What Is Insulated and What Is Not Insulated
Articulated/Telescopic and Articulated Models
Area 1, Boom Tip Area – The boom tip area does
notprovide insulation. Thisareaincludeseverything
pasttheinsulated section decal*onthe upperboom.
This includes the upper end of the boom, platform
support,platform(s),controls, andthejib/winch/rope
(when so equipped).
All components at the boom tip area must be
considered to be conductive and electrically
connected,even withaninsulated linerinplace.Any
contact with a ground and a phase or between two
phase conductors will create a hazard of serious
personal injury or death. Contact between an
energized conductor and any part of the boom tip
will energize the entire boom tip.
Whenworking nearan energized conductor, ground
conductor, or other grounded objects, the operator
must use the proper safety equipment (such as
rubbergloves, covers,hotsticks,etc.), maintain safe
approach distances, and follow company work
practices.
Area 2, Upper Boom Insulation Section – This
section provides insulation** between the boom tip
area and earth ground when clean and properly
maintained. Onsomeconfigurations, itisnecessary
to extend the boom until the insulated section decal
is visible.
Area 3, Intermediate Structure –This sectiondoes
not provide insulation. This area includes the lower
steel portion of the upper boom, knuckle, and the
steel upper portion of the lower boom and
compensation link (when applicable).
Area 4, Lower Boom Insulating Section – (When
so equipped) This section provides insulation**
between the intermediate structure (Area 3) and the

ADDITIONAL SAFETY CONSIDERATIONS
1. Report any unusual occurrence during the
operationoftheaerialliftthatmayrequirerepair
oradjustment.
2. Keep the work space in the truck bed clean
andneat.
3. Avoid parking on soft surfaces. Soft surfaces
may suddenly collapse, shift, or sink beneath
the truck’s weight.
4. There is no insulating value in the fiberglass
platformwithouta platformliner.
5. No attempt should be made to clean, oil, or
adjust a machine while the machine is in
motion.
6. Ifanaeriallifthassetidleforanextendedperiod
(i.e. overnight) or has been recently serviced,
cycle the aerial-lift through it’s full range of
motionseveraltimes. Thisprocedurewillforce
any trapped air out of the hydraulic system.
Do not operate the lift from the platform until
this process is completed. Air trapped in the
hydraulic oil can cause lift movements to be
erraticandunpredictable.
7. Don’t operate any part of the unit (platform,
booms, outriggers, etc.) outside the work-site
barricades into the traffic lanes. Set up
adequate cones or barricades to mark the
boundaries of the work-site to alert motorists
andpedestrians.
8. Only qualified mechanics are authorized to
servicethe aeriallift.
9. The polyester winch rope is not an insulator.
Dirt,grease,and moisture(humidity)makethe

10. Make a thorough check of the winch rope for
abrasive wear, pulled strands, cuts, and other
defects daily.
11. Replace the winch rope at the first sign of
damage or deterioration. Use only non-
conductiverope ofthesizeand typespecified.
12. Avoid shock loads. Ashock load is caused by
jerkingaline withaloador asuddenchangein
rope tension from a light load to a heavy load.
13. Do not contact energized conductors with the
winch line. Contacting the load line with an
energized conductor could create a complete
path for electricity when the rope is extended
to the ground. This could cause death or
seriousinjury.

SPECIFICATIONS
SPECIFICATIONS
VST-7500-I GENERAL SPECIFICATIONS
Note: Specifications on units may vary or change
withoutprior notificationdue tooption 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.

3-2 29084-05 03/17VERSALIFT VST-7500-I
SPECIFICATIONS
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/cm2) 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.
