Problems solved by technology

The problem encountered especially in crushing tubing is that with the jaws in their fully open position, the openings of the jaws are able to successfully grasp the tubing, but the initial cutting force is insufficient so that in many In cases where the piping cannot be cut, a larger size installable device is required
In addition, this type of mountable device has the disadvantage that the speed of opening and closing of the articulated jaws is low due to the large return volume between the surface of the pressure piston and the surface of the piston rod of the hydraulic cylinder
This causes increased cycle times for cutting operations

Embodiment Construction

[0033] Figure 1a and Figure 1b A mountable device 11 known from DE 600 21 539 T2 is shown. It is incorporated by reference in its entirety into this disclosure. The installable hydraulic device 11 comprises a housing 12 having an engagement interface 14 by means of which said installable hydraulic device 11 can be attached by a simple alternative to a boom not shown in further detail in the figures and attached to the hydraulic system of a loading device not shown in further detail, such as a skid loader or an excavator. The housing 12 includes a fixed lower jaw 16 or fixed lower protrusion and a hinged upper jaw 18 or hinged upper protrusion. The upper jaw 18 is pivotable about a bearing shaft 19 which is arranged in a fixed manner on the housing 12 . Alternatively, unlike the embodiment described above, the jaw 16 may be pivotable about said bearing shaft 19 like the upper jaw 18 .

[0034] Both the upper and lower jaws 18 , 16 are provided with a cutting tool 20 . Th...

Abstract

The invention relates to a method of activating a mountable hydraulic appliance, and to such mountable hydraulic appliance for the shearing or crushing of structures, in particular for demolition, communication or recycling, said appliance having an upper jaw and a lower jaw at least one of which is pivotally hinged on a bearing axis arranged on the housing, the hinged jaw being activated by a first hydraulic cylinder and by at least one further hydraulic cylinder acting thereon so as to be moved from an open position to a cutting position and / or a closed position and vice versa, the hydraulic cylinders which act upon the hinged jaw being either pressurised simultaneously, or the initiation of a closing movement of the at least one hinged jaw from an open position being such that initially only one hydraulic cylinder is pressurised and, as the required compression force increases during the closing movement, the at least one further hydraulic cylinder is equally pressurised.

Description

technical field [0001] The present invention relates to a method of initiating the opening and closing movements of installable hydraulic equipment for shearing and crushing of structures, and an installable hydraulic equipment, in particular for demolition, crushing or Recirculating hydraulic equipment. Background technique [0002] DE 600 21 539 T2 discloses a class of mountable devices which can be joined to a boom and to the hydraulic system of a loading device such as a skid loader or an excavator. To this end, a joint interface is provided on the housing of the mountable device, on the one hand for attaching the housing of the mountable device to the boom, in particular in an exchangeable manner, and on the other hand for attaching the load The hydraulic system of the equipment is connected with the hydraulic pipeline, that is, the supply line and the return line of the installation equipment. The housing is provided with fixed lower jaws or fixed lower projections a...
