摘要： A hydraulic damper includes a cylinder containing a hydraulic fluid and a piston affixed to a piston rod that extends out from one end of the cylinder through an end cap seal and that divides the cylinder into two chambers. The piston includes a port extending longitudinally through it where the port defines a valve seat. Inserted in the port is a spring-loaded valve member having a central bore extending longitudinally through it of a selected diameter that sets the rate of extension and return of the piston rod during use.

摘要： A dual stage vehicle ladder rack permits multiple ladders to be stacked vertically above a vehicle for transport without requiring removal of the top ladder of the stack prior to removal of a lower ladder. A lower stage is movable, independent of an upper stage, between a loading/unloading position and a stowed position.

摘要： A ladder rack assembly for a work vehicle has a stationary bed for attachment to the roof thereof. A pair of parallel, spaced apart rails has guides thereon that extend from the rails' first ends toward, but short their second ends. Rollers on side edges of a load support member ride on the bed rails. When the rollers are constrained by the guides, only translation of the load support member takes place. Upon exit of the rollers from the rear ends of the guides, both translation and rotation of the load support member can occur. A control arm is pivotally joined at one end to the stationary bed. Its free end has cam actuated latch pin assemblies attached to it that co-act with cams on the stationary bed during rearward displacement of the load support member to latch the load support member to the control arm whereby further rearward movement of the load support member causes it to tilt to a somewhat vertical position.

摘要： A firefighting apparatus comprising a controller, and a hydraulic pump driven by a power-take-off and operable to supply a hydraulic fluid under pressure. A water pumping subsystem is powered by the hydraulic fluid and operable to supply water under pressure to a conduit, wherein a flow rate of water is substantially regulated by controlling the hydraulic fluid input to the water pumping subsystem. A chemical foam subsystem is powered by the hydraulic fluid and operable to inject foam at a predetermined flow rate into the conduit, wherein the flow rate of the foam is substantially regulated by controlling the hydraulic fluid input to the chemical foam subsystem. An electrical power generator subsystem is powered by the hydraulic fluid and operable to generate electrical power, wherein the frequency and voltage of the generated power is substantially regulated by controlling the hydraulic fluid input to the electrical power generator subsystem. A hydraulic fluid cooling device receives and cools the hydraulic fluid returned from the water pumping subsystem, chemical foam subsystem, and electrical power generator subsystem. A hydraulic reservoir further stores the cooled hydraulic fluid.
