Treadmill Raising & Lowering / Improved Treadmill

A hydrotherapy apparatus (1) comprises a tank (10); a conveyer (30) with a conveyer frame (34) and drum (38) mounted within the tank (10), and an actuator (200) comprising: a guide (202) mounted on an end region of the conveyer frame (34), the guide (202) comprising a first portion (202a) and a second portion (202b) angled downwards with respect to, and closer to the drum (36) than, the first portion; a glider (204) arranged to be received by the guide (202); and an actuator shaft (208) arranged to move the glider (204). The conveyer (30) is arranged to be rotated around the axis of the drum (36) by the actuator shaft (208) moving the glider (204) along the guide (202). The hydrotherapy apparatus (1) may comprise a lifting arm (80) rotatably connected to the conveyer frame (32), at a position spaced from the drum (36), at a first end region of the lifting arm (80), and arranged to be driven by the actuator (200) so as to rotate the conveyer (30) further.
