The serial number will be comprised of the following sequence of numbers and letters: 0N-0000.

  • Page 17: Hydraulic Installation

    SHUT-OFF VALVES Most NPK Hydraulic Installation Kits use two shut-off valves (k4) on the dipper stick (k1) of the carrier. These valves control the hydraulic oil going to the pressure side (m3) and returning (m4) from the Compactor/Driver. (NOTE: Some smaller carriers utilize a check valve on the return side.)

  • Page 18: Return Oil

    “ON” (k5) and an “OFF” (k6) position. NOTE: When operating the NPK Compactor/Driver on a carrier with a return line shut- off valve, be sure the valve is turned to the “ON” position to prevent damage to the Compactor/Driver’s hydraulic motor.

  • Page 19: Prevention Of Contamination

    HYDRAULIC INSTALLATION PREVENTION OF CONTAMINATION A SHEET PILE DRIVER is harder on oil than using a bucket, so the oil is apt to deteriorate and breakdown sooner. Neglect of the oil system can not only damage the SHEET PILE DRIVER, but also cause problems in the carrier which could result in damaged components.

  • Page 20: Control Valves

    For excavators not equipped with an auxiliary or spare valve section as part of the control valve bank (k9), the NPK HYDRAULIC INSTALLATION KIT typically includes a solenoid operated, priority valve (k10) to operate the NPK Sheet Pile Driver (SD). The NPK MULTIVALVE is specifically designed for the operation of boom mounted attachments.

  • Page 37: Sheet/Pile Driving And Extracting

    SHEET/PILE DRIVING AND EXTRACTING SWIVEL FEATURE A free-turning swivel top (m7) is provided on models C6CSD, C8CSD and C10CSD NPK Sheet Pile Drivers. The self-aligning swivel feature minimizes carrier repositioning. The cylinder clamp assembly (sp3) can align to the job from any carrier position, over a wide range of boom positions.
  • Page 38 OPERATION The NPK Vibratory Sheet Pile Driver derives its power source from the excavator on which it is mounted. High efficiency is achieved through a combination of forces developed by the sheet pile driver and carrier machine: impulse force, vibration and downforce.

  • Page 39: Chucking The Sheet Pile

    OPERATION Keep personnel and bystanders clear of the SHEET PILE DRIVER (SD) while in operation. NO ONE should be under the unit! CHUCKING THE SHEET PILE 1. Turn the sheet pile driver frame manually until it is positioned in parallel to the sheet pile. Then chuck the sheet pile.

  • Page 40: Positioning The Sheet Pile

    OPERATION POSITIONING THE SHEET PILE 1. Using a pipe that is approximately 6 ft. (1.5 m) long or other suitable means, turn the sheet pile into position. 2. Insert the sheet pile into the last one installed, then drive it vertically with appropriate force.

  • Page 41: Pile Driving Operation

    OPERATION PILE DRIVING OPERATION 1. Make sure the sheet pile is in a vertical position. 2. If the speed of the sheet pile slows as it is going into the earth, give it proper pressing force in the vertical direction by operating the excavator to give it the vibrating speed that suits the nature of the soil so as to force the pile to drive into the soil faster.

  • Page 42: Pulling Operation

    OPERATION PULLING OPERATION Piles can be pulled out, in a way similar to that for driving, by giving an appropriate pulling force to the sheet piles in the vertical direction. Do not use excessive or unevenly distributed pulling force as the sheet pile in the chuck may be damaged. Make sure the sheet pile is in a vertical position.

  • Page 43: Operational Precautions

    OPERATIONAL PRECAUTIONS 1. Before starting operation, level and sufficiently compact the operation ground to prevent the excavator from falling down. 2. Do not touch the Sheet Pile Driver and hydraulic hoses during operation. 3. Do not use the Sheet Pile Driver for loading. 4.

  • Page 44: Storage Of The Sheet Pile Driver

    STORAGE OF THE SHEET PILE DRIVER 1. Make sure all whip hoses that connect the Sheet Pile Driver to the carrier are plugged (AS) and all hose (38) connections are capped (AR). Turn the shut-off valves (k4) to the “OFF” position. 2.
