A track system may include a track assembly and a support assembly. A track assembly may include a toothed portion. The support assembly may include a support member removable from and adjustably connected to the track assembly. The toothed portion may include a plurality of track teeth. The support member may include an adjuster pinion. The adjuster pinion may include a plurality of pinion teeth configured to engage the plurality of track teeth. The adjuster pinion may be adjustable to an engaged position in which the adjuster pinion and the toothed portion are engaged with one another. The adjuster pinion may be adjustable to a disengaged position in which the adjuster pinion and the toothed portion are not engaged with one another.

A support member may be connectable in a removable and adjustable manner to a track assembly. The support member may include an electrical connector, a contact, and a biasing member. The electrical connector may be adjustable to a first position and a second position. The contact may be connected to the electrical connector and configured to engage a conductor of said track assembly. The contact may be engageable with said conductor when the electrical connector is in the first position. The contact may not be engageable with said conductor when the electrical connector is in the second position. The biasing member may be configured to bias the contact into engagement with said conductor when the electrical connector is in the first position.

The present invention relates to a bogie structure for a mountain railway car. The bogie structure is configured as follows: a traction motor for driving an axle of mountain railway car is installed on a car body to simplify the bogie structure and to minimized interference between the traction motor and other components constituting the bogie, and a first and a second bearing are respectively inserted and installed between a first and a second axle and a first and a second wheel, so that a first and a second wheel located in one side close to a turning center are rotated less than a first and a second wheel located in the other side opposite thereof and a traveling distance of the wheels located in the turning-centered side is generated corresponding to a length of a turning-centered side railway, whereby the mountain railway car is improved in traveling stability.

An example robotic device includes: a circumferential carriage configured to drive the robotic device along a rail configured to be mounted to a curved surface, the circumferential carriage comprising: (i) a frame base, (ii) a frame mounted to the frame base, (iii) one or more wheels coupled to the frame base and configured to engage with the rail, (iv) a worm gear arrangement, and (v) a main drive gear coupled to the worm gear arrangement and configured to engage with a rack disposed on the rail; and a transversal carriage comprising: (i) a cross slide slidably mounted to the frame, (ii) a transversal rack coupled to the cross slide, (iii) a cross slide motor mounted to the circumferential carriage, and (iv) a cross slide drive gear coupled to the cross slide motor and having gear teeth engaging with respective teeth of the transversal rack.

A method and apparatus are provided for sorting or retrieving items to/from a plurality of destinations areas. The items are loaded onto one of a plurality of independently controlled delivery vehicles. The delivery vehicles follow a track that guides the delivery vehicles to/from the destination areas, which are positioned along the track. Once at the appropriate destination area, an item is transferred between the delivery vehicle and the destination area.

A composite climb structure includes a climber, a horizontal planar structure, and a ramp coupled on to a base plate. The horizontal planar structure and the ramp are collinearly situated on opposite sides of the climber. The climber is pressed by a robotic vehicle moving on to it from the horizontal planar structure, the climber being pressed to a final position, wherein the angle of elevation (BOC) of the climber is same as the angle of elevation of the ramp, thereby facilitating traversal of the robotic vehicle from the horizontal planar structure on to the ramp.
