    摘要: The hydraulically powered locking puller device comprises a base assembly (10) about a central axis, a camming assembly (70) circumferentially about the base assembly (10), and an hydraulic module (30) axially centered within the base assembly (10). The base assembly (10) has a cylindrical housing wall (12) united to an anchor ring (18) carrying at least two claw members (21) and an internally threaded cylindrical surface (19). The camming (70) assembly includes a mooring ring (60) mounted on the housing wall of the base assembly (10) for axial movement therealong and a cam ring (74) axially spaced from a coupler on the mooring ring (60). The cam (74) ring is in camming relationship to the claw members (21). The hydraulic module (30) includes a plunger (40) with a replaceable tip (44), a spring retractor (50), a carrying ring (34) for hoist movement of the puller, and threads (32) for cooperative threading with the internal threads (19) of the anchor ring (18) to fix the hydraulic module (30) against axial shift. A shoulder (17) within the anchor ring provides an abutment against which the hydraulic module (30) is lodged.
