Embodiment Construction

[0097] First refer to figure 1 , shows that the excavator 10 includes an excavator arm 12 , a cab 14 , an engine area 16 , crawlers 18 and a hydraulic lever 20 for controlling the operation of the excavator arm 12 .

[0098] A quick coupler 24 is connected to the free end 22 of the excavator arm 12 . For this purpose, coupler 24 is provided with two connection points 26 (see figure 2 ), and two connection pins (not shown) extend through those connection points 26 for connection. This type of coupling system is conventional in the art and is applicable to many different forms of excavators when coupling the coupler to the free end of the arm of such excavators.

[0099] As shown, an attachment 28 in the form of a bucket is connected to the coupler 24 . As a result, the excavator 10 , via its excavator arm 12 and its hydraulic lever 20 , is available for performing excavation operations by the attachment 28 .

[0100] now refer to figure 2 , showing further details of a t...

Abstract

An excavator (10) has a quick coupler (24) coupled to the distal end (22) of its excavator arm (12). The quick coupler (24) can be operated from the cab (14) of the excavator (10), and is connected to a warning control system (48) or an instructional device (102). The warning control system (48) is connected to a coupler control circuit (46), which controls the coupler (24) and the system or circuit acquires information on the coupler's status. A control system activation warning circuit is then arranged to be responsible for issuing warning signals (53, 54) to personnel located external of the cab when the coupler control circuit (46) is activated into an accessory coupling procedure mode, or an accessory decoupling procedure mode.; To do this, the warning circuit (48) is coupled to an audio and / or visual alarm (50, 52) for directing the warnings (53, 54) to the personnel, including bystanders. The instructional device, however, instructs the operator as to how to use the coupler.

Description

technical field [0001] The invention relates to a coupler alarm device and an instruction guiding device suitable for excavator couplers. In particular, the present invention relates primarily to coupler warning devices whenever a coupling or uncoupling procedure is performed on an excavator, i.e. when a bucket or other such accessory is coupled to the excavator arm of the excavator or removed from the excavator's Said coupler alarm operates to sound an alarm when the arms are uncoupled, and secondly the present invention relates to a means for providing instructions to the user, potentially integrated with the coupler alarm. Background technique [0002] A quick coupler is typically fitted to the free end of the excavator arm of an excavator. The quick coupler facilitates automatically coupling an attachment to or decoupling an attachment from the end of an excavator arm. Quick couplers can be semi-automatic or fully automatic. Semi-automatic couplers require manual step...
