Benefits of technology

[0023]The advantage of this invention in relation to the present state of the technology used in pipe laying (track mounted) is that, since the excavator has a body with a boom capable of rotating around the lower body by means of a vertical shaft, it greatly facilitates all loading and unloading operations given that they can be carried out irrespective of the location of the machine (it can rotate 360 degrees). This feature is what makes this machine stand out from the pipe layers based on tractors with caterpillar tracks which, in order to change the position of the boom, have to turn the enti

Embodiment Construction

[0032]FIG. 1 shows (in dotted lines) an excavator equipped with the proposed accessory ready to operate in the pipe-laying mode. The jib, the bucket or work tool and the system for activating the bucket movement have all been removed. The upper body (2) is turned at an angle of 90 degrees to the lower body (1). Likewise, the counterweight (4), the operator's cabin (5), the excavating arm cylinder (11), the boom (6), the pin (15) that connects both the jib and the accessory (3) used in the pipe-laying mode to the top of the boom (6) are all visible.

[0033]The accessory (continuous lines) consists of a frame, a winch (30), the sheave (18) and a sheave with a lifting hook (38).

[0034]FIG. 2 shows in greater detail (in dotted lines) the top of the excavator boom (6) in pipe-laying or crane mode, the jib hydraulic cylinder (11) and the hydraulic fluid supply and return lines (32) of the bucket operating cylinder. Likewise, the rapid couplings (33) for connecting the hydraulic fluid flexibl...

Abstract

Accessory for providing an excavator with a dual function in earth-moving tasks: digging and refilling trenches, and as a crane (hoisting capability), to be used with advantage in the construction of pipelines. The accessory includes a frame, sheaves and a winch with hydraulic action, installable on top of the boom of a hydraulic excavator without involving modifications to the original machine, thereby providing the excavator with hoisting capability.

Description

RELATED APPLICATIONS / PRIORITY BENEFIT CLAIM[0001]The present application claims priority to Bolivian patent application SP 0127-08 filed Apr. 18, 2008 in the Bolivian Patent Office (SENAPI—Servicio Nacional De Propriedad Intelectual—Bolivia), by the same inventors (Delius and Aeschbacher), the entirety of which Bolivian patent application is incorporated herein by reference.FIELD OF THE INVENTION[0002]The invention is in the field of accessories for providing an excavator with a dual function in earth-moving tasks: digging and refilling trenches, and as a crane (hoisting capability), to be used with advantage in the construction of pipelines.BACKGROUND OF THE INVENTION AND DESCRIPTION OF RELATED ART[0003]In a construction work with mechanical facilities, such as pipe laying, particularly in the petroleum and gas industry, pipes are required for transporting fluids (hydrocarbons and water).[0004]In the construction of pipelines, two types of machines are required: excavators and pipe...
