.
BACKUP PUMP - An auxiliary hydraulic pump
designed to bring the booms down in case the main
hydraulic source fails. The backup pump is driven by
a DC motor, which is powered by the truck-engine
battery. The system is connected in parallel with the
main pump and is designed for non-continuous
operation. Toggle switches at the upper controls and
the pedestal are used to energize the system.
120V WIRING – Consists of a 12ga 3-conductor wire
between the platform and pedestal, with a GFCI outlet
at the platform. This option requires 3 additional slip
rings.
SECOND SET OF TOOL POWER PORTS - A second
set of tool power ports are installed at the platform to
accommodate a second open center tool.
EXTRA CONTROL CIRCUIT - Consists of an
additional toggle switch at the platform and at the
pedestal and 14 ga. wire to the platform. An additional
pass in the collector ring is required for each control
circuit.
MANUAL THROTTLE CONTROL - Gives the operator
a choice of economical engine idle speeds or faster
engine speeds with faster lift movements when
required. The manual throttle control is designed to
operate only when the truck engine is running and
the master control is activated. Toggle switches at
the platform or at the pedestal can be used to energize
the manual throttle control.
