RATED TOTAL LOAD

The maximum load that can be applied according to the

boom length and angle. The load includes the mass

(weight) of hoisting accessories (hooks) and slinging

ropes.

RATED LOAD

A load derived by subtracting the mass (weight) of hoisting

accessories (hooks) and slinging ropes from the rated total

load, and can be hoisted.

WORKING RADIUS

A horizontal distance between the axis of slewing and the hook

centre.

BOOM LENGTH

A distance between the boom primary pin and the sheave pin

at the tip of the boom.

DERRICKING ANGLE

An angle which the boom forms with the horizon.

LIFTING HEIGHT ABOVE GROUND

A vertical distance between the hook bottom end and the

ground with the hook raised to the upper limit.
