The invention provides in some aspects a transport system comprising a guideway with a plurality of propulsion coils disposed along a region in which one or more vehicles are to be propelled. One or more vehicles are disposed on the guideway, each including a magnetic flux source. The guideway has one or more running surfaces that support the vehicles and along which they roll or slide. Each vehicle can have a septum portion of narrowed cross-section that is coupled to one or more body portions of the vehicle. The guideway includes a diverge region that has a flipper and an extension of the running surface at a vertex of the diverge. The flipper initiates switching of vehicle direction at a diverge by exerting a laterally directed force thereon.

Aspects of the invention provide a transport system powered by short block Linear Synchronous Motors (LSMs). The use of short blocks allows vehicles to move under precise control even when they are in close proximity to each other. The design allows the vehicles to be propelled and guided while negotiating sharp turns and negotiating merge and diverge switches. A coreless LSM can be used to create propulsive force without attractive force so as to allow a relatively high drag vehicle suspension, such as a vehicle sliding on a smooth surface. Further aspects of the invention provide a switching member that is selectively moveable relative to a guideway in order to change a magnetic force acting on the vehicle transverse to a direction of motion of the vehicle.

A system for switching a transport vehicle comprising: a guideway, a vehicle that moves along the guideway, and a magnetic field source that creates a force on the vehicle to affect motion in a desired direction at a switch. Once the vehicle has started motion through the switch the guidance can be continued by use of permanent magnets until the normal guidance system is effective. The switching scheme can work with any suspension scheme, including wheels and maglev, and can work with any lateral guidance scheme, including horizontal guide wheels and magnetic guidance. The system can be used with very closely spaced vehicles, such as with Personal Rapid Transit, material handling, and elevators with multiple cabs in the same shaft.

A robot moving includes a robot body, the driving wheel, a motor to drive the driving wheel by rotating the rotation axis, a connecting arm to connect and support the driving wheel and the robot body.

The invention belongs to the field of rail traffic and relates to a U-shaped rail double-safety running and levitation driving energy-saving mechanism which is suitable for low-medium-speed maglev train double-safety running and levitation driving energy saving. The mechanism is composed of a U-shaped rail 1, a self-locking hydraulic traveling wheel mechanism 2, a connecting frame 3, a train body 4, an air spring 5, a bogie arm 6, a spindle 7, an aluminum sensing plate 8 and levitation magnets 9. By designing a U-shaped rail structure, production efficiency of the U-shaped rail is improved, roller consumption in hot rolling production is reduced, and production cost is lowered. By combining the U-shaped rail structure with the self-locking hydraulic traveling wheel mechanism, a maglev train is enabled to have a magnetic levitation and rubber wheel double-safety running mechanism, levitation-starting energy consumption of the maglev train is reduced remarkably, traction levitation energy consumption is reduced by 10-15%, and energy-saving effect is obvious. Running safety and accident emergency response capability are improved remarkably, and when a full-levitation system is in a failure, driven by a linear motor, a rubber wheel supporting train still can safely get to a target station.

A system and method for automated handling, transferring and storing conventional cargo storage containers on a cargo ship wherein the containers are stored in a multi-tier cell system and are manipulated by powered transfer units which are selectively moveable along an intersecting overhead track system such that containers may be simultaneously retrieved from, moved or placed within any of the cells of the ship. The transfer units are equipped both with hoists, which control spreader beams which are selectively secured to the cargo containers, and guide stabilizers, which prevent undesirable movement of the cargo containers when they are elevated above the cell structures such that the containers may be manipulated even during rough sea conditions such that the system is essentially continuously operable as a floating supply distribution system.

An improved zip line trolley allowing a rider control of his or her speed while traversing along a suspended cable (8) as seen in FIGS. 1A and 1B. The trolley comprises front and rear pulleys (44F) and (44R) conjoined via pulley housing (16) with left and right horizontal handles (10L) and (10R) attached to vertical shaft (12). Front and rear hand brake levers (20F) and (20R) are mounted onto left and right horizontal handles (10L) and (10R). When front and rear hand brake levers (20F) and (20R) are squeezed by the rider, they create a constricting force on front left and right calipers (32FL) and (32FR) along with rear left and right calipers (32RL) and (32RR) of FIGS. 2A and 3A. Thus, friction is applied to front and rear pulleys (44F) and (44R) via front left and right brake pads (34FL) and (34FR) along with rear left and right brake pads (34RL) and (34RR). This frictional force slows the rider's speed to his or her desired rate and brings the rider to a safe stop at a precise location along suspended cable (8).

Described herein are various embodiments of trolleys usable for traversing cables such as zip lines. Various embodiments have been particularly adapted to perform better under different circumstances or in different applications using braking including impact braking.

A traveling mechanism for a lifting device, especially for a lifting device having a laterally cantilevering boom, is movable on rails with at least two running wheels.

The connection element has, at the region projecting down out of the rail, at least one running roller which is freely rotatable about a horizontal axis and rolls on a horizontal outer running surface of the rail. To effectively divert horizontal forces and uniformly distribute the vertical forces to the running wheels, running wheel axles are rigidly connected with a running wheel carrier, and the running wheel carrier and connection element are swivelably connected by a universal type joint. In addition, at least one support roller is rotatably mounted at the connection element in the interior of the rail. The support roller freely rotates about a vertical axis and rolls along at least one of the side surfaces to transmit horizontal forces to the rail.

Unstable ground is found in many situations in many locations around the world and causes such locations to be unsuitable for building without further support or stabilization. Unstable ground, such as landfills, can be used for beneficial purposes as opposed to laying dormant. A segmented ballast base support structure according to an embodiment of the present invention can be configured to support free-standing structures, such as solar power collection systems and wind turbines. The segmented ballast base support structure can be deployed at unstable ground sites without digging or expensive filling stabilization techniques. Segments of the base support structure can be precast at an offsite location and transported to a site in segments and sections. The segmented base support structure allows for a cost effective solution to digging, as well as an easier method of shipping and transporting structures that would otherwise have to be built on site.
