摘要

PROBLEM TO BE SOLVED: To improve workability by automatizing atoring operation of a telescopic boom 6 on a car-mounted type carne installed between a driver's cabin 2 and a load-carrying platform 3 of a vehicle 1. SOLUTION: A controller 30 is constituted to output a driving signal to the winding-up side against a wich control means 17 until a spiral detection signal is input from a spiral detection means 34 in a state where a storage command signal is input from a storage command means 36, to output the driving signal to the winding-up side against the which control means 17 after the spiral dtection signal is input from the spiral detection means 34 and to output a driving signal to the derricking side against a derricking control means 16.
