ND-4K Internal Combustion Tamping Pick

ND-4K Internal Combustion Tamping Pick: A small railway maintenance tamping machine suitable for the upkeep of railway track beds, used for tamping operations on ballast beds. It is a tamping device that allows for quick on-and-off track movement and easy operation, particularly ideal for switch tamping work.

Features:
1. Novel design and compact structure. This machine adopts a design where the gasoline engine is directly connected to the tamping device, primarily composed of the gasoline engine, vibration damping device, universal drive shaft, vibrating body, and handle, forming an independent and complete handheld tamping pick. It is structurally rational, robust, durable, and user-friendly.
2. Lightweight, convenient for on-and-off track movement. The connection from the vibrating body to the handle utilizes a three-stage vibration damping system, offering excellent damping effects and reducing fatigue.
3. High excitation force, large amplitude, and easy insertion into the track bed, significantly improving work efficiency and tamping quality.
4. The power transmission employs a universal drive shaft method, ensuring reliable operation, long service life, and low failure rate.
5. The connection between the vibrating body and the machine uses a patented anti-loosening device, making maintenance and servicing more convenient. It can be repaired and maintained on-site without the need for special tools. It is an ideal portable tamping pick.
This product has obtained one national invention patent and three national utility model patents. It has passed the scientific and technological appraisal by the Shanghai Railway Bureau and the CRCC certification by the China Railway Certification Center.

Preparations Before Use
1. Check whether all fasteners and connection parts are secure and reliable, and ensure none are missing;
2. This machine uses a two-stroke gasoline engine, with fuel being a mixture. Strictly follow the engine manual's requirements for the fuel mixing ratio (each machine is equipped with a fuel mixing pot). Use 93-octane unleaded clean gasoline and imported Mobil brand two-stroke engine oil or Komatsu specialized two-stroke engine oil. Fill the power fuel tank with fuel;
3. After verifying all parts are correct, start the engine for use.
