3.2.5.2 Boom elevation shall be controlled by a single lift hydraulic cylinder for boom angle range from -1.5 degree below horizontal to +82 degree above horizontal. The boom elevation cylinder shall be equipped with a safety valve.

3.2.5.3 Crane shall have a load moment and anti-two block system with audio/visual warning system, and control lever lockout. System shall provide graphic display of boom angle, length, radius, tip height, relative load moment, maximum permissible load, load indication and warning of impending two-block condition with lock-out hoist function. Crane shall also have a working range limiter.

Cab shall include air conditioning, independent diesel cab heater, tinted safety glass adjustable operator’s seat, opening windows at side and rear, hinged windshield with wiper, sun visor and window shade.

Cab shall have additional cab mounted work light and strobe light.

3.2.5.5 The swing system shall consist of planetary gear boxes with fixed displacement axial piston motor that is infinitely variable to 1.3 rpm.

System shall be a continuous free swing type with a foot operated switch.

3.2.5.6 Main and auxiliary hoists shall be powered by axial piston motor with planetary gear and brake. Both the main and auxiliary hoist shall be equipped with cab drum rotation indicators. Main hook block shall be a duplex type hook at a minimum of 135 ton (US) and auxiliary hook block at a minimum of 35 ton (US). Headache ball shall be included in package.

3.2.6 Carrier:
