Road roller can be divided into hydraulic type and mechanical type. excavator Discussions have been generated about the comparison of the two types in different aspects. The comparison mainly focuses on efficiency, safety, environmental protection, maintenance, price, reliability and comfort. The mechanical roller has no front wheel drive and its working speed is fixed. excavator price The hydraulic one adopts full-wheel drive, which allocates more power to the vibrating drum, improving the compactness and reducing the compacting times, having more advantages in improving efficiency. And the hydraulic type needs no stop in the travelling process, improving 10% in efficiency than the traditional mechanical one. crawler excavator For safety, braking is an important factor that decides whether the machine can be stopped immediately once emergency happened. The brake of the hydraulic one combines with the joystick and can be locked when emergency happened. Hydraulic Excavator The brake and joystick of the mechanical one is separated, which may cost more time for the operator to stop the machine under urgent situation. Thus, the hydraulic roller has higher safety than the mechanical one, especially in mountainous area and dam construction. Also, the hydraulic type does a better job in heat dissipation than the mechanical one. The hydraulic type can be used in extreme temperature ranging from -40℃ to 60℃. And the hydraulic type is easier to be maintained. Mini Excavators for Sale Although the hydraulic roller has higher price than the mechanical one, its advantages in high efficiency, high reliability, environmental protection, safety and ease of maintenance are obvious. wheel excavator All of the industry experts, representatives and media believe that the hydraulic type has huge market potential in the future.
