WORK MACHINE

PROBLEM TO BE SOLVED: To provide a work machine capable of quickly illuminating a destination of the work machine as a revolving speed of a revolving body increases. SOLUTION: A first table 45 for providing a factor k1 corresponding to revolving pilot pressure Pp, a reference turning angle θs, a reference rotating speed ωs and an automatic control program 47 for designating a procedure for calculating a target turning angle θ1 and a target rotating speed ω1 from these, are stored in a storage part 43 of a control device 40. An arithmatic operation part 42 performs an arithmetic operation for increasing the target turning angle θ1 and the target rotating speed ω1 of a motor 15 being a driving source of a movable lighting system 12 as the revolving pilot pressure Pp detected by first and second pilot pressure sensors 20 and 21 increases. A second table 46 is stored in a storage part 44, and the target turning angle θ1 and the target rotating speed ω1 are corrected in response to an actual revolving speed ωt detected by a revolving speed sensor 22.
