Abstract
Performance indicating device (400) adapted to be connected to a processing apparatus (100), in particular to an apparatus for demolishing and in particular for milling surfaces or layers (Sr) upon which one can walk or drive such as for example surfaces made of asphalt or cement or of similar solid materials, and/or to a main operating machine (300) actuating said apparatus (100), said apparatus (100) comprising processing means (10), said device comprising at least a first movable indicating element (401) adapted to be alternatively moved in a first sense of motion and in the opposite sense in case of increase and decrease of the stress undergone by said processing means (10), respectively.
Claims14
Performance indicating device adapted to be connected to a processing apparatus, in particular to an apparatus for demolishing and in particular for milling surfaces or layers upon which one can walk or drive such as for example surfaces made of asphalt or cement or of similar solid materials, and/or to a main operating machine actuating said processing apparatus, said processing apparatus comprising processing means, said device comprising:
- at least a first movable indicating element adapted to be alternatively moved in a first sense of motion and in the opposite sense in case of increase and decrease of the stress undergone by said processing means, respectively,
- wherein
- said device comprises a second indicating element, and in that
- said first indicating element is connected to said second indicating element so as to drag said second indicating element during its motion in said first sense of motion, and so as to freely move with respect to said second indicating element for at least a predefined segment of its motion in the sense opposite to said first sense of motion.
A performance indicating device for use with a hydraulic machine comprising:
- a main body coupled to a hydraulic line of the hydraulic machine, said main body having an indicator end and a hydraulic line end;
- a piston placed within said main body;
- a first indicator placed on the indicator end of said main body;
- an intermediate sub portion connecting said piston and said first indicator together, whereby said piston and said first indicator move together longitudinally;
- an abutting surface placed within said main body between said piston and said first indicator;
- a spring placed between said abutting surface and said first indicator wherein said spring biases said first indicator towards said abutting surface;
- and
- a second indicator placed on said main body adjacent to said first indicator, said second indicator coupled to said first indicator so that during motion of said first indicator in one longitudinal direction said second indicator is dragged or moves with said first indicator, and during motion of said first indicator in an opposite longitudinal direction from the one longitudinal direction said first indicator is free to translate or move freely with respect to said second indicator,
- whereby upon calibration said first indicator drags said second indicator to a position indicating a maximum hydraulic pressure allowed and upon a drop in hydraulic pressure the second indicator will not move providing an operator with an indication of the maximum hydraulic pressure allowed.
