Apparatus for covering product containers loaded in a cargo container is disclosed. The apparatus includes an automated cord reel including a spool and a motor configured to drive the spool. The spool when activated reels in a cord attached to a cargo blanket to spread the cargo blanket over product containers in the cargo container in a smooth motion and/or relatively constant speed to prevent snagging on the product containers. The automated cord reel may be configured as a mobile unit with wheels. A brake system may be provided to prevent movement of the automated cord reel during operation. The automated cord reel may have a battery to provide electric power to the motor. A magnetic floor brake may be configured to hold a cart body in a selected position.

A car having: a frame; four wheels, which are mounted on the frame in a rotary manner; a body, which covers the frame; at least one compressed air tank; and at least one gas pusher, which is connected to the compressed air tank, is integral to the frame and has a plurality of nozzles, which face outwards, can be activated in order to generate respective air jets, are arranged parallel to and beside one another, have the same orientation and are sized so as to generate different pneumatic thrusts given the same pressure of the compressed air flowing in; a pressure sensor, which determines a pressure inside the compressed air tank; and a control unit, which activates the plurality of nozzles in a coordinated manner so as to generate, as a whole, a desired pneumatic thrust based on the pressure inside the compressed air tank.

The present disclosure discloses a suspension device of a monorail crane and a monorail crane. The suspension device the suspension device comprises a suspension box and at least one set of suspension wheels; the suspension box is provided with a receiving groove for receiving at least one set of the suspension wheels; the receiving groove is provided with a first suspension wheel and a second suspension wheel; a first gap is formed the first suspension wheel and the second suspension wheel; the monorail comprises at least a first track on which the first suspension wheel is placed and a second track on which the second suspension wheel is placed; a spacer is provided between the first track and the second track; the first gap can accommodate at least the spacer; the suspension devices each further comprises a braking mechanism fixed to the suspension box.

Braking systems for aircraft are disclosed. An example braking system includes a brake pad movably coupled to a lower section of a fuselage of the aircraft. The brake pad is movable between a stowed position and a deployed position. An actuator is configured to deploy the brake pad from the fuselage during an emergency braking event. The brake pad to engage a surface of a runway and increase frictional force to reduce a speed of the aircraft during the emergency braking event.

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 system for decelerating a vehicle includes a powered driver and an anchor supported by the powered driver. The powered driver configured to be movably coupled to a chassis of the vehicle. The powered driver is also configured to propel the anchor from the powered driver into a road surface to secure the vehicle to the road surface for decelerating the vehicle.
