PLATFORM
The standard fiberglass platform is 24 in. x 24 in. x 42 in. (.61m x .61m x 1.07m). Hydraulic leveling is standard on the
Tel-EI/EIH/IH/NE models and optional on the Tel-I/N models.
Walk-in and splicing platforms are available.
OUTER/LOWER BOOM ASSEMBLY
The major components of the outer/inner boom assembly
includes an outer boom, a telescoping inner boom, an extension
cylinder, a hose carrier system, and slide pads mounted on the
inner and outer boom. The outer boom consists of a 6in. x 8in.
(.15m x .20m) rectangular steel section and a 9 1/2 x 7 1/2 in.
(.24m x .19m) fiberglass section (Electrogard) that maintains a
42 in. (1.07m) insulation gap. The telescoping inner boom is a
5in. x 7in. (.13m x .18m) 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 and 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
assembly with adequate space to carry hoses and wiring to the
upper control station. A boom support cradle and a boom tiedown
strap are included.
CONTROL VALVES
The system pressure relief, hydraulic leveling (if applicable), and
the hydraulic boom function valves are a single integrated system
mounted on the turret wing.
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 the boom from
creeping 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.
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 to the rotation bearing and the rotation
bearing to the pedestal meet SAE grade 8 specifications. 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.
HYDRAULIC SYSTEM
The hydraulic system can be powered by the chassis-engine, a
chassis-transmission power take-off or more advanced options.
LUBRICATION
Non-lube bearings are used at all pivot points. The rotation bearing
is the only component that requires lubrication.
