The present disclosure discloses an apparatus that can be retracted for efficient storage and can be used for transporting materials from one location to another. The apparatus includes a retractable assembly coupled to track members that are expanded and retracted using the retractable assembly. The retractable assembly uses a plurality of arms connected to a slide member that have slide attachment members that move along the slide to retract and expand the present invention. The apparatus can be configured to cooperate with a forklift assembly, a storage box member or platforms to transport materials and loads. The apparatus can be two or four wheel drive and can be configured with more wheel members depending on the desired use.

A tensioning system of traction tracks of a machinery by means of a hydraulic cylinder applying a tensioning force on at least one of the wheels on which the track is wound according to a closed chain configuration in which the hydraulic cylinder is fed with different pressures according to the traction direction, in a first traction direction the feeding pressure of the tensioning hydraulic cylinder being a first pressure approximately corresponding to the pressure which is generated by a pump which is present on a closed circuit feeding the traction devices, in a second traction direction the feeding pressure of the tensioning hydraulic cylinder being a second pressure corresponding to the pressure of the closed circuit up to a predetermined upper limit value.

A laser cladding mobile platform comprises a platform arranged with a laser, a powder feeder, a processing platform, an electric generator, a power distribution cabinet and a PLC control system. The laser cladding mobile platform also comprises a self-propelled mechanical arm which comprises a multivariant mechanical arm and a crawler trolley, the multivariant mechanical arm is mounted on the crawler trolley; the multivariant mechanical arm is equipped with a laser cladding head at its end, the laser inputs laser light into the laser cladding head through optical fibers, the powder feeder is connected to the laser cladding head through a powder feeding tube, the electric generator supplies power for all the devices via the power distribution cabinet, the PLC control system controls the operation of each device.

Power machines, power sources for power machines, and methods which provide a hydraulic signal from a hydraulic system, through the swivel joint or swivel, to control a tensioning cylinder coupled to the undercarriage without requiring a modification to the swivel. In exemplary embodiments, the same hydraulic signal provided to at least one other hydraulic component on the undercarriage to control another machine function is also provided to control one or more tensioning cylinders. For example, exemplary disclosed embodiments provide the same hydraulic signal to tension a tensioning cylinder as is provided to shift one or more two-speed drive motors. This prevents or reduces the likelihood of de-tracking without requiring a change or redesign of the swivel.

The present invention relates to an intermediate storage vehicle for storing milled material and also to a work train with such an intermediate storage vehicle, a surface milling machine and a transport vehicle.

A cooling package mounting assembly for a machine is provided. The cooling package mounting assembly includes a first elongated frame member and a second elongated frame member. The cooling package mounting assembly also includes a first top coupling bracket, a second top coupling bracket, a first bottom coupling bracket and a second bottom coupling bracket. The cooling package mounting assembly includes a mounting arrangement coupled to at least one of the first elongated frame member and the second elongated frame member. In a first configuration, the mounting arrangement is configured to removably support a first type of heat exchanger of the cooling package between the first elongated frame member and the second elongated frame member. In a second configuration, the mounting arrangement is configured to removably support a second type of heat exchanger of the cooling package between the first elongated frame member and the second elongated frame member.

A perception system for an autonomous machine to be hauled by a towing vehicle includes sensors that are configured to determine characteristics of an environment associated with the machine. Such characteristics associated with the machine include at least structural characteristics of the towing vehicle. The sensors are further configured to detect a presence of the towing vehicle on a job site, an orientation of the towing vehicle on the job site, and a loading end of the towing vehicle. The perception system further includes a controller that is communicably coupled to each of the sensors. The controller is configured to actuate movement of the machine in relation to the towing vehicle based on the characteristics of the environment determined by the sensors.

The reducing agent tank has a tank main body and a feed pipe. The tank main body stores a reducing agent to be supplied to an exhaust gas treatment device. The feed pipe protrudes from the tank main body. The feed pipe is provided to replenish the tank main body with the reducing agent. A support base supports a vessel for the reducing agent for replenishment of the reducing agent tank. The support base is variable in position between a developed position in which the support base is arranged at a greater distance from the tank main body than from the feed pipe in a direction of protrusion of the feed pipe from the tank main body in a plan view and a stored position in which the support base is stored in an exterior cover.
