Figure 1: Trinity roller under construction
Road construction is inseparable from the roller, but for a long time, the road construction unit often encounters a selection problem when purchasing the roller—whether it is full hydraulic or mechanical. Which is more reliable? In fact, the data shows the most problem. From January to August this year, who is the most eye-catching in the road machinery market? The non-trivial one is the largest sales of its 20/22T all-hydraulic single drum roller. What are the fascinating "black technologies" of the Sany Roller? In no hurry, let us uncover the truth behind the "black technology" of Sany!

Truth: Who does it work fast?
As a construction party, the construction period is a benefit, and the quality of construction equipment directly affects the progress of the project. Roller, the most typical construction feature is the need to repeatedly roll back and forth. This puts forward the requirements for the efficiency of the roller turning back and forth.
Trinity hydraulic roller has stepless speed change, no need to wait for steering, can quickly turn, forward and backward, and mechanical roller in the steering, you need to step on the brake, step on clutch, shift, loose clutch, at least 3 to 5 seconds time. Calculating at a speed of 30 meters at a speed of 5 km/h, it takes 21.61 seconds for each pressure to be used by the Sany-Hydraulic roller, and 21.61+4=25.61 seconds for the mechanical type, and the hydraulic construction efficiency increases by 15.6%.
Truth 2: Who's eating less?
At present, the national environmental protection policy is increasingly strict. In particular, since the beginning of this year, local environmental protection law enforcement has been unprecedented. In some areas, registration and inspection of construction machinery used in new construction projects have begun. Excess emissions will be investigated and banned in accordance with the law. It can be said whether equipment is energy-saving and environmental protection has become an important factor directly affecting the vital interests of users.
The Trinity hydraulic roller has no impact on running and the power output is smooth without any sudden changes. The displacement is controllable and the fuel consumption is low. The commutation impact of the mechanical transmission is large and the power output changes greatly, especially at the moment of starting, a black smoke will be emitted from the exhaust pipe. On the site of the Guangxi Zangliu High-speed Section D, through comparison tests, the fuel consumption of the Sany single drive roller is 18.77L/h, and the mechanical type of a certain brand is 20.58L/h. The hydraulic single drive of the Sany hydraulics can save 10%.
Truth 3: Who is safer?
Safety responsibility is more important than Mount Tai. Any machinery must be constructed on the premise of ensuring safety, so that benefits can be discussed.
The Trinity hydraulic roller has triple protection for driving, parking and tight stop. The use of pumps and motors are interchangeable, the transmission method is simple, and the energy is increased, which can solve the racing phenomenon. At the same time, parking brakes, anti-locking settings, etc., to ensure a higher safety factor and higher reliability. Mechanical rollers have complicated pipelines and require frequent use of brakes. In the long term, the temperature of metal parts is too high, friction is weakened, and failures are high. There are certain safety risks.
Truth 4: Who is better to feed?
Listening to some users often, some devices are "affordable and can't afford it," because follow-up maintenance is too laborious, too expensive, and delays the schedule. Therefore, a good equipment, the later maintenance is equally important.
The Hydraulic System of the Sanyue Hydraulic Press is simple, easy to maintain, and basically maintenance-free. The mechanical structure and system are complex, requiring regular drainage, buttering the drive shaft, and regular replacement of wearing parts. In contrast, the hydraulic type is more convenient and more comfortable to use.
Truth 5: Who better to open?
Today's operators are mostly dominated by 80s and 90s. In the operation of driving, they will pursue more comfort.
The Sanyue hydraulic roller adopts a hydraulic single lever operation to achieve forward and backward operation. The operation is simpler and more convenient and easy to use. In this way, the owner is more likely to recruit operators and labor costs are lower. "Smooth, safe, and simple to operate" is a universal evaluation given to operators who have used the Sany Hydraulic Press. Mechanical roller clutch, brake, handbrake, shift, a lot, cumbersome operation, the operator's requirements are also high.
Truth 6: Who is good at work?
Quality is the foundation of engineering construction. Compaction flatness is one of the criteria for evaluating pavement construction. In the increasingly fierce competition in the project today, the construction quality of excellence will be an important weight to win the project.
The Sany all-hydraulic roller started smoothly and the road surface was compacted, eliminating the need for workers to repair the local road surface. The mechanical roller has a large starting shock and indentation on the road surface, which affects the construction quality.
Truth 7: Who is really good and cheap?
The Trinity 20/22T hydraulic single drum roller is a classic product that has been continuously improved and perfected by several generations. From the perspective of fuel consumption, labor, and post-maintenance, it can create more than the mechanical tonnage mechanical roller in the industry every year. The value of 50,000 yuan, therefore, countless powder, the market sales rose sharply, which is enough to prove that the full hydraulic roller has become a trend! (This article is from Trinity)
