Model 5555R 23.8' - 54.8', 3-Piece Boom Standard Specifications

• Boom: The 23.8' to 54.8', three section boom features full hydraulic extension and retraction. Its welded steel box construction has replaceable wear pads and bushings. A 10" bore vertical luff cylinder increases load space and capacity at low boom angles. Maximum tip height is 63'. Elevation 0 to 81 degrees.
  
  
• Boom Tip: Three sheaves with roller bearings, cable stays, and pad eye for wedge socket provide the ability to reeve from 1 to 6 parts of line without requiring attachment of snatch blocks. Boom tip has quick reeve design that does not require removal of wedge socket to change parts of line. The use of non-metallic sheaves reduces boom weight and increases cable life.
  
  
• Rotation: A 39" diameter swing bearing is driven by a planetary gearbox with integral brake. The standard hydraulic and electric rotary swivels provide 360 degree continuous rotation. All components are accessible from the top of the deck for ease of maintenance.
  
  
• Controls: Outrigger controls are operated from the ground on the left side at rear. Boom controls are at the operators platform. All controls are fully proportional. Standard equipment includes radio anti-two block indicator with audio alarm and function shutdowns.
  
  
• Operators Platform: The open, ride-around platform includes a control console, horn, adjustable seat, and foot throttle.
  
  
• Hydraulic System: Hydraulic system includes transmission mounted PTO, tandem gear pump, and hydraulic reservoir.
  
  
• Outriggers: Standard 18' spread, out and down type outriggers, at front and rear, allow ease of set up on uneven terrain. Firm footing is achieved by means of 24" diameter removable aluminum pads on the rear and with 12" fixed pads at the front.
  
  
• Subframe: A high capacity torsion box connects the crane and outriggers into an integral structure designed to withstand all loads produced during crane operation. The design does not rely on the truck chassis for strength which allows for mounting on a lighter and more economical truck. The clamp-type mounting requires no welding or drilling on the chassis rails and maintains full factory warranty.
  
  
• Body: A 1" hardwood bed, up to 22' in length, mounts flush with the top of the subframe on steel cross members spaced at 18". Steel side rails, headache rack, boom rest, access ladders, an 18"x48" tool box mounted on the truck's chassis, pad racks and all DOT required lighting is included. All components are pre-painted in customer's choice of colors with epoxy primer and polyurethane topcoat prior to assembly to ensure maximum protection.
  
  
• Load Chart: Each crane is load and stability tested before completion. This results in an individual load chart for each crane without requiring a minimum chassis weight or the installation of ballast.
  
  
• Winch and Reeving: Standard winch has variable speeds, power up and power down, planetary drive with spring applied, hydraulically-released brake.
  Maximum base layer line pull: 12,000 lbs.
  Maximum top layer : 115 ft./min
  Reeving: Four parts of line
  Rope: 384' - 1/2" diameter, 6x25 FW, IWRC, EIPS
  Load Block: 15-ton, double sheave, roller bearings with swivel hook and safety latch
  A 40,000 lbs. lift package is available as an option.
  
  
• One operation and maintenance manual.
