The present disclosure relates to a welding base metal for recycling a railway wheel and a method for recycling a railway wheel using the same, which can overlay-weld a railway wheel with a welding base metal suitable for overlay-welding a railway wheel through a heat treatment, form a surface hardened layer, and strengthen the metal structure of the railway wheel, in order to recycle the railway wheel.

The welding base metal for recycling a railway wheel may be used as a surface hardened layer of a railway wheel because the welding base metal has high hardness while exhibiting a similar property to the railway wheel. Furthermore, the welding base metal can change the metal structure of the recycled railway wheel, and thus delay the initial wear time of the recycled railway wheel. The method for recycling a railway wheel may overlay-weld the damaged railway wheel to its original size, form a surface hardened layer, and change the metal structure of the railway wheel by changing the composition of the welding base metal and performing the pre-heat treatment and the post heat treatment, thereby minimizing the occurrence of damage to the recycled railway wheel.

The rail vehicle has a guide device configured to guide traveling of a bogie on a traveling track by rolling guide wheels in a state of bringing the guide wheels into contact with guide rails installed on both sides of the traveling track in a vehicle width direction perpendicular to a traveling direction, wherein: the guide device has an arm and the guide wheels, the arm having a central portion fixed to a stationary member, extending to both sides in the vehicle width direction, and having both end portions elastically deformable in a direction in which the guide rails extend, the guide wheels being mounted on the arm at the both end portions of the arm in the vehicle width direction; and a center of each of the guide wheels is displaced from a center line of the arm, the center line extending in the vehicle width direction.

A system for reprofiling a wheel set of a railway vehicle allows the center of rotation of the wheel set to move relative to supporting rollers. A cutting tool used to reprofile the wheel profile on a wheel set is moved relative to the center of rotation of the wheel set to maintain a constant distance between the center of rotation and the cutter. The system avoids mechanically forcing a constant location of the wheel set relative to the center of rotation.

A dual mode vehicle that operates on guided rails and roadways includes a capsule, a carriage, a front left drive system, a front right drive system, a rear left drive system, a rear right drive system, a pod control unit, and at least one battery. The carriage includes a spherical frame-housing and a base. A spherical cabin of the capsule is attitudinally mounted within the spherical frame-housing. The front left drive system, the front right drive system, the rear left drive system, and the rear right drive system each includes a motor, a drive axle, a road wheel, and a rail wheel. The road wheel and the rail wheel are axially mounted to the drive axle. The motor that is mounted to the base is operatively coupled with the drive axle through the at least one battery and the pod control unit to operate a roadway or railway transportation mode.

Embodiments relate to a cart assembly having a lower deck, an upper deck, and a gantry. The lower deck has designated areas for empty containers and for filled containers. The gantry includes a gripper system configured to grab at least one container from the empty-container staging area and transport it to a receiving site, where a crop harvesting apparatus deposits a crop in the container. Once the container is filled, the gantry moves the filled container so as to position it within a filled-container staging area of the lower deck. The gripper system then releases the container. The process is continued while the cart assembly is transported throughout a crop harvesting facility to harvest crops.

A noise-absorbing device for a railway vehicle wheel includes: at least one strip extending radially from a connecting end capable of being fastened to the periphery of the wheel, to a free end; and at least one damping mass fastened on a face of the free end of the strip, away from the connecting end. The strip includes at least two metal or composite layers and at least one layer of viscoelastic material gripped between the two or composite metal layers.

The wheel is for a railway vehicle that travels on a rail. The wheel includes a wheel tread, a flange and a throat portion. The wheel tread is provided at an outer circumferential portion of the wheel. The wheel tread faces a head surface of the rail. The flange is provided at the outer circumferential portion of the wheel. The flange projects further outward than the wheel tread in the radial direction of the wheel. The throat portion connects the surface of the flange and the wheel tread. The throat portion has a protrusion. The protrusion projects to the rail side. The protrusion extends along the entire circumference of the throat portion.
