VERSALIFT VO-270-I

Rear Mounted, insulated 70 ft. 10 in. (21.6 m) overcenter, articulated aerial platform lift, 75ft. 10 n working height (23.1). With 50 ft. 8 in. (15.4 m) over-center horizontal reach.  This vehicle has been designed to meet and exceed the needs of the Massachusetts DCR.  Additionally, we have utilized a Task Relevant Utility Equipment design (TRUE) which takes into consideration the rigors of job, safety demands, job scope and placement of the equipment within traffic patterns.

Aerial Device:
Platform: The fiberglass platform is 24” x 24” x 42” deep with inside and outside step for easy access. The maximum platform capacity is 350 lbs. (161 kg). The VO-270 platform is side mounted and classified as one man.

Tilt Platform:
The tilt platform can be quickly released and tipped for rescue or clean out.

Mechanical Platform Leveling:
Platform leveling is achieved automatically through a completely enclosed parallelogram system. The major components of this system include ½” (13 mm) diameter fiberglass leveling rods, and #60 high strength roller chain. There are no cables used in this system. The fiberglass leveling rods maintain the insulation gaps in all boom positions and are tested at twice the rated load. The tension is adjusted by means of a threaded rod in the upper and lower boom and platform leveling is adjusted by a threaded rod at the turret.

Lower Boom:
The lower boom is designed and constructed from high strength steel plate, forming a 10” x 12” (250mm x 300mm) rectangular tube. Boom articulation is 125º from horizontal to 35º past vertical. Articulation is achieved by using a double-acting hydraulic cylinder equipped with two integral holding valves. In the event of a hydraulic failure, the integral holding valves prevent the booms from dropping by locking the booms in position. In addition, the cylinder rod eye is both threaded and welded.

Chassis Insulating System (Lower Boom Insert):
Each end of a high strength filament-wound epoxy resin fiberglass is inserted into the steel boom sections. A fiberglass insert maintains a 18” (0.61m) insulation between the two steel sections. The steel and fiberglass sections are bonded with pressure-injected adhesive, which fills all the voids. After the adhesive cures, 16 bolts are installed to ensure maximum strength. A stainless-steel stud is supplied at each end of the insert to shunt the chassis insulating system during electrical testing.

Insulated Upper Boom:
The rectangular upper boom tapers from 8” x 12” (200mm x 300mm) at the elbow end to 8” x 10” (200mm x 250mm) at the platform end and is constructed of high strength filament-wound epoxy resin fiberglass. The fiberglass has a gel coat and a high gloss durable urethane finish for added weather protection and water beading. A steel weldment is inserted into the fiberglass at the elbow end of the boom then adhesive is pumped in under pressure to fill all voids. The fiberglass boom is certified for 46KV and below in accordance with ANSI A92.2 Category C dielectric rating requirements. The upper boom articulates a total of 245º relative to the lower boom. A side by side boom design allows low travel height and improved platform access. The upper boom articulation is accomplished by a double acting hydraulic cylinder and 4-bar mechanical linkage. The system does not use any cables and the booms can be stowed in any sequence. A double acting holding valve is provided. An upper boom storage cradle mounted on the turret assures solid boom support in the stowed position. A ratchet-type boom tie-down strap is included.
