VV 71 PD

VV 71 PD
The VV 71. PD roller consists of the front part in which the vibratory ruuning surface is resiliently mounted and the rear part which consists of the axle, driving set and cabin. Both parts are connected by the joint. The drive  of the travel vibrations and steering mechanism is taken from the Diesel engine over the mechanical drive of the hydroelectric generators to the hydrostatic converters. The hydrostatic drive allowes for an infinite variation of travel speed in forward and backward direction. The design of the exciter in the vibratory running surface allows for the option of two different eccentric moments and two associated values of the working frequency of the vibration exciter selected, in advance, from the driver ´s cabin. The driver´s position together with the cabin is resiliently mounted on the rear frame. The mentioned mounting is specially designed so that no vibrations from the engine or vibratory running surface may be transmitted into the cabin.The driver´s position and the cabin are sufficiently sound - proof. The roller is intended for the compacting of all kinds of soil. It is, especially, suitable for the compacting of coherent soil of 30 to 40 cm thickness. Only non - coherent soil can be compacted in thicker layers. The roller can also be used for the disintegration, homogenization and the compacting of soft and disintegration soil.
