Abstract
A jaw assembly for a jaw crusher is disclosed where the assembly comprises a jaw stock (12), a wear plate (16), and a fastening device in the form of a bolt (34) with a square head (42) at one end and a washer (56) and fastening nut (52) positioned at an end opposite to the one end. The bolt (34) extends between the jaw stock (12) and the wear plate (16). The fastening device (34, 42, 56, 52) is operative to adopt a clamped configuration where the device provides a clamping force along a fastening axis to clamp the wear plate (16) at the jaw stock (12), and a released configuration where the fastening device does not prevent the wear plate (16) from being separated from the jaw stock (12). The fastening device (34, 42, 56, 52) is accessible from a direction that is transverse to that fastening axis, to enable the device (34, 42, 56, 52) to be changed from its clamped configuration to its released configuration.
