Embodiment Construction

[0032] refer to figure 1 , an embodiment of the invention includes a working machine 1, such as a backhoe loader (such as figure 1 shown) or excavator (such as figure 2 shown). The working machine 1 comprises a drive running gear 2 preferably comprising two or more pairs of wheels 3 mounted on respective axles, wherein at least one axle is coupled to a drive means which drives at least one pair of wheels 3 Rotational movement.

[0033] In the examples (see for example figure 1 ), two or more pairs of wheels 3 are arranged to engage the ground 4, and the movement of the working machine 1 causes the or each pair of wheels 3 to perform a rotational movement across the ground 4.

[0034] It should be appreciated that other driven running gear 2 can be provided, such as two or more endless crawlers (see for example figure 2 ).

[0035] In the examples (see for example figure 1 ), drive the traveling device 2 to carry the main body 5 of the machine 1, and the first working ...

Abstract

A working machine comprising: a working arm; a hitch arrangement attached to the working arm and configured to be removably secured to a working implement; one or more sensors configured to determine an orientation of a working implement secured to the hitch arrangement and to output a signal indicative of the orientation of a working implement secured to the hitch arrangement with respect to gravity; and a control module configured to receive the signal from the one or more sensors and to perform a safety function in response to receipt of the signal such that the safety function is performed if the orientation of a working implement secured to the hitch arrangement with respect to gravity is an unpermitted orientation.

Description

technical field [0001] Embodiments of the invention relate to a working machine comprising a hitch arrangement. Background technique [0002] Conventional work machines, such as backhoe loaders, used in places such as the construction industry, agriculture, mining, earthmoving, object handling, etc., include at least one working arm carrying a hitch or coupler arrangement that Or the coupling device may be an at least partially automated coupling device and configured to couple with a work implement. The hitch typically includes a hook coupled to a pin of the work implement such that the hook extends around at least a portion of the pin. The hitch typically also includes another hook configured to receive another pin of the work implement. [0003] The linkage device is detachable from the working arm and is coupleable to the working arm by an attachment device further configured to couple the work implement to the working arm. [0004] The coupling means comprise closing...
