| 20110272656 | HOIST ROPE EQUALISER - A load equaliser for supporting a drag line bucket from first and second cables is disclosed. The load equalizer has a main body having a central portion and side portions providing respectively first and second clamps for clamping end portions of the first and second suspension cables. A rotatable mounting is provided in the suspension central portion of the main body. A link body is suspended below the main body and connected thereto through the rotatable mounting whereby freedom of relative rotational motion is provided at least about an axis substantially at right angles to the direction between the clamps. The rotatable mounting is in a zone extending substantially between the clamps. | 11-10-2011 |
| 20100043668 | RAIL CAR SUSPENSION DAMPING - A freight rail car suspension has independent but co-operating springs; a first spring is load carrying and has a variable damping function and a second control spring operates on a friction shoe to apply a constant damping component. A practical embodiment has a friction shoe engaged for vertical displacement by the first spring which is mounted on a side frame and the second spring is obliquely arranged between the bolster of the bogie and the friction shoe, which has guides to cause it to move into greater frictional engagement upon load being applied through the spring. This arrangement provides a dual damping characteristic involving both constant damping and variable damping forces. | 02-25-2010 |
| 20090200817 | AXLEBOX RETAINER KEY, AN ASSEMBLY INCLUDING THE KEY AND A METHOD OF FASTENING THE KEY - An axlebox retainer key ( | 08-13-2009 |
| 20090196683 | LOCKING CONNECTOR SYSTEM - Components for use in a locking connector system, such a heavy duty shackles, comprise a retainer, a body structure and pin which is axially moveable into a receiving cavity of the body structure, the body structure having a transversely directed cavity interconnecting with the cavity and have a latching shoulder. The retainer has a body, a latch element associated with the body and adapted to move into a space adjacent the latching shoulder of the aperture when the retainer is inserted into the transverse aperture to retain the retainer in its aperture and the body of the retainer having a projecting portion for location adjacent the surface portion of the pin for restraining the pin from removal when the retainer is inserted, the retainer further having a latch actuator which is displaceable in the body from a released position to an engaged position for moving the latch element from its retracted position to a latching position, and the latch actuator further having releasable retention means for retaining the latch actuator in the engaged position but, on application of a retraction force, adapted to release the latch actuator to permit its return to its retracted position, thereby allowing return of the latch element to its retracted position, whereby the retainer may be removed from the aperture and the pin removed from the cavity. | 08-06-2009 |
| 20090139118 | DRAGLINE EXCAVATOR BUCKET - A bucket for a dragline has a pivoted mounting by having two spaced pivotal arms, typically of arcuate or cranked form, pivotally connected to the outside of a rear wall of the bucket about pivot axes extending transverse to the bucket and below the upper rim of the bucket whereby pivotal connections at the upper end of each pivot arm may be disposed over the rim and within the bucket zone. Thus the pivot arms may be moved in use through greater than 90° from a position in which the bucket is vertically suspended. The pivot arms act to spread splayed hoist chains without a spreader bar. | 06-04-2009 |
