6.F. - Page 20 of 131 Attachme A Bidder's Initials 1,150 55 The booms shall be provided with an angle indicator mounted near the operator station. A suitable boom rest shall be provided for use during transport. Boom rest shall be removable. The total weight of a standard crane shall not exceed 11,220 lbs. (includes crane, boom, ASH and subbase). Capacity: The rated capacity of the crane shall be a minimum of 20,000 lbs. @ 5 feet and 1,500 lbs. @ 50 ft. The capacities shall be obtained with the utilization of a downhaul weight that is standard equipment. The crane shall have a zero -degree lifting chart for the full horizontal telescoped boom length. Outriggers: Shall be a minimum of two (2) front horizontal out and down style outriggers. The front outriggers shall extend to maximum of 16 feet and retract to a minimum of 94". Front outriggers shall be horizontally mounted, hydraulic in and out, up and down. "A" Frame outrigger is not acceptable. Two (2) 18" x 18" outrigger pads shall be included for each side (four total), each housed in a bracket underneath (doorless drawer) or in another safe, easily accessible location. Stabilizers: The crane will be provided with rear vertical hydraulic stabilizers mounted behind the rear tires. They shall be of a box -type construction. The cylinders shall be fully enclosed to prevent debris from entering the cylinder and have an 8" DIA Steel pad at the bottom of vertical jack on each side. The stabilizers shall provide adequate ability to stabilize and level the unit for safe operation. They are to have an 8' span with 18" vertical travel. Counter weight may be required. Stabilizer gauge controls shall be included on both sides of operator. Rotation: The boom shall be capable of being rotated a minimum of 375° in not more than 36 seconds. The rotation system shall consist of a planetary gear box with a spring applied hydraulically released brake. The brake shall have the ability to slip through to reduce impact loads on the rotation system. The drive gear shall maintain full tooth contact with the rotation gear without the necessity of adjustment. Rotational force is to be no less than 152,633 in. -lbs. with breaking strength no less than 299,000 in. -lbs. The turret and main frame mounting surface for the bearing shall be machined after welding. Rotation gear is to be attached to the crane frame by use of high strength bolts for ease of service. A full circle bolt pattern between the main frame, rotation bearing and turret shall be used for equal load distribution. The rotation stop shall provide a "cushioned" or "feathered" stop to prevent shock loading of rotational components. Winch: The crane shall be equipped with a boom mounted planetary type winch. A hydraulic motor with planetary gear reduction will provide "power down" load Page 17 of 20 191
