    摘要： A shock absorber for a railcar locates within a center sill of the railcar. The shock absorber has a housing that moves relative to the center sill. A backstop is welded to the center sill for retaining the piston shaft. The backstop has a top, a bottom and two parallel sides. The height of the backstop from the bottom to the top is substantially less than the center sill. The sides of the backstop are welded to the sidewalls of the center sill in a position which provides an upper clearance between the top of the backstop and the top wall of the center sill and a lower clearance between the bottom of the backstop and the bottom of the center sill.

    摘要： A railcar cushioning device for absorbing impact between railcars is provided having a hydraulic cylinder containing hydraulic fluid. A piston locates within the cylinder and is movable relative to the cylinder between an extended position and a contracted position in response to draft and buff forces. First and second sensors are provided with the piston and cylinder for detecting movement of the piston and cylinder substantially between the contracted and extended positions. By means of a suitable logic circuit or microprocessor, the period of time that it takes for the piston and cylinder to move between the contracted and extended positions can be monitored to determine if the period of time is less than a preselected amount thus indicating that the cushioning unit has failed. A counter may also be provided to count the number of times that the cushioning unit has failed. After the number of failures reaches a selected number, an output may be provided by means or a readout display or transponder indicating that the cushioning unit has failed.

    摘要： A rail car has a sliding sill located within a fixed frame and a shock absorber for absorbing shock. The shock absorber has a housing with inner and outer chambers containing oil and gas. A piston extends from the housing. The housing has an end plate on its end which engages a frame stop. The housing has a base end which engages another frame stop. Limiting stops formed on the housing limit the amount of buff movement allowed.

    摘要： A vibratory compactor is connected to a loading boom for exerting compaction forces upon trash and the like. The vibratory compactor includes a generally circular base plate having outboard bearing members located near the periphery thereof, inboard bearing members extending across the central portion thereof stiffening the base plate, gussets connected thereto and extending toward the periphery of the base plate for stiffening the base and supporting inboard bearing members, and vibration isolating means located between the connectors used for connecting the compactor to the loading boom and the inboard and outboard bearing members.

    摘要： A railcar shock absorber has neutral position in which the piston is spaced between buff and draft ends of the cylinder. An external spring is mounted to the shock absorber. A slider rod has one end mounted to the coupling to move relative to the frame of the railcar. The spring has retainers on each end, and the slider rod passes through the retainers. One of the retainers is stationary relative to the frame. The other retainer floats relative to the frame and will abut a neutral stop of the frame when the spring is in the maximum length position. An engagement member on the slider rod will further compress the spring if a draft shock occurs from the neutral position. If a buff shock occurs from the neutral position, the engagement member moves away from the floating retainer.
