SAFETY DESCRIPTION Danger zones

OPERATOR POSITIONING When the operating machine is working, the operator must pay particular attention to his own position in other to avoid possible danger to himself and persons nearby. The area adjacent to the attachment is divided into two areas: OPERATOR AREAS These are areas in which the operator must work during normal operation of the attachment. The “operator areas” are to be considered potentially dangerous areas. In these areas, which are indicated on the following drawing, the operator should pay the maximum attention while working to protect the well-being of persons near to him; it is extremely important to follow all the accident prevention rules described to this point.

DANGER ZONES These are the areas that unauthorized personnel must not approach during work.

ATTACHMENT DESCRIPTION DESCRIPTION Attachment description

1. ATTACHMENT DESCRIPTION The Rotating Pulverizer FR Series permit the operator to perform the phases of primary and secondary demolition with a single attachment. Clamp function for primary intervention thanks to continuous hydraulic rotation that reduces movements to a minimum by working with precision. Crusher function for secondary demolition thanks to the typical jaws of a standard crusher and two interchangeable blades arranged for shearing the iron bar in the concrete. The possibility of executing the two distinct phases of demolition with a single attachment provides the economic advantage of using a single operating machine and significantly reducing the execution times for demolition work.

The closing power is produced by the thrust of a hydraulic cylinder to allow the demolition of the most resistant materials.

The load-bearing structure and claw jaws are made of anti-wear steel with a high elastic limit. This confers great anti-abrasion characteristics together with exceptional mechanical strength.

The hinges are made of thermally-treated alloy steel and rotate on hardened and ground bushings with grooves for internal lubrication. The dust abatement system with which they are equipped extends the life of surfaces in contact.

The system of interchangeable teeth used on various models of CASE CONSTRUCTION demolition equipment allows their rapid replacement directly on the job site, thus avoiding having to apply fill to worn parts, reducing maintenance costs and limiting the effects of machine downtime.

LUBRICATION The frequency of lubrication must be determined as a function of the operating conditions. The attachment must be lubricated before or after a long period of inactivity. This is especially true for the winter break. Take care that no detergent penetrates the rolling system or damages the gasket seals.

ROTATION THRUST BLOCK LUBRICATION Once the attachment is mounted on the operating machine, lubricate the rolling system and the teeth (Fig. 6.4.1). For this operation and all subsequent lubrication, only use lubricants that are acid-free, contain resins, are not hygroscopic, resist aging and with a temperature range suitable for the use of the bearing as in the table shown below (Table 6.4.2). The purpose of the complete greasing is to reduce friction, create a seal and protect against corrosion. We recommend that you grease in such a way that grease comes out of the labyrinths of the bearing or seal gaskets. There are synthetic spacers between the revolving bodies in the rolling tracks: the use of aggressive products changes the properties of the grease, corrodes the rolling tracks and damages the spacers.

 

ATTENTION! More frequent lubrication is recommended in tropical environments and in places that are damp, dusty, impregnated with impurities and subject to sharp jumps in temperature.

IMPORTANT! At the end of use under water, disassemble the hinges and carefully clean the pins and bushings to eliminate any trace of oxidation before lubricating again.

Removing the cutting edges of the attachment requires turning off the operating machine and wearing adequate IPDs (gloves, goggles and suitable clothing).

   

Remove the screws fixing the cutting edges of the attachment.

Remove the cutting edge from its seat (Fig. 6.5.1).

If the cutting edge is locked in its seat, insert a conical pin with a hammer until the cutting edge loosens.

Remove the worn cutting edge.

Insert the new cutting edge and tighten with new screws.

MAINTENANCE



DANGER! The cutting edges can fall our of their seat; make sure that all persons stay at a safe distance and that there is no property damage or personal injury if that should happen.

If correct maintenance is performed on the cutting edges, the play between them remains constant for their entire length.

CONTROL AND REPLACEMENT OF THE INTERCHANGEABLE TEETH The use of bolted interchangeable teeth for the Series FR attachment is dictated by the need to replace the points that are inevitably worn during demolition directly on the job site, thus avoiding having to recover the worn points in the workshop.

If the screws and bolts are loosened or damaged, tighten them with a wrench or completely replace them.



DANGER! Removing the interchangeable teeth of the attachment requires turning off the operating machine and wearing adequate IPDs (gloves, goggles and suitable clothing).

Replace the interchangeable teeth on the frame of the attachment (Fig. 6.5.2)   

Remove the fixing screws and relative bolts from the teeth mounted on the fixed part of the attachment.

Remove the worn teeth from their seat.

Insert new interchangeable teeth and tightening with new screws.

Replace the interchangeable teeth on the movable jaw of the attachment (Fig. 6.5.2) 





Proceed as in the preceding paragraph to replace the worn front teeth, (4) inserting the new screw (2) and tightening it with the corresponding bolt (5).

To replace the remaining worn teeth (3), unscrew one tooth at a time, taking care to correctly replace it with a new one before removing the next tooth, to avoid having to correct the “fixed bent” (6) inside the jaw.

If the above operation is not possible, open the cover on the jaw and reposition the “fixed bent” (6) to be able to insert new interchangeable teeth to tighten with new screws (1).

Fig. 6.5.2

The attachment was designed to reduce extraordinary maintenance to a minimum and it is up to the operator to determine its state and suitability for use.

We recommend stopping the attachment and performing maintenance whenever its performance is not optimal; this will allow always achieving maximum efficiency.

ANTI-WEAR MATERIAL It is periodically necessary to check the state of deterioration of the jaws of the attachment and replace the anti-wear material when necessary. The material must be applied following the instructions below.

 

ATTENTION! Before replacing the material, carefully remove any paint residues to avoid releasing toxic vapors. Also remove any deposits of cement, concrete and accumulated crushing waste on the part to be filled.

ATTENTION! Before adding welded material, make sure there is no oil or inflammable liquids near the work area.

To add welding material, connect the ground pole of the welding machine to the part to be welded, as close as possible to the welding area. The ground pole must be connected so that the current does not cross the hinges or the hydraulic cylinder. If the attachment is mounted on the operating machine during welding, follow the instructions in the latter's Manual to avoid damaging its battery or electronics. 

After carefully cleaning the area where material is to be added and the surrounding area, pre-heat to 150°C to 200 °C, checking the temperature frequently. Exceeding these temperatures can alter the mechanical properties of the material.



Do not deposit more than two superimposed layers on the claws of the attachment or on the part to be filled. If the wear on the part in question is of significant size, insert shaped and beveled material to bring the part involved to its original dimensions. Then, proceed with welding the piece and filling it.



Grind the ends of the fill material beads.



Perform a slow cooling in the absence of air drafts.



Scrupulously follow the technical application standards recommended by the manufacturer of the fill wire.

To add material use 57 HRC (600 Brinell) fill wire, Ø 1.2 mm K 300.

The recommended wires are: UTP: A67S Ø 1.2 mm FORTARGEN: A7111 MIG Ø 1.2 mm

MAINTENANCE



DANGER! Before adding material, it is necessary to turn off the operating machine and wear suitable IPDs (gloves, goggles, safety shoes and suitable clothing).
