VERSALIFT   VO-452/455/460-MHI

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.

VO-452/455/460-MHI 

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.
