Other standard power sources of the closed-center, variable displacement and load sensing type may be utilized. Minimum horsepower required is 35 H.P.CYLINDER HOLDING VALVESThe holding sides of all standard cylinders are equipped with integral-mounted holding or counter-balance valves toprevent sudden cylinder collapse in case of hose or other hydraulic failure. The power-out and power-downoutrigger cylinders have positive, pilot operated holding valves that open only upon command.The counter-balancevalve serves several functions. First, it is a holding valve. Secondly, it is so constructed that it will control thelowering function and allow that motion to be feathered while under load. Finally, if a hose breaks, the only oil losswill be that in the hose.ROTATION SYSTEMRotation of the crane is accomplished through a turntable bearing, powered by two high torque hydraulic disc-valvemotors through two planetary gear boxes. A fail-safe, spring-loaded brake is an integral part of each planetarygear box which provides rotational and parking brake action. Total gear reduction is 99:1.HYDRAULIC SYSTEMThe hydraulic system is a closed center, load sensing, standby-pressure system providing 20 GPM optimum oil flowat 2500 PSI. Stack type control valve with dual operational control handles located at both sides of the crane forall lift, telescope and swing functions is standard. Single control lever for each outrigger function, located on thesame side as the outrigger, is standard. System includes hydraulic oil reservoir, suction and return line filters,closed center, load sensing control valve and a variable displacement radial piston pump.SELECTED WEIGHTS OF ANCILLARY EQUIPMENTAUXILIARY OUTRIGGERS18' SUB-FRAMEPUMP & PTOMOUNTING HARDWAREOIL RESERVOIROIL (60 gallons)IMT reserves the rightto change specificationsand design without notice.1770 lbs1800 lbs140 lbs520 lbs190 lbs420 lbs

A subframe/torsion box must be used to tie the auxiliary outriggers to the crane. For each applicationcontact IMT for a weight distribution and stability analysis.NOTES:1. GAWR means Gross Axle Weight Rating and is dependent on all components of the vehicle such as axles,tires, wheels, springs, brakes, steering and frame strength meeting the manufacturer s recommendations.Always specify GAWR when purchasing a truck.2. Minimum axle requirements may increase with use of diesel engines, longer wheelbase or service bodies.Contact the factory for further information.3. Weight distribution calculations are required to determine final axle loading.4. All chassis and crane combinations must be stability tested to ensure stability per ANSI B30.22
