Method and arrangement for transferring a heavy work machine on a sloping base
First Claim
1. Method for slowing transfer of a heavy work machine on a sloping base using a separate transportation device equipped with wheels, the heavy work machine including a body, a crawler chassis fitted beneath the body, a set of booms having at least one operating cylinder, a first end and a second end, said set of booms being pivoted at the first end to the heavy work machine and a selected auxiliary device is pivoted at the second end, and a brake connected to the auxiliary device, the brake including a brake surface, the method comprising the steps of:
- towing the heavy work machine using a transfer vehicle with the aid of the transportation device,supporting the crawler chassis of the heavy work machine at least partly on top of the transportation device such that the crawler chassis is raised off the sloping base, and supporting the auxiliary device of the heavy work machine on the brake, the brake surface of the brake contacting the sloping base,using said operating cylinder of the set of booms to press the brake surface against the sloping base to create friction to slow transfer speed of the transportation device on the sloping base, andadjusting the pressing of the brake surface taking place through the auxiliary device using the operating cylinder of the set of booms.

Abstract
A method for slowing transfer of a heavy work machine on a sloping base using a separate transportation device equipped with wheels, the work machine including a set of booms having at least one operating cylinder, an auxiliary device, and a brake including a brake surface, the method including the steps of towing the work machine using a transfer vehicle and the transportation device, supporting the work machine at least partly on top of the transportation device such that the crawler chassis is raised off the sloping base, and supporting the auxiliary device on the brake, the brake surface of the brake contacting the sloping base, using the operating cylinder to press the brake surface against the sloping base to create friction to slow transfer speed of the transportation device, and adjusting pressing of the brake surface taking place through the auxiliary device using the operating cylinder.

12. Arrangement for transferring a heavy work machine on a sloping base, the heavy work machine including a body, a crawler chassis fitted under the body, and a set of booms having at least one operating cylinder, a first end and a second end, said set of booms being pivoted at the first end to the heavy work machine and a selected auxiliary device pivoted at the second end of said set of booms, the arrangement comprising:
-
a separate transportation device equipped with wheels, on top of which transportation device the crawler chassis of the heavy work machine is arranged to be at least partly supported for a duration of transfer such that the crawler chassis is raised off the sloping base, a transfer vehicle for towing the heavy work machine during the transfer, the crawler chassis of the heavy work machine being at least partly supported on top of the transportation device, a brake including a brake surface connected to the auxiliary device at a distance from the body for retarding the transfer speed of the heavy work machine with the aid of friction and arranged to be pressed against the sloping base by using said operating cylinder of the set of booms with the aid of the auxiliary device to brake the transfer speed of the heavy work machine during the transfer with the aid of friction, and an operating device for using the operating cylinder to press the brake surface of the auxiliary device against the sloping base. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
