Mobile crane XCR55L4

for constructionrough terrainlifting

1）XCR55L4 is widely used for lifting operations in oilfields, mines, road and bridge construction, etc. （2）Large displacement dual-variable plunger pump with confluent main valve adopting XCMG patented technology integrated, leads to improvement by 13% in operation efficiency, which takes the lead in the industry. （3）Large power engine + low speed large torque transmission system with hydraulic torque converter; acceleration performance is improved by 10%, the max. travel speed is 35 km/h and the max. grade ability is 70%; the min. turning radius is only 6 m, the smallest in the industry, contributing to excellent maneuver ability and quick job site transfer. （4）New energy-saving hydraulic system with double-variable pump combined with a valve-controlled load-sensing system. The fuel consumption under different working conditions can be reduced by 10%~15%. （5）Torque converter with lockup function, low speed large torque, high speed and high efficiency, and driving fuel consumption is reduced by 20%. （6）4-section boom of 36.5 m is the longest in the industry, the length of boom and jib can reach 52.5 m after jib is installed. （7）Two jib sections of 9.2m-16m , with 0°, 15° and 30° jib offset angles. （8）Max. single line pull is 51 KN. （9）Max. hoisting speed (single line, no load, 4th layer) is 150 m/min. （10）Slewing speed 0-2 r/min. （11） 163kW large power engine +hydraulic transmission system with low speed and large torque. The acceleration performance is improved by 10%, with high speed and high efficiency; 6 forward gears and 3 reverse gears are available with quick transfer.
