ПТС 4.

Purpose and Design Features of the PTS-4

The PTS-4 tractor dump trailer is a specialized transport vehicle designed for hauling various agricultural loads on all types of roads and in field conditions. The model's primary specialization is the transportation of bulk, loose, and piece goods. Structurally, the trailer is single-axle, providing high maneuverability when operating in confined spaces, on narrow country roads, and around turns where multi-axle trailers may be difficult to handle.

Technical Specifications and Load Capacity

The nominal load capacity of the PTS-4 is 4 tons, which is an optimal indicator for working in tandem with tractors of the 0.9–1.4 traction class (e.g., MTZ-80/82). The internal dimensions of the body allow for the transport of both bulky light loads and dense agricultural materials. The platform's internal volume can be increased by installing additional side panels, which significantly enhances efficiency in transporting grain crops, haylage, or light organic fertilizers.

Hydraulic System and Unloading

The platform tilting mechanism is powered by a high-performance hydraulic cylinder connected to the tractor's hydraulic system. The PTS-4 features a rear-unloading system, requiring minimal preparation time for the unloading site. The working pressure in the hydraulic system is standard for most domestic tractors, eliminating the need for modifications to the trailer hitch. The platform's tilt angle ensures complete discharge of the load without residue in the trailer.

Chassis and Braking System

The chassis is based on a reinforced single-axle trolley with high-pressure pneumatic tires. This design minimizes rolling resistance on loose soil. The PTS-4 is equipped with a pneumatic service braking system acting on the trailer wheels, ensuring safe operation when driving on public roads at full load. A manual parking brake securely locks the trailer during parking or loading and unloading operations.

Application in Agricultural Operations

In a farming environment, the PTS-4 is indispensable during the harvest season, providing logistics from the combine harvester to the grain storage facility. The trailer is also actively used for spreading fertilizers, transporting seeds, and moving tools. The ability to operate as part of a road train allows for the rapid relocation of cargo between fields located at significant distances from one another. The low loading height simplifies manual loading processes whenever necessary.

Reliability and Maintenance

The frame structure is crafted from high-strength channel bars resistant to cyclic loads and twisting when driving over uneven terrain. Regular maintenance involves lubricating hub assemblies, checking tire pressure, and ensuring the hydraulic cylinder is leak-free. The simplicity of the assembly components makes field repairs possible without the need for specialized service equipment, which is critical during peak operational seasons.

Who Should Use This Equipment

The PTS-4 is an ideal choice for small farms and private estates. Due to its versatility, it covers 90% of the transport tasks of a small agricultural enterprise. Its low cost of ownership, combined with high reliability, makes it the most sought-after trailer in the under-5-ton segment, offering an optimal balance of price and functional capability.
