Title:
摩耗量算出装置、異常摩耗判定装置、及びブレーキ装置
Document Type and Number:
Japanese Patent JP7262992
Kind Code:
B2
Abstract:
The present invention aims to simplify the work when replacing the brake shoe. The wear amount calculation device of this invention includes an angle sensor (89) for detecting the rotation angle position of the boom (76) that rotates with the brake shoe (40). The angle sensor (89) is installed at the connecting part between the protrusion (71A) and the boom (76) in the braking device (50). In addition, the wear amount calculation device includes a calculation unit for calculating the wear amount of the brake shoe (40). Based on the initial value of the rotation angle position of the boom (76) relative to the protrusion (71A) centered on the connecting pin (83) and the current value of the rotation angle position of the boom (76) centered on the connecting pin (83) relative to the protrusion (71A), the wear amount of the brake shoe (40) is calculated by the calculation part.
