摘要:
A towing arrangement for a mobile work machine, and a mobile work machine. The arrangement (100) comprises a towing element (1) for allowing a towing tool to be connected to the towing arrangement (100). The towing element (1) is arranged to move in relation to the frame (2) of the work machine when a towing force is affecting to the towing element (1). The arrangement (100) further comprises a hydraulic actuator (3), a first part (4a) of the hydraulic actuator (3) attached to the frame (2), and a second part (4b) of the hydraulic actuator (3) connected to the towing element (1), such that the hydraulic actuator (3) is arranged to create hydraulic pressure along with movement of the towing element (1) in relation to the frame (2). The towing arrangement (100) comprises a flexible connection element (5) that is arranged to connect the towing element (1) to the hydraulic actuator (3) for transmitting said movement of the towing element (1) to the hydraulic actuator (3).

The present invention relates to a method for driving a mining and/or construction machine, where said machine is arranged to be controlled by an operator by means of maneuvering means, where said operator, when driving said machine, provides steering commands by means of said maneuvering means for maneuvering said machine. The method comprises, when said machine is being driven in an environment having at least a first obstacle—estimating a path that, has been requested by said operator by means of said steering commands,—by means of a control system determining whether said machine when moving according to said requested path will be driven within a first distance from said first obstacle, and—when said machine, when travelling along said path, will be driven within a first distance from said first obstacle, influencing the path of said machine by means of said control system.

The invention relates to a method for slowing transfer of a heavy work machine on a sloping base, in which the work machine (10) includes a body (13), a crawler chassis (11) fitted beneath the body (13), and a set of booms (20) pivoted at its one end (17) to the work machine (10), at the other end of which is a selected auxiliary device (55), and a transportation device (12) is equipped with wheels (15), in which method the work machine (10) is transferred by supporting the work machine (10) on the crawler chassis (11) at least partly on top of the transportation device (12), and towing the work machine (10) using the transfer vehicle (14) with the aid of the transportation device (12) and using friction to slow the transfer speed of the transportation device (12) on the sloping base. In the method the brake surface (22) is pressed against the base (16) by means of the auxiliary device (55) in order to retard the transfer speed and the pressing of the brake surface (22) taking place through the auxiliary device (55) is adjusted using the set of booms (20). The invention also relates to an arrangement in connection with a heavy work machine for transferring the work machine on a sloping base.

摘要:
In combination a loader unit and haul unit for use in a block caving mining operation. Each of the loader unit and the haul unit comprise a removable bucket, which can be used for loading ore. In use the bucket carrying a load of ore can be transferred from the loader unit to the haul unit so that the haul unit can transport the ore from a loading site to a crusher. The loader unit and haul unit have a respective longitudinal axis extending from the fore end to the aft thereof, and the bucket is elongate with a longitudinal axis. In use when the bucket is mounted to the loader unit the longitudinal axis of the bucket is disposed orthogonally to the longitudinal axis of the loader unit. When the bucket is transferred to the haul unit, the bucket is placed upright on the haul unit with the longitudinal axis of the bucket parallel to the longitudinal axis of the haul unit.
