1. The closed-loop vibrating hydraulic system is applied. With double-frequency and double-amplitude, its scientifically reasonable static linear load and exciting force configuration guarantees the effective compacting for the materials of diversified types and the pavements of diversified thicknesses.
1. The hood of large opening angle eases the maintenances of engine and hydraulic system.
2. All maintenances points can be fulfilled on the ground.
3. The traction hydraulic system can be used for short-distance towing.
