Hydraulic Device With Heating Element

摘要

A hydraulic device is provided capable of moving heavy loads along a slotted track. The hydraulic device has a cylinder and piston unit, a jack that is connected to one or more ratcheting claws, and a sliding member having slots for placement of one or more ratcheting claws. To prevent brittle fracture of the hydraulic device during the movement of heavy loads under extreme cold conditions, the hydraulic device has a chamber for placement of heatable members that heat various elements of the hydraulic device, thereby reducing the likelihood of brittle fracture of the hydraulic device during operation. The hydraulic device may have one or more pairs of tandem ratchet claws that evenly distribute load forces along the slotted track. The device may also have detachable side weldments that hold the jack and claws for easy placement and removal of the device on a beam.

主权项

1. A hydraulic device for moving skids upon a support foundation of the type having a longitudinal beam with a series of longitudinally spaced recesses comprising:
a) a hydraulic cylinder and piston unit; b) a jack connected to said cylinder and piston unit on one end; c) a dog rotatably mounted to said jack and adapted to be received within a spaced recess of the beam; d) a sliding member capable of slidably engaging with the longitudinal beam, said sliding member having a slot adapted to allow rotation of said dog within said slot; e) a chamber disposed within said sliding member capable of receiving a heatable member, thereby raising the temperature of the device and reducing the likelihood of brittle fracture and ice buildup on the device and/or beam;
whereby when said dog is received within a recess in the beam, said dog allows forward, but not backward linear movement of said hydraulic device along the beam, thereby allowing said hydraulic device to ratchet forward in a step-by-step manner.
