OUTER/INNER BOOM ASSEMBLY
The major components of the outer/inner boom assembly include
an outer boom, a telescoping inner boom, an extension cylinder,
a hose carrier system, and slide pads mounted on the inner and
outer booms. The outer boom consists of a 6 in x 8 in. (152 mm x
203 mm) rectangular steel section. The telescoping inner boom
consists of a 5 in. x 7 in. (128 mm x 178 mm) rectangular aluminum
(non-insulated) or fiberglass (insulated) housed within the outer
boom. The inner boom does not have to be removed to service
the extension cylinder or slide pads. The extension system
consists of a hydraulic cylinder with wear rings on the piston and
end gland and a holding valve mounted to the cylinder base. The
hose carrier system is a multi-link metal assembly with adequate
space to carry hoses and wiring to the upper control station. The
telescoping outer/inner boom assembly articulates from 80 below
horizontal to 800 above horizontal. A double acting cylinder, equipped
with a counter balance holding valve, provides boom elevation. A
boom support cradle and boom tie-down strap are included.
CYLINDERS
The extension cylinder has wear rings on the piston and end
gland for extended seal life. A double acting holding valve is
mounted at the extension cylinder base to prevent boom creep
during travel or uncontrolled movement in case of hydraulic hose
failure. The extension cylinder can be removed without removing
the inner boom. The boom elevation cylinder has a single acting
holding valve.
LUBRICATION
Non-lube bearings are used at all pivot points. The rotation
bearing is the only component that requires periodic lubrication.
UPPER CONTROL
The VANTEL-29-IH/EIH platform has a manually operated
hydraulic valve mounted to the platform, which controls the boom
and platform movements. The control handles are locked in the
center (neutral) position. If the unit is in operation and the operator
releases any functioning control handle, it will return to the off and
locked position. On the VANTEL-N (side-mounted platform), all
switches are recessed into the inner boom. The VANTEL-NE
(end-mounted platform) has the control panel mounted inside
the platform. To protect against inadvertent operation, a spring
loaded master control switch is provided.
ROTATION
Rotation is 3600 (with an electric limit switch) to 3700 (with a
mechanical limit switch) non-continuous to prevent hose and
wiring damage. Continuous unrestricted rotation is available as
an option. Rotation is accomplished by a hydraulically driven worm
and spur gear and a shear-ball rotation bearing. The critical bolts
holding the lift or turret to the rotation bearing and the rotation
bearing to the pedestal are SAE grade 8. These critical bolts are
torque seal marked to provide a quick means to inspect for
loosening. An adjustment screw is provided to adjust pinion and
rotation gear clearances.
PLATFORM
The standard fiberglass platform is 24 in. x 24 in. x 42 in. (.61 m x
.61 m x 1.07m). Hydraulic leveling is standard on the VANTELEIH,
VANTEL-IH and VANTEL-NE (end-mounted platform).
Hydraulic leveling is optional on the VANTEL-N (side-mounted
platform). Walk-in, splicing and rotating splicing platforms are
also available.
