This section includes a brief description of each of
the major (standard) components.
PLATFORM - The fi berglass platform is 24 in. x 24
in. x 42 in. (0.61 m x 0.61 m x 1.07 m) deep with
an inside and outside step for easy access. The
platform capacity is 300 lbs. (136 kg).
SINGLE STICK PLATFORM CONTROL - The
Unitrol single-stick control consists of a multi-jointed
handle which operates the control valve. A safety
trigger located on the underside of the single stick
handle will not allow boom movement until it is
depressed. The control valve is full pressure and full
fl ow. The operator can feather between the three
control movements to provide multi-function boom
action. An emergency stop control is provided.
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.
HYDRAULIC PLATFORM LEVELING - Platform
leveling is controlled by a master and slave cylinder
arrangement. The platform leveling system can be
activated from the upper controls to adjust platform
leveling, tilt the platform for cleaning, or to ease the
removal of an injured operator.
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 upper platform support.
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 6 in. x 8 in. (150 mm
x 200 mm) steel section and a 7.5 in. x 9.5 in. (190
mm x 240 mm) fi berglass section (Electroguard)
that maintains a 42 in. (1.08 m) insulation gap with
the inner boom fully retracted. The 5 in. x 7 in. (130
mm x 180 mm) rectangular fi berglass inner boom
is housed within the outer boom. The extension
system consists of a hydraulic cylinder, two holding
valves, and a 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 14°
below horizontal to 74° above horizontal. Actuated
by a double acting cylinder with a holding valve,
the outer/inner boom assembly is off set to one side
to provide easy access to the platform. A molded
rubber boom-support cradle supports the boom
when stowed, without the need for a tie-down strap.
COMPENSATED LOWER BOOM - The lower boom
consists of a 6 in. (150 mm) square steel section.
A double acting cylinder with dual holding valves
allows the SST-37 lower boom to articulate from
7° below horizontal to vertical for a total travel of
97°. The SST-40 lower boom articulates from 5°
below horizontal to vertical for a total travel of 95°.
A compensation link forms a parallelogram linkage
to maintain the outer/inner boom assembly at a
constant angle to the turret.
PINS - Pins are high-strength alloy steel which
are chrome plated for a hard fi nish and corrosion
resistance. Pins are bolted in place with a welded
pin tab at one end and a pin cap at the other for
redundant retention.
CYLINDERS - Both the outer and lower boom
cylinders are a threaded end-cap design. The
lower boom and extension cylinders are equipped
with two holding valves to prevent down creep and
to lock the booms in position in the event of hose
failure. The outer boom cylinder is equipped with
one holding valve.
TURRET - The turret wings are 1/2 in. (13 mm)
thick steel plate. A steel tube is welded between
the turret wings to support the boom cylinder and
provide rigidity. The turret plate is machined fl at
to support the rotation bearing. A bearing cover is
provided to prevent foreign material from interfering
with lift rotation.
ROTATION - Rotation is 370°, non-continuous with a
mechanical stop. Continuous, unrestricted rotation
is available as an option (see option descriptions).
Rotation is accomplished by a hydraulically driven
worm and spur gear set acting on a shear-ball
rotation bearing. The critical bolts holding the
turret to the rotation bearing and the bearing to the
pedestal are grade 8 hex head cap screws. These
critical bolts are marked with a torque seal indicator
to provide a quick means to inspect for relative
movement. A slotted adjustment is provided for
pinion and rotation gear clearances. An external
hex drive is provided for manual rotation in case of
hydraulic failure.
