Deduct 120 lb from all "on rubber" capacities whenboom extension is stowed on base boom.

Maximum hydraulic pressure is 3,000 psi.

Personnel bucket capacity, outriggers extended,300 lb per bucket, 600 lb total. The booms on thisunit are all steel and have no line voltage rating.

Deck capacity 12,000 lb (centered over axle).

Capacities below bold line are limited by tipping.Other capacities are limited by structural or hydrauliccapability.

All capacities apply to operation on firm level surfaces.

The load hoist line on this unit must be 9/16" diameter6 x 37 IWRC EIP wire rope or equivalent with aminimum breaking strength of 31,500 lb.

Operation:

Carry capacity speed limit 3 mph.

1. Read and understand owners manual before operating the crane.2. Check level of hydraulic oil daily.3. Check unit for visible effects and loose parts.4. Start engine.5. Set vehicle park brake securely.6. Extend outriggers to solid footing.7. Operate all hydraulic controls slowly and deliberately for smooth motion.

Capacities on outriggers are 85% of tipping loads.Capacities on rubber are 75% of tipping loads.

Use single part load line for loads to 9,000 pounds.Use two part load line for loads to 17,000 pounds.

1. A freely suspended load is a load hanging free with no direct external force applied except by the hoist rope.

2. Crane load ratings are based on the crane being leveled and standing on a firm, uniform supporting surface.

3. Use of jibs, lattice-type boom extensions, or fourth section pullouts extended is not permitted for pick-and-carry operations.

4. The use of more parts of line than required by the load may result in having insufficient rope to allow the hook to reach the ground.

5. Do not elevate the boom above 60° unless the boom is positioned in-line with the crane’s chassis or the outriggers are extended. Failure to observe this warning may result in loss of stability.

6. CRANE LOAD RATINGS MUST NOT BE EXCEEDED. DO NOT ATTEMPT TO TIP THE CRANE TO DETERMINE ALLOWABLE LOADS.

7. When either radius or boom length, or both, are between listed values, the smaller of the two listed load ratings shall be used.

8. Do not operate at longer radii than those listed on the applicable load rating chart (cross-hatched areas shown on range diagrams).

9. The boom angles shown on the capacity chart give an approximation of the operating radius for a specific boom length. The boom angle, before loading, should be greater to account for boom deflection. It may be necessary to retract the boom if maximum boom angle is insufficient to maintain rated radius.

10. Power telescoping boom sections must be extended equally.

11(a). Rated loads include the weight of hook block, slings, and auxiliary lifting devices. Their weights shall be subtracted from the listed rated load to obtain the net load that can be lifted.

11(b). When lifting over the jib the weight of any hook block, slings, and auxiliary lifting devices at the boom head must be added to the load.11(c). When jibs are erected but unused add two (2) times the weight of any hook block, slings, and auxiliary lifting devices at the jib head to the load.

12. Rated loads do not exceed 85% on outriggers or 75% on tires, of the tipping load as determined by SAE Crane Stability Test Code J765a. Structural strength ratings in chart are indicated with an asterisk(*).

13. Rated loads are based on freely suspended loads. No attempt shall be made to drag a load horizontally on the ground in any direction.

14. The user shall operate at reduced ratings to allow for adverse job conditions, such as: Soft or uneven ground, out of level conditions, high winds, side loads, pendulum action, jerking or sudden stopping of loads, hazardous conditions, experience of personnel, two-machine lifts, traveling with loads, electric wires, etc.

15. The maximum load which can be telescoped is not definable, because of variations in loadings and crane maintenance, but it is permissible to attempt retraction and extension if load ratings are not exceeded.

16. Load ratings are dependent upon the crane being maintained according to manufacturer’s specifications.

17. It is recommended that the load handling devices, including hooks and hook blocks, be kept away from boom head at all times.

18. Do not lift with outrigger beams positioned between the fully extended and intermediate (pinned) positions.
