<P>PROBLEM TO BE SOLVED: To provide a snow remover capable of suppressing heat generation of a member group for electrically lifting a snow removal part without being accompanied by increase of a manufacturing cost. <P>SOLUTION: A snow remover 1 includes: a machine body 2 having crawlers 5L and 5R; a snow removal part 12 liftably supported by the machine body 2; an engine 17 for driving respective parts; a lifting cylinder 24 for lifting the snow removal part 12; a lifting lever 34 for instructing elevation, lowering and elevation/lowering stop of the snow removal part 12; a lifting operation sensor for detecting an operation of the lifting lever 34; and a control part 50 for controlling the operation of the lifting cylinder 24 on the basis of the operation of the lifting lever 34 detected by the lifting operation sensor. The control part 50 integrates a positive value when the lifting cylinder 24 is operated and a negative value when the lifting cylinder 24 is stopped, and when an integrated value reaches a prescribed value, stops the lifting cylinder 24 until a fixed period elapses. <P>COPYRIGHT: (C)2013,JPO&INPIT |
