Liftcrane : Heavy Duty Boom
Notes
1. Capacities included in these charts are the maximum allowable, and are based on machine standing level on firm supporting surface
under ideal job conditions.
2. Capacities are in metric tons, and are rated in accordance with European EN13 000 Standards in terms of machine stability and
structural strength limitations. ; each rated load capacity is based on machine's structural strength limitations.
3. Capacities are based on freely suspended loads and make no allowance for such factors as the effect of wind, sudden stopping
of loads, supporting surface conditions, and operating speeds. Operator must reduce load ratings to take such conditions into
account. Deduction from rated capacities must be made for weight of hook block, weighted ball/hook, sling, spreader bar, or other
suspended gear.
4. The maximum rated load of the auxiliary sheave is the value remaining after the 2.0 ton mass of the auxiliary sheave and the mass of
the "main hook" attached to the "boom" are deducted from the maximum rated load of the "Heavy Duty Boom Capacities."
However, the maximum rated load of the auxiliary sheave is limited to 60 tons. The operating range of the auxiliary sheave is the
range that has the maximum rated load of the main hook.
5. If the auxiliary sheave is attached, the maximum rated load of the "main hook" is the value remaining after the 2.0 ton mass of the
auxiliary sheave and the mass of the auxiliary hook attached to the auxiliary sheave are deducted from the maximum rated load of
the "Heavy Duty Boom Capacities."
6. The "working radius" is the horizontal distance from the slewing center to the center of gravity of a lifted load.
7. The boom tilt angle range is according to the working range diagram.
8. The chart below shows the number of reeled lines and the maximum rated loads. (When the wire rope length is 800 m. )
