The invention discloses a brakeable transportation ore cart for mine mineral transportation, which comprises a base. Hydraulic rods are symmetrically fixed to the left and right ends of the base. The hydraulic rod is provided with a support beam for installing a motor. The motor is mounted on the beam. A moving first gear is mounted on the beam, and a hopper is rotatably installed through a rotating shaft. A second gear meshing with the first gear is fixedly mounted on the rotating shaft. A telescopic plate supported by a first spring is provided at the bottom of the hopper. Drive the hydraulic rod to make the entire hopper rise, and the third guide rod in contact with the lower end of the hopper moves upward along the sliding groove under the action of the left-right symmetrical fourth spring, thereby driving the fourth guide rod to move upward and the fourth guide rod. The fifth gear connected at the end is moved upward. Under the action of the third rack and the fifth gear meshing with each other, the fifth gear moves counterclockwise to drive the fourth gear meshed with the fifth gear to move downward.

A brake for use with a shock testing machine, the brake including: a brake material for generating a frictional force to stop a test platform when the brake material is urged against an opposed braking surface; links for rotatably connecting the brake material to the test platform; a biasing spring to bias the brake material towards the braking surface; a restraint mechanism for restraining the braking material, against a biasing force of the biasing spring, in a retracted position where the braking material is separated from the braking surface; and a release mechanism for releasing the restraint of the release mechanism to bias the brake material against the braking surface; wherein the links are configured such that relative movement between the brake material and braking surface while the brake material and braking surface are engaged causes a frictional force between the brake material and braking material to increase.

A rail brake system that may be attached to the undercarriage of a hirail vehicle or other rail vehicle or rail equipment and that includes one or more braking calipers that can be deployed downwardly and used to releasably clamp the heads of one or more rails of a railroad track in order to dynamically brake or statically secure the vehicle or equipment in place in relation to the railroad tracks on which the vehicle or equipment is positioned.

Electromechanical actuator mechanisms for storm brakes are provided. The actuator mechanisms generally comprise an electro-mechanical release system and a permanent magnet eddy current brake system with adjustable air gap for varying brake setting time, and for energy dissipation of the storm brake main spring force or weight.

A linear clutch includes a main body engaged with a locking assembly. The locking assembly includes a spring and a wedge configured to engage the spring. The wedge includes a first surface and a second surface opposite the first surface, with the second surface including a taper configured to engage a taper on a wall section of the main body. The locking assembly also includes a roller bearing assembly configured to fit within the tapers of the first wedge and the main body. Furthermore, the locking assembly includes a lever configured to engage the wedge and to move between an unlocked position and a locked position.

A self-locking anti-slip rail braking device is provided. The rail braking device includes a ladder-shaped support, a lifting unit, a roller-and-wedge plate mechanism, a roller support, and a rail clamping unit. The ladder-shaped support is connected under a surface of a balance beam of a port facility, and is connected at a middle part thereof with the lifting unit. A lower end of the lifting unit is hinged to two sides of the roller support. The roller support is provided on an upper end surface thereof with the roller-and-wedge plate mechanism, and is provided at a middle part thereof with the rail clamping unit. An upper end of the rail clamping unit serves as a force application end and is configured to match the roller-and-wedge plate mechanism, and a lower end of the rail clamping unit serves as a rail clamping end corresponding to two lateral sides of a rail.
