VO40 MHI – Ford F550 4×4
Description
AERIAL LIFT SPECIFICATIONS
PLATFORM – The fiberglass platform is 24” x 30” x 42” deep (0.61m x 0.76m x 1.07m) with inside and outside step for easy access. The platform capacity is 400lbs. (180kg). A hydraulic cylinder rotates the platform through 90o travel. Rotation control is located at the platform. Platform will be stowed in the high position.
PLATFORM LINER AND VINYL COVER – A 50 kV rated liner and soft vinyl cover are supplied for the platform.
MECHANICAL PLATFORM LEVELING – Platform leveling is achieved automatically through a completely enclosed parallelogram system. The major components of this system include 1” (25 mm) diameter fiberglass leveling rods, and #100 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 another threaded rod at the turret.
MANUAL PLATFORM TILT – This allows the platform to be tilted for clean out or rescue. A cam lock releases the platform and hydraulic dampeners limit the speed of the platform tilt.
LOWER BOOM – The lower boom is designed and constructed from high strength steel plate, forming a 12” x 12” (300mm x 300mm) square tube. Boom articulation is 110o from horizontal to 20o 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 12” insulation gap 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 8” x 10” (200 mm x 250 mm) rectangular upper boom 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. After the adhesive cures, 8 bolts are installed to assure maximum strength. 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 240o relative to the lower boom, from –10o to 230o. 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 assures solid boom support in the stowed position. A ratchet-type boom tie-down strap is
included.
TURRET – The turret wings are designed for strength and rigidity. The bearing cover is continuously welded to seal out moisture and prevent foreign materials from obstructing the turret rotation. The 1 1⁄4” (32mm) turret base plate is machined to provide a flat surface to support the rotation bearing.
PAINT – The complete unit is primed and painted before assembly. The standard color is white urethane.
CONTINUOUS ROTATION – Rotation is continuous and unrestricted in either direction. This is accomplished by a hydraulically driven worm and spur gear with a shear-ball rotation bearing. The critical bolts holding the lift to the rotation bearing and the rotation bearing to the pedestal are grade 8 hex head cap-screws. These critical bolts are torque seal marked to provide a quick means of detecting any turning of the bolt upon inspection. An eccentric ring gearbox mounting allows for precise backlash adjustments.
LUBRICATION – Non-lube bearings are used at most points of motion. Only the rotation bearing, and extension chain require lubrication.
PEDESTAL – The pedestal is a fabricated steel structure incorporating a 1 1⁄4” (32 mm) top plate which is machined flat to support the rotation bearing.
HYDRAULIC SYSTEM – The open-center hydraulic system operates at 2500psi (175 kg/cm) at 6 gpm (23 lpm). A 10- micron return-line filter, mounted above the hydraulic oil level and inside the pedestal, can easily be changed without draining the reservoir. A filter gauge with a color coded range is used to monitor the condition of the return line filter for replacement. The 100 mesh (149 micron) suction strainer in the reservoir can be removed for cleaning. A gate valve, located below the reservoir, prevents oil loss when the pump is serviced. A magnetic drain plug is included.
JIB AND WINCH – A material handling jib and winch with an 1100 lbs. (500 kg) capacity. The jib pole is 4” square and hydraulically articulates 120°, from –30° to +90°. A self-locking worm gearbox hydraulically powers the winch, so a brake is not required. The winch includes 70ft of 7/16 in diameter winch line with a braided hoop and clevis hook. A control valve for the winch is provided at both the upper and lower controls.
HYDRAULIC JIB POLE EXTENSION – An 18” stroke hydraulic cylinder pins in 3 positions to extend and retract the jib pole under full rated load. The cylinder can be re-pinned under load to travel through the entire 1.5 to 5 ft extension range.
HYDRAULIC OIL RESERVOIR – The hydraulic oil reservoir is an integral part of the pedestal. The capacity of the reservoir is 17 gallons (64 L). The reservoir is baffled and includes a 100 mesh suction strainer, 10 micron return filter, and sight level gauge.
CYLINDERS – Both the upper and the lower cylinders are a threaded head-cap design. The upper cylinder is equipped with two integral holding valves to prevent creep down and lock the booms in position in case of hose failure. All holding valves are recessed into the base of the cylinders to provide protection from falling objects. When stowed, both cylinder rods are retracted, protecting them from damage and rust.
HYDRAULIC TOOLS – One set of hydraulic tool ports (one pressure port and one return port) are standard at the upper controls. The tool circuit provides a 6 gpm (23 lpm) at 2500psi.
HYDRAULIC TOOL CIRCUIT AT THE GROUND – This system is intended for open center hydraulic tools. The tool circuit provides 6 gpm (22.7 lpm). A pressure reducing valve in the tool circuit limits the tool pressure. The valve can be adjusted from 1000 to 2500 psi (70 to 175 kg/cm).
CONTROL VALVES – Full pressure hydraulic control valves at the platform and turret control rotation, upper boom, and lower boom movements. The standard upper control is a Unitrol single stick. The lower controls are equipped with a selector valve to override the upper controls and also serve as the emergency stop for the upper controls.
ENGINE START/STOP – The start/stop circuit has been designed so the lift cannot be operated unless the truck ignition switch is in the “RUN” position and the master control is activated. This feature makes it difficult for unauthorized individuals to operate the lift when the truck is locked. An air cylinder at the upper controls and a toggle switch at the pedestal energize this system.
EMERGENCY POWER – The emergency hydraulic pump is driven by a DC motor, which is powered by the truck engine battery. The system is connected in parallel with the main pump and is designed for non-continuous operation. An air cylinder at the upper controls and a toggle switch at the turret are used to energize the system. This option requires the use of an additional pass in the collector ring assembly.
HOSES AND FITTINGS – The hoses, routed through the booms, are high pressure and non-conductive with swaged hose end fittings. Retainers separate the hoses inside the booms to prevent chafing and nylon sleeves are installed over hoses at points of movement. Reusable fittings can be installed if a hose is damaged.
ELECTRICAL INSULATION SPECIFICATIONS – The upper boom is tested and certified for electrical work at 46 KV and below in accordance with ANSI A92.2 Category C dielectric rating requirements. The chassis insulating system (lower boom insert) is also tested according to ANSI A92.2.
MAIN OUTRIGGERS/SUBFRAME – A short sub-frame spans between the main A-Frame outriggers and the lift. The sub-frame and outriggers are pre welded to a sub-frame and are equipped with pivot feet, pilot operated check valves, internal thermal relief valves, and separate controls. On a 32” (0..81 m) frame height, the outriggers provide 18.5” (0.47 m) ground clearance, at full extension provide 148” (3.76 m) spread, 9” (0.23 m) penetration.
AUXILIARY OUTRIGGERS – H-frame outriggers are shear-plate mounted to the frame and are equipped with pilot operated check valves, internal thermal relief valves, pivot feet, and separate controls. Outrigger dimensions vary with chassis application. The outriggers furnish up to 99 1⁄2 in. (2.5 m) of spread, 7 in. (178 mm) of penetration, and 17 in.
(432 mm) of ground clearance.
OUTRIGGER/BOOM INTERLOCK SYSTEM – The outrigger/boom interlock system prevents lift operation until the outriggers contact the ground and outrigger retraction before the aerial lift is properly stored.
SLOPE INDICATORS – Slope indicators are required on Versalift units and supplied by Time Manufacturing Co. Slope indicators shall be installed to indicate the level of the rotation bearing relative to the ground.
MANUALS – Two (2) operator’s manuals and two (2) service manuals are included.
