In this work, vibrations were investigated during loading and unloading operations of mobile agricultural machines, which are considered to be one of the most labor-intensive components of the transport process. Therefore, idle machines during carrying out operations and in anticipation of them remain quite significant, which is due to the insufficient level of mechanization of loading and unloading of cargoes on transport, with a fuzzy coordination of actions of different organizations in the overloading of loads at transport nodes and for some other reasons. The main means of mechanization are stationary and gantry cranes for containers, heavy loads and large packages, as well as means of mechanization on the railway or on the chassis of a standard mobile car or special chassis.

In our opinion, the use of hydraulic impulse actuators in the production of vibration and vibration shock unloading devices is promising, due to the simplicity of construction, compactness, high energy intensity, a wide range of regulation of operating parameters and the ability to work in automated mode. In particular, a promising area is the creation of removable attachments with hydro-impulse drive for dump trucks, onboard vehicles, tractor trailers and other vehicles. For intensification of processes of unloading of a body of a trailer-dump truck of tractors the hydraulic vibrating shock device is developed. It accelerates the unloading and cleaning of the body of agricultural products. Reduced costs and reduced oversized idle tractors with unloading trailers.

Therefore, the development of vibration and vibration impact equipment for use in loading and unloading operations on mobile agricultural machines and in general on transport is an urgent task.
