| 61 | HYDRAULIC ATTACHMENT | US14374767 | 2013-03-19 | US20150027569A1 | 2015-01-29 | Oliver Preuss; Stefan Lohmann; Colin Dirr; Oleg Knjazev; Martina Jaekel; Uwe Autschbach; Markus Mellwig |
| The present invention relates to a hydraulic attachment comprising a hydraulic circuit, the attachment being a construction or demolition tool, in particular a hydraulic breaker, demolition shears, scrap shears, a pulveriser, a gripper, a crusher bucket or a compactor, which can be mechanically connected to a support device and hydraulically connected to the hydraulic system of the support device. In order to enable the hydraulic circuit to be opened quickly and safely within an attachment and, in particular, to make it possible to display the presence of a particular pressure level within a hydraulic attachment and to determine whether a dangerous residual pressure is present in the system, a hydraulic attachment is proposed that has a residual pressure display (40) which is connected to the hydraulic circuit of the attachment in a detachable or non-detachable manner. | ||||||
| 62 | Oil pulse rotary tool | US13115659 | 2011-05-25 | US08857535B2 | 2014-10-14 | Manabu Sugimoto |
| A sleeve body with bearings interposed between the sleeve body and a center shaft portion is integrally coupled to an oil pulse generator. A coupling body is rotatable together with the output portion. Balls are fitted between an outer surface of the sleeve body and an inner surface of the coupling body. Cam grooves are L-shaped in plan view, and formed in a portion of the outer surface of the sleeve body at which the balls are fitted. Rotation of the output portion is transmitted from the coupling body to the sleeve body and the oil pulse generator via the balls. When rotational speed between the sleeve body and the coupling body is different, the balls relatively turn in the cam grooves to move the coupling body forward against an urging force of the coil spring so as to relieve an impact. | ||||||

| 64 | Percussive power tool pulling device | US10604083 | 2003-06-25 | US07036211B1 | 2006-05-02 | James K. Panks |
| A pulling tool comprises an air-powered internal anvil and hammer. The pulling tool is attached to the object to be removed. The hammer is urged by pressurized air to repeatedly strike the anvil, which applies a percussive force to the object, progressively removing the object from its housing. A conventional air hammer can be modified into a tool puller by replacing the air hammer bit with a cap, and attaching the object to the rear of the air hammer through a coupler. Alternatively, a cylindrically-shaped collar is slidably secured over a conventional air hammer. A pulling bit slidably communicates with a flanged rod attached to the object to be removed. Operation of the air hammer causes the pulling bit to strike the flange, progressively removing the object from its housing. | ||||||

| 69 | Jayne impact tool | US27479D | 1971-02-25 | USRE27479E | 1972-09-19 | |
| AN IMPACT TOOL FOR LOSSENING AND BREAKING HOMOGENEOUS MATERIAL SUCH AS COMPACTED OR FROZEN EARTH, BLACK TOP AND CONCRETE. THE TOOL IS ADAPTED TO BE MOUNTED ON THE BOOM OF A BACKHOE OR THE LIKE, AND IT IS POWERED BY THE HYDRAULIC SYSTEM OF THE APPARATUS ON WHICH IT IS MOUNTED OR BY A SEPARATE SYSTEM. A TOOL ELEMENT, SUCH AS A HARDENED POINT, IS INTEGRAL WITH OR MOUNTED ON AN ANVIL ARRANGED FOR LIMITED LONGITUDINAL MOVEMENT IN A HOUSING. A HAMMER COACTING WITH THE ANVIL IS ENERGIZED VY A SPRING, PREFERABLY A PNEUMATIC SPRING. A HYDRAULIC CYLINDER MOVES THE HAMMER AGAINST THE SPRING, AND WHEN THE SPRING IS COMPRESSED IN DESIRED AMOUNT, THE PISTON ROD OF THE CYLINDER IS CAMMED AWAY FROM THE HAMMER, THEREBY PERMITTING THE SPRING TO DRIVE THE HAMMER, THEREBY PERMITTING THE SPRING TO DRIVE THE HAMMER WITH GREAT FORCE AGAINST THE ANVIL. THE TOOL IS ARRANGED SO THAT OPERATION THEREOF ACCURS ONLY WHEN THE TOOL ELEMENT OR POINT IS POSITIONED AGAINST THE WORK AND THE MOVABLE ANVIL HAS AN INWARD RELATION WITH ITS HOUSING, THEREBY PROVIDING A "DEAD MAN" CONTROL FEATURE. IN BASIC FORM THE TOOL HAS A SINGLE HAMMER AND A SINGLE CYLINDER.
MODIFICATIONS OF THE BASIC TOOL CONTEMPLATE A DOUBLE CYLINDER, SINGLE HAMMER DEVICE WHICH INCREASES THE FREQUENCY OF OPERATION BY A FACTOR OF TWO, AND A DOUBLE CYLINDER, DOUBLE HAMMER DEVICE WHICH IN EFFECT IS THE COMBINATION OF TWO SINGLE HAMMER, SINGLE CYLINDER DEVICES IN A SINGLE TOOL. |

| A method and measuring device for determining the usage rate of a breaking hammer, and to a rock breaking device. The measuring device comprises a sensor for measuring a physical phenomenon caused by the operation of the percussion device. The measuring results are processed, and they are used to determine the start and end times of the operation of the percussion device. By means of a timing device, it is possible to determine the duration of an impact cycle which is added to a time counter. The durations of impact cycles added cumulatively to the time counter indicate the total percussion time of the breaking hammer. Impact pauses between impact cycles are also monitored, and pauses shorter than a predefined time limit are taken into account as part of the usage rate. | ||||||

Method of manufacturing a hydraulic hammer using a male gauge (10) and a female gauge (8) wherein the hammer comprises a body (2) and a chuck housing (5) that are connectable by means of cooperatively formed thread fittings. In particular, the method uses a cooperatively threaded male gauge (10) and female gauge (8) to form the threads on the body (2) and the chuck housing (5) and to determine the rotational orientation of the body (2) and the chuck housing (5) relative to one another. One of the male gauge (10) and the female gauge (8) is used to measure distortion of the chuck housing (5) caused by heat treatment subsequent to the formation of the thread fitting and thereby to determine the required subsequent machining of the chuck housing (5) necessary to retain the appropriate relative rotational orientation when the chuck housing (5) is connected to the body (2). The method may comprise the steps of making and appropriately marking the male gauge (10) and the female gauge (8)
