A back stop for a crane which eliminates operator's discomfort and adverse effects on surrounding environment due to generation of abnormal noise and enables greasing work to be facilitated. A back stop includes an outer casing having a base end portion turnably connected to a boom or a crane main body and an opening portion opened in the outer casing front end portion; an inner casing having a base end portion turnably connected to the crane main body or the boom and having a front end portion side slidably fitted into the outer case through the opening portion; and a greasing tube arranged in the outer casing or the inner casing. An inlet of the greasing tube is arranged outside of the outer casing or outside of the inner casing on the base end portion side on which the greasing tube is arranged. A discharge port of the greasing tube is attached to a front end portion of the inner casing.

The disclosure relates to the field of vehicle energy recovery devices, and particularly discloses a vehicle shock absorber capable of generating electricity which includes a shock absorber body, a piston rod and a bearing spring. The shock absorber body includes an inner cylinder and an outer cylinder, and an oil storage chamber communicated with an inner cavity of the inner cylinder is formed between the inner cylinder and the outer cylinder. Both ends of the bearing spring are respectively connected to an upper end of the piston rod and the outer cylinder. A bottom end of the piston rod is connected to a piston in sliding fit with the inner cylinder, and a coil is sealedly disposed in the piston. Opposite sides inside the oil storage chamber are each provided with a permanent magnet with an opposite magnetic pole, and the coil is connected to an electrode lead.

An engine mount device includes a housing, a carrier within a cavity in the housing, and a flexure flexibly connecting the carrier to the housing, with a pin disposed in a hole in the carrier to support an engine. A method of providing isolation in the engine mount device includes transmitting a force from the pin into the carrier; mechanically isolating the carrier from the housing via the flexure; and providing, via the flexure, a higher stiffness in one or more radial directions of the hole compared to a stiffness provided in an axial direction of the hole.

A linear actuator comprising a housing with a proximal end and a distal end, the housing defining a central cavity extending axially through the housing; a piston tube, where a first portion of the piston tube is slidably positioned axially in the housing, and a second portion of the piston tube extends outwardly from the distal end of the housing; an elongated rotatable screw positioned axially within the central cavity of the housing; a nut positioned within the housing and mounted about the screw, the nut configured to move axially within the housing as the screw rotates; and a spring positioned around the screw, the spring positioned within the housing between the nut and the piston tube; wherein the spring is configured to bias the piston tube away from the nut.

A shock absorber apparatus is provided that includes an upper rack frame, a middle plate, and a lower rack frame. The upper rack frame is configured to secure a bottom frame of a rack server. The upper rack frame includes a first set of rail assemblies. The middle plate includes a second set of rail assemblies and a first set of carriers corresponding with the first set of rail assemblies of the upper rack frame. The first set of rail assemblies is configured to restrict movement of the first plurality of carriers to a first axis. The lower rack frame includes a second set of carriers corresponding with the second set of rail assemblies of the middle plate. The second set of rail assemblies is configured to restrict movement of the second plurality of carriers to a second axis.

Systems, methods, and devices of the various embodiments provide a compact vibration damper configured to be remotely-tunable and/or self-tuning. In various embodiments, a flywheel may be coupled to a shaft that spins a rotary damper. A linear actuator may operate a scissor assembly that moves the flywheel thereby changing the mass moment of inertia of the spinning flywheel without changing the actual mass of the flywheel. The linear actuator may move the scissor assembly and flywheel to tune the compact vibration damper. In additional embodiments, opposing rotary springs may be coupled to the shaft that spins the rotary damper.
