WEIGHT REDUCTION FOR LOAD HANDLING DEVICES
HOOK BLOCKS
30 Ton, 2 Sheave..................600 Lbs.
12 Ton, Headache Ball..........274 Lbs.

NOTE: All load handling devices are considered part of the load and suitable allowances must be made for their combined weight.

 

 LINE PULL & REEVING
CABLE SPECS.- 3/4 in. Trulay 18x7 IPS, IWRC
PERMISSIBLE LINE PULL 15,000 Lbs.
For multiple part reeving, use one line for each 15,000 lbs. of load or portion thereof.

 

NOTES TO LIFTING CAPACITIES

  1.  The Crane must not be operated and must be retracted in winds over 45 m.p.h. (72 Km/h)

  2. Rated lifting capacities are based on freely suspended loads. They are the maximum covered by the Manufacturer's warranty with the machine leveled and standing on a firm supporting surface. Ratings are based on rear outriggers being extended to their maximum positions with safety screws turned down. Mast cylinder pressure must be maintained at a minimum of 1,800 p.s.i., (122.5 bar) with the exception of first operating height.

  3. Practical working loads for each particular job shall be established by the user; depending on operating conditions; including the supporting surface and other factors affecting stability, hazardous surroundings, experience of personnel handling of loads, etc.

  4. Operating radius is the horizontal distance from the axis of rotation to the centerline of the hoist line or tackle with loads applied.

  5. The jib may be used for single line lifting crane service only.

  6. For concrete bucket operation, weight of bucket and load must not exceed 90% of rated lifting capacities as indicated by warning light.

  7. Loads over 7500 lbs. (3400 Kg.) must be handled only in low speed.

  8. Load block must be centered on boom for multiple reeving.

  9. Always lift load clear of ground with hoist, as booming up is not protected against overloading.

  10. Load Moment Indicator and travel limit switches are to be used as an assistance to the operator and are not to be considered as safety protection.

NOTES TO JIB CAPACITIES

  1. Side loads must not exceed 2%.

  2. For 20 ft. (6m.) jib capacities in shaded area have no overload protection.

  3. 70 ft. (21m) jib not to be used when wind exceeds 35 mph (56Kmh)

  4. All notes are to be applied in addition to and/or in conjunction with standard notes to lifting capacities.
