A portable descent platform for users descending from a rope or elastic cord. The descent platform is engaged upon a planar bed of a powered motor vehicle in a pivoting engagement allowing extension of the platform from the vehicle and numerous angles. The platform may have a first portion in a translational engagement with a second portion to allow for distance adjustment of a distal edge of the platform toward and away from the vehicle and may also include elevational adjustment of the height of the platform.

A transport device includes a main body section, a base connected to the main body section, a wheel connected to the main body section for causing the transport device to travel, a drive module for driving the wheel, and a sensor that detects a state of the transport device, wherein a posture of the main body section is controlled using an output of the sensor such that the center of gravity of a mounted object approaches the center of gravity of the transport device.

A vehicle tilting device for tilting a delivery vehicle for increasing access to items from a storage container transported on the delivery vehicle includes a base structure and a tiltable platform connected to the base structure. The tiltable platform includes guiding features adapted to guide the delivery vehicle onto the tiltable platform, and a tilting actuator arranged for lifting the tiltable platform at a second platform side which is opposite to a first platform side, such that the tiltable platform is tilted towards the first platform side.

A method and apparatus for reducing a positive pressure of an actuating cylinder of a universal hinged support. An application object is the actuating cylinder of the universal hinged support. The apparatus comprises a foundation, a base frame, a force application apparatus, a direction adaptation apparatus, a universal swing rod apparatus, and an integral external connection apparatus. The method comprises: step 1, determining main design parameters and the type of the force application apparatus; step 2, structural design of the apparatus: designing the structure of the apparatus after the main design parameters and the type of the force application apparatus are determined; and step 3, calculating, testing, and evaluating an actual gravity moment or positive pressure and an effect of weight compensation, determining whether to meet design requirements, and calculating or testing the evaluated gravity moment and a reduction ratio.

An upstart motorcycle jack system that lifts a motorcycle from laying on its side to an upright position includes a scissor jack, a foot, a fulcrum pin, a mounting adaptor, and a motorcycle lift bracket. The motorcycle lift bracket is integrated onto the motorcycle. The foot is hingedly connected to a base pad of the scissor jack. The scissor jack pivotably mounts to the motorcycle lift bracket through the mounting adaptor and the fulcrum pin to initiate the lifting process. The mechanical leverage for the lifting process is provided by the scissor jack to lift the dead weight of the motorcycle pass a 45-degree angle. The scissor jack also transfers some of the motorcycle weight to the foot when the base pad starts to tilt toward the motorcycle. Once the scissor jack is fully extended, a rider can easily push the motorcycle back into the upright position.

The present invention relates to the field of engineering mechanics and more particularly, relates to an engineering work vehicle, and most particularly, relates to a vehicle with a low gravity center and aerial work platform. The vehicle includes a vehicle frame, a power system, a fuel tank, and a hydraulic tank all of which are mounted at a side of the frame. Correspondingly, the embodiment of the invention also provides an aerial work platform which provides better off-road performance and grade-ability, can work in complicated environment, and owns a longer horizontal reach and larger working range. Moreover, maintenance and repair cost is decreased, lifetime is extended, integrity is higher and appearance looks better.
