Jib and boom capacities shown are maximum for each section. Do not exceed capacities at reduced radii Load ratings shown on the load rating charts are maximum allowable loads with the outriggers properly extended on a firm, level surface and the crane leveled and mounted on a factory recommended truck. Always level the crane with the level indicator located on the crane. The operator must reduce load to allow for factors such as wind, ground conditions, operating speeds and their effects on freely suspended loads. Overloading this crane may cause structural collapse or instability. Weights on any accessories attached to the boom or loadline must be deducted from the load chart capacities. Do not exceed jib capabilities at any reduced boom lengths. Do not deadhead lineblock against boom tip when extending boom or winching up. Keep at least three wraps of loadline on drum at all times. Use only specified cable with this machine. SERIES 99A WITH 44 JIB NOTE: 1. Operate with jib by radius when main boom is fully extended. If necessary increase boom angle to maintain loaded radius. 2. Operate with jib by boom angle when main boom is not fully extended. Do not exceed rated jib capacities at any reduced boom lengths. 3. Capacities do not exceed 85% stability. 4. Shaded areas are structurally limited capacities. LOADLINE EQUIPMENT DEDUCT Downhaul weight 15lb. (kg) One sheave block 35lb. (138kg) Two sheave block 3lb. (161kg) Three sheave block 5lb.

mounting configurations The configurations are based on the Series 9A with an 85% stability factor. The complete unit must be installed in accordance with factory requirements and a test performed to determine actual stability and counterweight requirements since individual truck chassis vary. *88 LBS SFO *88 LBS *88 LBS SFO 74" (1879 mm) 3" (76 mm) 192" (4876 mm) 3" (76 mm) 192" (4876 mm) 3" (76 mm) 1" (67 mm) *95 LBS (439 kg) *95 LBS (439 kg) Estimated Average Final Weight...4,9 lb (18 1 kg) This configuration allows the installation of the 99A or 969A on a chassis by using a subbase for a 2-ft (6.1-m) bed or a different subbase for a 22-ft (6.71-m) bed. This mount requires front stabilizer for full capacity 36 around the truck. Front stabilizer gives the machine a solid base, helping the operator control loads. Notes: Gross Vehicle Weight Rating (GVWR) is dependent on all components of the vehicle (axles, tires, springs, frame, etc.) meeting manufacturers recommendations; always specify GVWR when purchasing trucks Diesel engines require a variable speed governor and energize-to-run fuel solenoid for smooth crane operation; electronic fuel injection requires EET engine remote throttle All mounting data is based on a National Series 9A with an 85 percent *Estimated axle scale rates prior to installation of crane, stabilizers and subbase for 85% stability.
