Model 4040C 22.8' - 39.8', 2-Piece Boom Standard Specifications

• Boom: The 22.8' to 39.8', two 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 49.5'. Elevation -3 to 80 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 both sides at the rear. Boom controls are at the operators cab. All controls are fully proportional.
  
  
• Operators Cab: Aluminized steel construction. Features include slide back door, tilt open sunroof, 5 way adjustable seat, windshield wiper, dome light, fan, multi-function joystick controls, engine on/off, and foot throttle. A pull out access platform is also included.
  
  
• Hydraulic System: Hydraulic system includes transmission mounted PTO, gear pump, and hydraulic reservoir.
  
  
• Outriggers: Computer optimized outrigger system features 18' spread, out and down type front and rear outriggers. Individual controls for each function allow ease of set upon uneven terrain. Firm footing is achieved by means of 12" diameter aluminum pads. This arrangement also minimizes chassis frame rail requirements.
  
  
• 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 non-skid steel deck with access ladders, steel side rails, headache rack, boom rest, and all DOT required lighting. 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 standard (up to six parts available)
  Rope: 385' - 1/2" diameter, 6x25 FW, IWRC, EEIPS
  Load Block: 20-ton, double sheave, roller bearings with swivel hook and safety latch
  
  
• One operation and maintenance manual.
