SPECIFICA
TIONS
cylinders are fully retracted when stowed, protecting
the rod from damage and rust.
TURRET
– Fixture welded steel structure is
constructed from ¾” (19 mm) thick plate wings and a
1.5" (38 mm) thick base plate. The base plate is
machined flat to support the rotation bearing and
gearbox.
LOWER CONTROLS
– Consists of individual control
levers mounted on the turret which actuate the lower
boom, upper boom, rotation, and winch. The lower
controls also include an upper control over-ride/e-stop.
The lower control valve is a full pressure, full flow manual
type valve.
CONTINUOUS ROTATION
- Rotation is continuous
and unrestricted in either direction. The rotation
system consists of a hydraulically driven worm and
spur gear acting on 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. These
critical bolts are torque seal marked to provide a quick
means of detecting any loosening. An eccentric ring
gearbox mounting allows for precise backlash
adjustments.
PINS, BEARINGS, AND LUBRICATION
– Pivot pins
are made from high strength hard chrome plated steel
with fiberglass reinforced Teflon non-lube bearings.
Only the rotation bearing and leveling chains require
lubrication.
34 IN TALL PEDESTAL
- The pedestal is a fabricated
steel structure incorporating a 1.5" (38 mm) thick top
plate which is machined flat to support the rotation
bearing. (The 34 in (0.86 m) height refers to the
installed height, measured from the top of the chassis
frame to the top of the pedestal.)
HYDRAULIC SYSTEM
- The open center hydraulic
system operates at 3000 PSI (210 kg/cm
2
) and
provides up to 8 GPM (30 LPM). With the optional
manual or automatic throttle control, the system
provides up to 8 GPM (30 LPM) at engine idle and 12
GPM (45 LPM) with the throttle advanced.
OIL RESERVOIR
– 30 gallon bulkhead mount
reservoir. Includes cleanout, 10 micron return filter
that can be replaced without draining the reservoir,
filter gauge, 100 mesh (149 micron) suction screen,
gate valve, and magnetic drain plug.
ENGINE START/STOP CONTROL
- An air cylinder
at the upper controls and a toggle switch at the lower
controls operate the system.
HOSES AND FITTINGS
- The high pressure hoses
routed through the booms are non-conductive hoses
with swaged hose end fittings. Retainers are used to
separate the hoses inside the booms to prevent chafing
and nylon sleeves are installed over hoses at points
of movement. Reusable hose fittings can be installed
if a hose is damaged.
ELECTRICAL INSULATION SPECIFICATIONS
- The
upper boom is tested and certified according to ANSI
A92.2 Category C dielectric rating requirements. This
allows the unit to be rated at the design voltage of
46kv and below. Aerial devices may be designed and
configured for gloving work and tool methods at 46KV
and below. The chassis insulating system (lower
boom insert) is also tested and certified according to
ANSI A92.2.
OUTRIGGER/BOOM INTERLOCK
- The outrigger/
boom interlock option is a feature designed to prevent
the lift from being operated until the outriggers contact
the ground. The interlock also prevents the outriggers
from being retracted 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 the rotation bearing relative to the ground.
PAINTING
- The complete unit is primed and painted
prior to assembly. The standard color is white
urethane.
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
This section contains a brief description of some of
the numerous available options.
DUAL UPPER CONTROLS
– Additional 3-axis single
handle controller with safety trigger mounted between
the street side platform and the boom. Available with
dual platforms only.
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.
