OUTER/INNER BOOM ASSEMBLY
The major components of the outer/inner boom assembly includean 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.
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.
Non-lube bearings are used at all pivot points. The rotation bearing is the only component that requires periodic lubrication.
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 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.
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.
