Abstract
A cab for earth-moving machines is constituted by a support structure within which a control station for an operator is obtained. A hinging element and a locking element permit the fastening of the support structure to a frame of an earth-moving machine. Control levers are positioned within the support structure in correspondence with the control station for controlling operative organs of the earth-moving machine. A plurality of hydraulic conduits are connected to the control levers and a plurality of semi-couplings are connected to at least a portion of the plurality of hydraulic conduits and are able to be coupled to a corresponding plurality of semi-couplings connected to a hydraulic system of the earth-moving machine.

A modular cab for earth-moving machines comprising:
- a support structure, having a bottom portion, side walls, and a roof, and defining inside a control station for an operator comprising a seat for the operator mounted on said bottom portion, said bottom portion also defining a floor of the cab;
- fastening means on the cab for selectively fastening to and removing the cab from a frame of an earth-moving machine;
- control means mounted within said support structure and operable by an operator on said seat for controlling operative organs of the earth-moving machine;
- and
- connecting means on the cab for operatively connecting said control means to said operative organs of the earth-moving machine including a plurality of hydraulics conduits connected to said control means, a plurality of semi-couplings connected to at least a part of said plurality of hydraulic conduits and able to be coupled to a corresponding plurality of semi-couplings connected to a hydraulic system of the earth-moving machine, to allow the activation of said machine by means of said control means, and at least an electrical circuit operatively connected to said control means and having at least a terminal fixed to the cab connectable to a corresponding terminal of an electrical circuit of the earth-moving machine to connect said electrical circuit of the cab to said electrical circuit of the machine;
- wherein the connecting means together with the fastening means permit a testing of the modular cab to verify functionality of the control means and seals of a hydraulic system thereof apart from the earth-moving machine.
