The problem,movement is not synchronous and polling power is imbalance,which is found in 08-32 tamper s moving drive system,has been analysed.

This paper puts forward the design and realization method of the digital multi-channel recorder based on tamper,that is,the recorder adopts the layer-controlled hardware structure with Window CE embedded system as system platform and realizes the real time recording and control of recording software through main and subsidiary thread structure and data-driving mode.

Analysis on high temperarture malfunction and prevention method for railway tamping machine s hydraulic pressure system;

Electric control system for D09-32 continuous tamping machine;

Laser lining system of 08 32 tamping machine;

From the angle of the mathematical and geometrical bases,this paper makes brief discussion on the compensation of the lining and measuring system in D09―32 continuous tamping machine,emphatically introduces the compensation principles of the "three points" lining operation and "four points" lining operation,and probes into the lining compensation control of the traveling bogie.

The paper points out how to grasp the distillation of tamping coking technique from theoretical side and practical side, and introduces the influence of tamping and coking on coking process and coke quality.

The environmental protection characteristic of hot recovery tamping coke oven is analyzed from the aspect of pollutant produce tache, environmental protection measures, pollutant discharge quantity and technical economic etc .

This paper expounds the problems existing in tamping machines and the improvements of tamping and pushing schemes, and makes comparison of different schemes.
