In another embodiment, such as shown in Figure 5, the bun-dle is arranged in a three-dimensional shape on the sup-port frame 4. The three-dimensional shape may facilitate the connection work of the bundle. The bundle 1 can be kept in said three-dimensional shape by holder(s) 18 ar-ranged on the support frame 4. The holder 18 may have a simple shape, such as a prismatic shape, that just lifts a part of the bundle up. However, the holder 18 may be shaped to shape the bundle in very precise manner. It is to be noted, that the support frame 4 may have three-dimensional surface arranged to shape the bundle.
Figure 6a illustrates a method for replacing a hydraulic harness of a working machine, and Figure 6b is a schematic side view of a step of the method illustrated in Figure 6a.
The work machine W (shown by dashed line) may be any type of a utility vehicle, such as a tractor, a truck, a farm-ing machine, a forestry machine etc. According to an as-pect of the invention, the work machine is a mine machine or a construction machine. In mines - such as underground mines and surface mines - and at other work sites differ-
11 ent type of work machines are used. The work machine is provided with one or more working device(s). For instance, the mine machine may be provided with working device(s) for executing mine work task at a work site. The mine ma-chine or a construction machine may be e.g. a rock drill-ing rig, a development drill, a tunneling drilling ma-chine, a surface drilling machine, a bolting or reinforc-ing vehicle, a rock removal machine, a longhole drill rig, an explosive charging machine, a loader, a transport vehi-cle, a loading or hauling machine, setting vehicles of gallery arcs or nets, a concrete spraying machine, a crusher or a measuring vehicle.
According to an aspect, the method for replacing a hydrau-lic harness of a working machine comprises moving 601 the kit 100 described in this description in close proximity of a work machine W. In an embodiment, all the kit 100 is moved at once, i.e. all the bundles 1 being arranged in a carrier 6. This is an effective way to realize the move-ment, but quite a lot of space around the work machine is demanded. In another embodiment, the kit 100 is moved one support frame at a time. This makes it possible to do the replacing work in very narrow or constricted space, e.g.
in a narrow mine gallery.
The method further comprises arranging 602 the support frame 4 with the bundle 1 attached thereto such that the connectors 3 stand close to the corresponding counter-connector 11 of the work machine W, and if the bundle corn-prise the at least one clamp, so that the clamp(s) stand(s) close to the corresponding clamp site 12 in the work machine. This arranging step 602 may comprise turning of the support frame from a horizontal position to a more vertical position. Then, the connectors 3 are attached 603 to said corresponding counter-connectors 11, and the at-taching means 5 arranged to attach the bundle in the sup-

Then, the connectors 3 are attached 603 to said corresponding counter-connectors 11, and the at-taching means 5 arranged to attach the bundle in the sup-
12 port frame 4 are released 605 in suitable stages of the method, between or after said attaching 603 of the con-nectors.
In an embodiment of the method, wherein the kit comprises at least one clamp 8, the at least one clamp is attached 604 to the corresponding clamp site 12 of the work machine in suitable stages of the method, before, between or after said attaching 603 of the connectors.
EXAMPLE
In a hose harness replacement work, it was replaced har-ness in a boom of a large mine drilling machine. The kit and method described in this description reduced the work time by about 80 % compared to a previous method not using the kit.
The invention is not limited solely to the embodiments de-scribed above, but instead many variations are possible within the scope of the inventive concept defined by the claims below. Within the scope of the inventive concept the attributes of different embodiments and applications can be used in conjunction with or replace the attributes of another embodiment or application.
