Wheel Drive Control Device, Wheel Drive Control Method, And Program Therefor

Abstract

Disclosed is a wheel drive control device for controlling the drive of the wheel for a crane device which moves while supporting a hoist section. The wheel drive control device is provided with: a load detection unit for detecting the lifted load of the hoist section; and a torque limit value determination unit for determining the limit value of a torque in accordance with the lifted load by increasing the limit value of the torque, while the crane device is accelerating and in accordance with the lifted load, until said limit value of the torque reaches the maximum value.

Description

technical field [0001] The present invention relates to a wheel drive control device, a wheel drive control method, and a program for driving and controlling wheels of a crane device. [0002] this application claims priority based on Japanese Patent Application No. 2009-262902 for which it applied to Japan on November 18, 2009, and uses the content here. Background technique [0003] Large-scale cranes for lifting containers are installed, for example, at piers along the bay. Specific examples of the large crane include a RTG (rubber-tyred gantry crane), a container crane, and a ceiling crane installed on a ceiling of a factory room or the like. However, among these cranes, a trolley called a trolley that lifts a load and moves it moves on a rail provided above the crane to move a suspended container or the like from one point to another. For example, a place for container storage (container yard) moved from a ship to land along the bay. [0004] In this way, the trolley...

Problems solved by technology

[0007] However, in the technique of the aforementioned Patent Document 1, a large number of sensors and complex calculations are required to prevent wheel spin of the trolley, and a technique for reducing wheel spin of the trolley with a simpler configuration is required.
