Hydraulic systemHydraulic system consists of pumps, control valves, motors, counter balance valves, pilot valves hydraulic reservoir & oil cooler.
Pump(s):Three variable displacement pumps driven by engine through heavy duty pump drive. Two pumps are used for luffing, traveling, main and auxiliary hoisting and third is for slewing operation.
Motor(s):Main hoisting motor  – Two speed variable piston typesBoom hoist motor – Variable piston typesAuxiliary hoist motor – Variable piston typesSlew motor  – Variable piston typesTraveling motor – Two nos. variable piston type for independent operation of both left and right track (s).
Control Varve(s);Hydraulically pilot operated spool type control valves for luffing, main hoisting, auxiliary hoisting and travelling. Lever operated control valve for slewing operation.
Oil cooler:Oil to air heat exchanger with hydraulically driven fan.
Hydraulic oil reservoir:490 ltrs capacity hydraulic tank is fitted with suction strainer, return line filter, breather cum filler, butter fly valve and drain valve.
Hoisting systemBoom hoist:Boom hoisting is achieved through a planetary reducer powered by hoist hydraulic motor and fitted with counter balance valve. Fail safe brakes are operated hydraulically and external drum locking is also provided. Single drum with 20 mm dia wire rope with a line speed of 50 mtrs / min is provided.
Main hoist:The winch drum is driven through a planetary reducer powered by hydraulic variable piston motor. Spring applied hydraulic fail safe brake along with counter balance valve is provided. External drum locking mechanism is also provided. The main drum is fitted with 22 mm dia wire rope and has a line speed of 70 mtrs/ min. and max. line pull of 12000 kgs.
Auxiliary hoist:Auxiliary hoisting mechanism can also be provided as optional feature. The auxiliary hoist is driven through a planetary reducer powered by hydraulic variable piston motor. Spring applied hydraulic fail safe brake along with counter balance valve is provided. External drum locking mechanism is also provided. The main drum is fitted with 22 mm dia wire rope has a line speed of 70 mtrs/ min. and max. line pull of 12000 kgs.
Slewing systemSlewing is achieved through planetary reducer and pinion gear powered by hydraulic motor providing 360° rotation for the complete super structure.
The heavy duty slew ring is internal geared type, and provides unlimited slewing in either direction. Spring applied hydraulic multiple disc brake is mounted on the slew gear box and mechanical swing lock is provided.
Electrical systemThe electrical system is 24V DC (negative earth) and is provided with 2 Nos 180 AH -12 V heavy duty batteries connected in series.
The electrical system comprises of ignition switch, starter, indicator light(s), working light{s), cab light(s), fan, wiper, limit switches, gauges and digital load display (LCD).
