      • • Ropes and rugs must be in good condition.
    • Requirements on the Carrier
      • • Carrier weight: The excavator may fall over if the capacity is not good enough to use the attachment or if it is equipped with a long boom and/or a long reach arm. Proper excavator should be decided for use with the attachment or such long boom a…
      • • Hydraulic system: The hydraulic system of the carrier must be suitable for the attachment. Low flow rate and pressure results in slow working speed and low crushing force respectively. Check the specification of the carrier.
    • Installation of Hydraulic Piping on the Carrier
      • Basic Circuit for Rotating Crusher Piping
        • • Relief valves to set the maximum pressure in jaw opening and closing operation.
        • • Relief valves to set the max. pressure in rotation operation (but, it is not necessary if output flow of the rotation circuit is smaller than maximum flow rate for rotation. Refer to chapter, “Technical Specifications”)
        • • The circuit to prevent cavitation in the rotation line when rotation motor stops (The hydraulic motor may be damaged if this circuit is not installed)
        • • Stop-valves in the connection with the hose from the rotating crusher.
        • • The circuit to release the residual pressure in the rotation motor when rotation motor stops. (If the rotating crusher has a slewing brake.)
    • Mounting the Rotating Crusher
      • • Attach the mounting adapter to the base plate using bolts, spring washers and nuts. We recommend you to double the nut, and never neglect to use the spring washer.
      • • In case both pin holes of the mounting adapter are not on the same level, operating direction should be considered to decide on pin hole for each arm and link arm of the carrier. If main operation is upward, the carrier’s arm needs to be connecte…
      • • Check the direction of hose connecting port. Piping line on the carrier should be in the same direction as the ports of the rotating crusher. The followings are the directions of hose connecting port of the rotating crusher.(Figure 3)
      • • Before mounting the rotating crusher, please put it on the flat place to take care of the direction of the mounting adapter as the drawing.
      • • Set the carrier’s engine speed to low idle, and move the stick of carrier slowly until its hole is aligned with that in the mounting adapter. Insert the mounting pin and assemble the stopper and its fasteners. According to mounting adapter, the s…
      • • Move the shovel cylinder and align the hole of carrier link with that in the mounting adapter in the same way as the Step 2.
      • • Remove the end caps from the connection ports on the rotating crusher and the stop valves on piping line, then connect the main port and rotation port each other with proper hydraulic hoses.
      • • The connecting threads must be undamaged and clean from sands, water, etc.
      • • Open the stop valves on piping line.
    • Adjustment of the Rotation Device
      • • Port for pressure check is positioned in both ports ‘RA’ and ‘RB’. Place a pressure gauge into either port, and set the minimum pressure unscrewing the pressure relief valve to the end. The pressure gauge must be for 400 bar or more.
      • • Place the rotating crusher to the ground or the other strong structure so that the rotating crusher can not rotate.
      • • Increase pressure by screwing the screw adjuster until the pointer of the pressure gauge reaches the recommended pressure with the rotation actuator of the carrier switched on.
      • • Pay attention to the max pressure since motor life will be reduced if it is used over maximum pressure.
      • • Position the rotating crusher for rotation, and rotate it.
      • • Set the rotation speed by adjusting the flow control valve in the carrier’s rotation pipe.
      • • The proper rotation speed is 7 ~ 12 rpm and it must not exceed 15 rpm.
  • Operation
    • Preparation for Safe and Correct Operation
      • • Mechanical connection between the rotating crusher and the carrier
      • • Locking status of the mounting pins

      • • Use only DEVELON genuine fixing bolts and lock-washers. Ensure that they are tightened correctly to the prescribed tightening torque.
      • • If the condition of the bolts and lock-washers is not good, always use new bolts and lock-washers when fitting new cutter blades.
      • • Make sure there is no particle at the contact surface between the jaw and blades. Cutter blades must contact the jaw completely.
