Abstract:
The present invention provides a robot which is suitable for travel through a pipeline. The inventive robot comprises at least one tracked drive means and at least one roller means that can swivel about an axis substantially normal to a rolling axis thereof, wherein said at least one tracked drive means and at least one roller means are provided with magnetic means for generating a magnetic adhesion force between the robot and an internal wall of the pipeline.
Abstract:
The invention relates to a modular crawler-track unit for a forest machine, which crawler-track unit (14) includes - a crawler-track frame (16), a sleeve axle (77), for supporting the crawler-track frame in the forest machine, a crawler mat (18) arranged in a circulation, at least one drive wheel (20) mounted in bearings in the said crawler-track frame (16), at least one idler wheel (23) mounted in bearings in the said crawler-track frame (16), support means (25), which are arranged to conform according to the shape of the surface of the ground, in order to distribute the surface pressure of the crawler-track unit (14) evenly, and a drive shaft (60) mounted in bearings in the said crawler-track frame (16). The crawler-track unit (14) further includes - a shaft (80) mounted in bearings on the crawler-track frame (16) for pivoting the said drive wheel (20) to the crawler-track frame (16) at a distance from the drive shaft (60), and power-transmission means (41) fitted between the said shaft (80) and the drive shaft (60) for transmitting power from the drive shaft (60) to the drive wheel (20). The invention also relates to a corresponding forest machine.
Abstract:
A tracked vehicle, especially a snow scooter, that has two laterally spaced-apart front drive-track assemblies (10), each of which is turnable around a substantially vertical axis and which are coupled for common turning. Each drive-track assembly is carried by a vehicle chassis (11) via a vertically movable link device, which in respect of vertical turning rests against the chassis via a spring-damper assembly (7), and the drive-track assemblies are mechanically coupled by a parallel steering mechanism (23-26), which is manoeuvrable by a driver of the vehicle.
Abstract:
The invention concerns a surface traversing apparatus that includes a frame, a seal having a seal perimeter that is mounted to the frame, and a drive configured to move the apparatus relative to the surface. The seal perimeter is adapted substantially for rolling contact with the surface to be traversed. The device is capable of suction adhering and moving along horizontal, vertical, inverted surfaces and the like, and overcoming obstacles or surface irregularities while maintaining suction adhesion to the surface. The device can be propelled along the surface with a locomoting rolling seal assembly, which provides both a seal to affect the vacuum adhesion and the locomotion to drive the device across the surface.

Abstract:
The present invention relates to a vehicle (10) that has a frame (12), a driving track assembly (14), and a pair of secondary driving assemblies (16) mounted on opposing lateral sides of the track assembly (14). More specifically, the present invention relates to a vehicle (10) that has one or more counterbalance structures (56, 58) for offsetting longitudinally off-center loads (80, 90) carried on the frame (12) of such a vehicle (10).
