Abstract
The present disclosure generally relates to apparatus, systems, and kits of parts for knock-down heavy-duty transportable torque tool assemblies capable of onsite field-servicing of high-pressure heavy-duty hydraulic cylinders used in heavy-duty construction equipment and industrial machinery. The embodiments disclosed herein pertain to assemblies comprising modular knock-down components that may be mounted onto the bed of a field service truck and configured as needed to provide loosening and retorquing of piston-retaining nuts.
Claims6
A transportable system for loosening and retorquing hydraulic cylinder piston-retaining nuts on hydraulic cylinders, the system comprising:
- a transportable, knock-down, torque tool apparatus including,
- a torque head assembly being demountably engageable (i) with the hydraulic cylinder piston-retaining nut, and (ii) with a torque tool hydraulic cylinder;
- a slide bed assembly being demountably engageable (iii) with a work surface, and (iv) with a barrel lug end of the hydraulic cylinder, the slide bed assembly resting over the work surface;
- and
- a hydraulic cylinder support assembly being demountably engageable (v) with the slide bed assembly, and (vi) with the torque tool hydraulic cylinder, an end of the hydraulic cylinder support assembly resting over a surface different in elevation from the work surface;
- the torque tool hydraulic cylinder;
- a hydraulic power unit;
- a battery for powering the hydraulic power unit;
- a pressure gauge for communication with the torque tool hydraulic cylinder and the hydraulic power unit;
- and
- a plurality of high-pressure hydraulic hoses for interconnecting the torque tool hydraulic cylinder and the hydraulic power unit.
