ANSI B30.22 crane rating (ft-lb) is the rated load (lb) x the respective distance (ft.) from centerline of rotation with all extensions retracted and the inner and outer booms in a horizontal position. ** Allow an additional 2'' between the cab and crane base for swing clearance. • Capacities (for above charts) through geometric range are limited to those shown in horizontal position. • Loads shown are based on crane structural or hydraulic capability. Before lift is made, stability must be checked per SAE J765A. • Working loads will be limited to those shown. Deduct the weight of loadhandling devices. • Winch-lifting capacity is limited to those shown. Maximum 2,500 lbs. for one-part line. 3000 Articulating Crane Minimum Chassis Specifications Minimum Chassis Specifications Performance Characteristics Rotation 400˚ (7.0 rad) 35 seconds Inner Boom Elevation -45˚ to +75˚ (-0.8 to +1.3 rad) 13 seconds Outer Boom Articulation 139˚ (2.4 rad) 14 seconds Extension 36'' (91.4 cm) 8 seconds Outrigger Stroke 28-3/4'' (0.7 m) 5 seconds Power Source Integral mounted hydraulic pump and PTO application. Other standard power sources may be utilized. Minimum power required is 10 horsepower. Cylinder Holding Valves The holding sides of all standard cylinders are equipped with integral mounted holding or counterbalance valves to prevent sudden cylinder collapse in case of hose or other hydraulic failure. The inner cylinders have single pilot-operated counterbalance valves while the outer and extension boom cylinders have double counterbalance valves. The counterbalance valve serves several functions. First, it is a holding valve. Second, it is so constructed that it will control the lowering function and allow that motion to be feathered while under load. Finally, if a hose breaks the only oil loss will be that in the hose. Rotation System Rotation of the crane is accomplished through a turntable bearing with external worm gear, powered by a high-torque hydraulic motor through a self-locking work. Total gear reduction is 73:1. Hydraulic System The hydraulic system is an open-centered, full-pressure system, requiring 5 gpm optimum oil flow at 2,700 psi. Six-spool, stack-type control valve with dual operational handles located at both sides of crane for convenient operation. System includes hydraulic oil reservoir, suction-line strainer, pump, 8-section control valve, return-line filter and all hoses and fittings.

(3,402 kg) * Allows lifting full-capacity load in a 360˚ arc when crane is installed immediately behind the cab. Great care should be taken when swinging the load from rear of vehicle to front of vehicle since the front axle springs will compress, thus affecting the levelness of the vehicle. 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. 3000 Articulating Crane Geometric Configurations Stowed Position and Outrigger Dimensions Manufacturer’s Limited Warranty Coverage Products manufactured by IMT are warranted to be free from defects in material and workmanship, under proper use, application and maintenance in accordance with IMT’s written recommendations, instructions and specifications as follows: Iowa Mold Tooling Co., Inc. 500 Highway 18 West P.O.
