Abstract

A method for moving a processing device, a frame of a processing device and a processing device, which is moved on a base. The processing device comprises at least one processing unit and a frame, to which the processing unit is attached, as well as at least four legs articulated to the frame. The legs comprise support plates settable against the base. The legs are settable into a support phase, where the support plate settles against the base and into a transfer phase, where the support plate is off the base. The processing device is moved without lowering the frame onto the base so that the legs are controlled to settle to the support phase and the transfer phase alternately so that at least three legs are in the support phase when the processing device moves.

determining the position of the support plate in relation to the frame on the basis of the measurements.

38. The method according to claim 32, wherein the method further comprises:

monitoring the contact of the leg with the base by means of determining the pressure caused by the support plate against the base.

39. The method according to claim 35, wherein, for defining the control signals, at least one of the following parameters is used:

the position of the support plate in relation to the frame,

the pressure caused by the support plate against the base,

42. The method according to claim 32, wherein the method further comprises:

rotating, by means of the legs, the processing device around a freely selectable point.

43. The method according to claim 32, wherein the leg further comprises:

a hydraulic cylinder for adjusting the length of the leg; and

a pressure sensor for measuring the pressure prevailing in the hydraulic cylinder;

wherein the method further comprises;

determining, on the basis of the pressure in the hydraulic cylinter, the pressure caused by the support plate against the base.

44. A processing device, comprising:

a frame;

at least one processing unit for processing mineral material, wherein the processing unit is attached to the frame;

at least four legs articulated to the frame for moving the processing device without lowering the frame onto a base, e.g. the ground, wherein each leg comprises a support plate settable against the base, and wherein each leg is settable into a support phase and a transfer phase, in which support phase the support plate sets against the base and in which transfer phase the support plate is off the base; and
