METHOD OF ASSEMBLING AND/OR DISASSEMBLING HYDRAULIC CYLINDER OPERATORS OF SUBSTANTIAL DIAMETER

摘要

1. Method of installing and/or removing hydraulic cylinders in particular those of substantial diameter, characterized in that firstly the vertical orientation of the cylinder or upper prop of the hydraulic cylinder being mounted or dismounted is established in relation to the transverse axis of the installation trolley, the cylinder or the upper prop is clamped in the jaws of the installation trolley in the vertical position, and next to the cylinder or the upper prop which remains in initial position with the installation trolley at least the piston rod is conveniently inserted, and next the cylinder or the upper prop or the whole hydraulic cylinder is moved along a straight line under the vertical pressure axis, it is fixed on the floating support of the bottom trolley, and next the cylinder or the upper prop of the hydraulic cylinder being installed or removed is supported from the bottom, and in case of a hydraulic cylinder being installed a force is directed from the top on the piston rod and other components of the hydraulic cylinder, the piston rod and other components of the hydraulic cylinder that require force are forced in.2. Apparatus for installing and/or removing hydraulic cylinders comprising an installation trolley, characterized in that it has a pole equipped at its bottom with angle struts (1) and seated on a bottom plate (2) joined in a separable manner with a foundation (4), and equipped at its top with a boom (5), whereas in its central part, in front and on both sides, the pole is equipped with non-even-armed angle bars (6) which constitute the raceways for vertical trolley joined at its top by means of a hydraulic cylinder (7) with the boom (5), and coupled at its bottom with the horizontal trolley, whereas below the raceway of the vertical trolley the pole is equipped with a bracket (8).IMAGE
