Title:
CRANE, AND CRANE CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2016/158681
Kind Code:
A1
Abstract:
Provided is a crane which allows the deformation and vibration of a crane structure while traveling and while stopped to be suppressed. An inverter 11 is installed on each of travel devices 2 that are arranged in spaced and opposed relation to each other in the transverse direction x. The inverters 11, which are independent of each other, each measure the torque generated in a motor 8 connected thereto, and reduce the rotational speed instructed to the motor 8 by a controller 12 at a greater rate as the torque increases, thereby reducing the displacement in the travel direction y of the opposed travel devices 2.
