Japanese Patent JP2014527133
Kind Code:
A
Abstract:
The present invention relates to an excavating tooth for construction machinery and a method for replacing an excavating tooth of construction machinery. The excavating tooth is provided with a working end and a mountable end. The mountable end defines a means for receiving an adaptor mounted on a work tool. The working end defines a bore. A wear indicator is located within the bore and provided with a length that is less than an unworn length of the working end and a color that visibly contrasts with a color of the working end. As the excavating tooth is worn down during use, the wear indicator becomes visible to provide a visual indication of the need to replace the excavating tooth.
