ND-6.0 Internal Combustion Tamping Pick: This is a handheld internal combustion tamping pick, a specialized tool used for ballast tamping operations on railway tracks. The machine features a compact size, light weight, and portability, allowing for one-person, one-pick operation. It offers easy access to and from the track, excellent safety performance, low labor intensity, improved operational efficiency, and high tamping quality, meeting the requirements for tamping operations under various track bed conditions. It is suitable for daily maintenance and emergency repairs of railway tracks and turnout areas, making it an essential and ideal tool for railway track maintenance and repair operations.

1. Performance Characteristics: (1) The tamping pick uses an imported internal combustion engine as its power source, featuring a simple structure, light weight, and easy operation. The entire frame is made of aluminum alloy. It generates significant radial vibration force through the high-speed rotation of multiple built-in eccentric blocks,
simultaneously driving the pick head to vibrate. During operation, the pick head is inserted into the ballast of the track bed, and the vibration forces the ballast to compact under the sleeper, completing the tamping operation.
(2) The machine employs multi-stage vibration damping to isolate vibrations from the upper part of the tamping pick, reducing overall vibration and minimizing operator fatigue when holding the handles.
(3) The detachable wear-resistant pick head design allows for simple and convenient installation, as well as quick and easy replacement. The wear-resistant reinforcement ribs on the outer side of the pick head effectively enhance durability and reduce damage to the pick head body.
(4) Multiple machines can be grouped together to perform tamping operations on both sides of the sleeper simultaneously, improving operational efficiency.
(5) The machine has a simple and compact structure, is easy to operate, and is lightweight. It is designed for single-person, single-machine use, providing easy access to and from the track, effectively preventing human accidents, and ensuring traffic safety.

2. Structure, Working Principle, and Features:
① Structure: The ND-6.0 internal combustion tamping pick consists of an engine, clutch assembly, rubber vibration damping part, tamping pick head, tamping vibration part, and operating handles.
② Working Principle: The ND-6.0 internal combustion tamping pick operates by using a gasoline engine to rotate the clutch and transmission device, driving the eccentric blocks inside the tamping mechanism to rotate and generate high-frequency excitation force.
This causes the tamping mechanism to vibrate at high frequency. During tamping, the tamping mechanism is inserted into the ballast bed, and under the strong excitation force, the ballast is compacted and arranged through vibration, achieving the goal of compacting the ballast under the sleeper and completing the tamping operation.
