The steel quality is selected in accordance with the classification societies recommendation to obtain necessary ductility for the lower temperature design limit.
All important weldings are carried out in accordance with welding procedure.
After welding a certain amount of NDT control is carried out. Boom meterial is high Steel (Yield Stress 350-700 N/mm2) and boom type is lattice. Foundation is designed according to max. load.
SA 2,5 sand blasting and metalizing before one coat, two pack epoxy primer.
Full vision, all steel fabricated with acoustical lining and tinted safety glass throughout.
Deluxe seat incorporates armrest-mounted electric dual-axis controllers.
Dash panel in-corporates gauges for all engine functions. Other standard features include: hot water heater , cab circulating air fan, sliding side and rear windows, sliding skylight with electric wiper and sunscreen, electric windshield wash/wipe, fire extin- guisher and seat belt.
Standard “Graphic Display” 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.
