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.

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.
