Boom Design: A tubular steel lower boom is connected to the upper boom with the use of a mid-pivot joint Mechanical linkage provides platform leveling that is maintenance free. Lift cylinders include integral holding valves, along with manual lowering valves for independent lowering of each assembly.

Terrain Capability : All electric drive "A" series booms come standard with 600x9 solid rubber tires. These machines with their 5" ground clearance will work on all "slab type" job-sites. Optional flotation air tires will allow these machines to be used for "off-slab type" jobs as well.

Chassis: Chassis is designed the same for both machines so all components will interchange from one to another. All options can be installed without any chassis modification on both models.

Drive System: Both machines are two wheel fully proportional direct electric drive with power supplied by an electric motor on each drive wheel, with a high speed of 3.2 mph. Both drive wheels are also supplied with an electrically released spring applied brake. These brakes are automatically applied anytime the drive controller is returned to the neutral position.

Weight: A28 has a gross weight of 5,560 lbs. A32J has a gross weight of 7,150 lbs (with a 4' Jib). Both machines are designed to be self-loading onto most trailers.

Ground Controls: Secondary control system with a NEMA drip-proof enclosure, conveniently located on the right side of the tower at eye level allows the operator to see the lower controls at all times. The three dimensional decal easily identifies switches for all functions. All of the "A" series booms use a Sevcon MOS 90 controller with the latest state-of-the-art Mosfet and microprocessor technologies. These controllers are highly efficient for small to medium sized electric vehicles such as personnel lifts. The powerful microprocessor used in the MOS 90 range offers advanced features previously unavailable in such a compact controller.
