Boom elevation One double acting hydraulic cylinder with integral holding valve provides elevation
from -2,5° to +79°.
Load moment and independent anti-two block system Manitowoc ICOS color display including load moment and anti-two block
system with audio-visual warning and control lever lockout. These systems provide
electronic display of boom angle, length, radius, tip height, relative load moment,
maximum permissible load, load indication and warning of impending two-block
condition. The standard Work Area Definition System allows the operator to
pre-select and define safe working areas. If the crane approaches the pre-set limits,
audio-visual warnings aid the operator in avoiding job-site obstructions.
