ABSTRACT:
This invention relates to a wear-parts system of teeth for earth-moving machine shovels, mounted at the front of the shovel and comprising several loosely interconnected parts such as tooth points (1), adapters or holders (2, 9), cutting edge protectors (11) etc. The interconnection of these parts is carried out by means of interacting male and female formed parts (15, 16, 19, 20 and 13, 14, 21, 22). The parts are locked in the assembled position by means of specially formed locking wedges (7) fitted at right angles to the assembly direction. Openings are provided in the various parts for the locking devices.
