SINGLE AXLE TRAILER FRAME WITH 2" DIAMETER BALL COUPLER AND THIRD WHEEL
A torsion bar type of axle, rated at 3000 pounds, is used for road stability while towing. The 2" diameter ball coupler and
third wheel assembly are provided as standard equipment, allowing the unit to be transported to a job site and unhitched.
WARNING: DO NOT ATTEMPT TO TOW THIS LIFT WITH A HITCH BALL OTHER THAN 2". Safety chains
are also provided and shall always be attached when the unit is to be transported. Tire size is P205/75R14 with a max load
rating of 1532 Lbs. at 35 psi.
PEDESTAL AND UPPER CONTROLS
A full set of controls is provided at both the bucket and the pedestal. ENABLE-OFF-DOWN-OVERRIDE switch is located
at the bucket controls, with an override switch located at the pedestal controls. A key switch is provided at the pedestal
controls for security. A manual boom lowering valve is also provided at the base of the hydraulic pump assembly.
POWER REQUIREMENTS AND CHARGING CAPABILITIES
The unit is powered by two (2) 6 VDC deep cycle batteries, connected in series, yielding 12 VDC for approximately eight
hours of operation under typical use. A built-in 12 VDC, 30 amp battery charger is provided to restore charge to the
batteries, and is equipped with automatic cutoff when full charge is reached. The battery cutout relay permits operation while
the unit is plugged in and the batteries are recharging. (See the section on Inspection and Maintenance for more details on
battery system.)
HYDRAULIC LIFT AND TELESCOPING CYLINDERS
Aerial lift is provided by a 3" single acting cylinder, attached to the upper and lower booms. Telescoping lift is provided
by a 1-1/2" double acting cylinder, located inside the upper boom/telescoping boom assembly. The telescoping boom will
extend up to 9 feet allowing a side reach of approximately 24 feet. Hydraulic power is provided by a 12 VDC hydraulic
system, connected to the 3" lift cylinder attached to the upper and lower booms.
COUNTERWEIGHTS
Four (4) counterweights are mounted at the back of the unit to provide proper stability. These counterweights must always
remain in place when using the aerial lift.
SURGE BRAKES (OPTION)
Hydraulic brakes are available as an option. They are surge activated and use a standard 2" diameter ball coupler. A
breakaway chain is provided for emergency stopping.
LEVELING SAFETY SWITCH (OPTION)
The leveling safety switch continuously monitors the trailer for an unsafe tilt condition (exceeding 5°) during set-up and
operation. The green Trailer Level Indicator Light is on when the trailer tilt is within the 5° range. If the tilt exceeds the
limit during set-up, the controls will not operate. If an unsafe condition occurs during operation, only the "in" and "down"
functions will work.
PERSONNEL BUCKET
The fiberglass personnel bucket is gravity leveled and hydraulically dampened with positive work position locking. The
bucket is made removable for crane operation if required. Travel limits prevent continuous rotation of the boom and bucket.
A body harness is provided with each unit and shall be worn at all times when operating unit from the bucket.
