SLINGING DEVICE AND CRANE SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To safely conduct slinging work.SOLUTION: A slinging device 1 includes a frame assembly 20 which is connected with a lower end of a wire 120 suspended from a crane through a connection member 10. A pin 40 connected with a suspending piece 210 is supported on the frame assembly 20 so as to move in a horizontal direction. The slinging device 1 further includes a pin driving mechanism 30 which drives the pin 40. The pin driving mechanism 30 includes: a motor 32; a lead screw mechanism 35 which converts rotation of the motor 32 into linear motion; a piston 34 which is moved forward and rearward by the lead screw mechanism 35; and an arm 36 which connects the piston 34 with the pin 40.
