SPZ-440 bidirectional ballast distributing and regulating machine, a newly-developed ballast regulator, can offer a brilliant traveling performance, i.e. a self-propelled speed of 100km/h and a towed speed of 120km/h. With two driver’s cabs, it is applicable to the ballast distributing and regulating and the ballast bed cleaning during railway construction, overhauling and maintenance, not only for the Chinese high-speed railways to be built, but also towards the existing railway speed increase, and therefore it is a piece of critical supporting equipment in the railway repair, speed increase, renovation and new railway construction units.

Equipped with a hydraulic drive, the machine is characterized by a state-of-the-art technology and perfect performance. The bogie adopts double damping structure, improving the self-propelled and towed speeds and switch traffic abilities, thus guaranteeing safety performance; the frame is made of solid structure, so that its strength and stiffness can meet the requirements for high-speed running of a long train formation; the side plow and middle plow can coordinate for the bidirectional ballast distribution and regulation, with the features of simple control and safe operation; the rotary middle plow device with innovative design and plug middle plow device may be additionally equipped, based on the customers’ needs so as to make the ballast distributing function more closely integrated with practice; the cleaning device has an extra cleaning power, thus able to effectively clean the ballast scattering over the sleeper, fastening and track side; the longitudinal corrugated sidewall conveyor belt and the ballast hopper can be used to store and distribute the cleaned ballast, and backfill the section with little ballast or notch left from ballast screening in order to achieve optimum utilization of ballast and provide orderly and beautiful lines after the ballast distributing and regulating work is concluded; the working safety and shutdown alarm system can identify the obstacles in a timely manner and give sound and light alarms during the side plow’s work, i.e., when the obstacles are within the minimum safe distance but the complete machine makes no response, it can shut down the entire machine and produce an alarm to ensure safe and reliable working; the ballast bed cross-section laser scanning system can compare the ballast bed cross-section upon regulating with the one of the standard ballast bed, and automatically calculate the excess or loss of ballast in the current section of line, hence guide the field ballast distributing and regulating operation, so as to achieve meticulous ballast management. 

The SPZ-200 bidirectional ballast regulator completes the ballast regulating operation for the ballast bed through the middle plow, side plow, wing plow and other working equipment to make the ballast uniform and the section of ballast bed formed according to the technical requirements. The cleaning device effectively cleans the ballast remained on the rail crossties and fastener and collect it to the conveyor belt to the ballast bed shoulder, in order to make the railway neat and beautiful.

DPZ-440 unidirectional ballast regulator is a newly developed ballast regulator. Shock-absorbing bogie is adopted to increase its self-propelled speed and coupling speed, improve the trafficability over turnout and guarantee the safe operation; the frame strength and stiffness have passed the static load test, and can meet the requirements for high speed action of large trailers.

The machine completes the ballast regulating operation for the ballast bed through the middle plow, side plow and other working equipment to make the ballast uniform and the section of ballast bed formed according to the technical requirements; local ballast connection and ballast complement features are added, and four kinds of cleaning devices are provided for crosstie face, rail side, vertical direction and fine operation to effectively clean the ballast remained on the rail crossties and fastener and collect it to the hopper. When a small amount of ballast is required for backfilling operations, backfill the ballast bed to reasonably use the ballast and make the railway neat and beautiful.
Newly developed side and middle plow devices have characteristics such as simple control and safe use. The advanced laser obstacle avoidance system, laser scanning system for section of ballast bed and PC (IPC) working control system can effectively measure and display the working results of the side and middle plows. The regulated section of ballast bed can be compared with the standard ballast bed graphically to automatically calculate the profit and loss situation of the ballast at this section of railway and create the data report. The complete vehicle is hydraulically driven with advanced technology, and it is safe and reliable.
