The S840 laser screed is an advanced ride-on laser screed researched and developed by my company, and it is characterized by its higher screeding efficiency, higher automation, very robust power and lesser failure rates. Now I will give its optimal summary as follows:

  1. All the fittings of the S840 laser screed are purchased from the world-class manufacturers.

The product introduction has made a detailed explanation for the specific configuration of this machine(s840-2 laser screed for sale ), so now I will make a more specific explanation for its engine and its hydraulic fittings.

Firstly, the S840 laser screed has adopted the 31 horsepowers American Quantum gasoline engine, this kind of engine is a very mature product made by the Quantum company, and it is characterized by lesser failure rates and very robust power. While in the current market, most of the clients have adopted the Honda GX690 engine, the power of this kind of machine is tagged as 24 horsepowers but its actual power is around 19 horsepowers, so using this kind of less powerful engine will make the machine start with back pressure(when you start the machine, the pressure gage will point to the intermediate position.). When working in this kind of circumstance for a long time, the service time of the machine will be severely influenced, while the high-powered engine applied in the s840 usually starts at the pressure of 0, so this engine can drive its hydraulic system without pressure.

Then it is the hydraulic system of the s840 laser screed, it has adopted the Rexroth hydraulic system which currently (2017) ranks first in the world. And the 28cc hydraulic pump has provided dynamic hydraulic power to the machine, while in the current market, many manufacturers have applied the Danfoss low-end hydraulic system with a 16cc hydraulic pump in their own products, which results to the insufficient power of those laser screed products. And when walking on the relatively thicker concrete, the resistance borne by the machine is quite big. So if a very good power output can not be assured, this machine will only be able to walk slowly or be unable to walk, and meanwhile it will also severely influence the service life of this machine. Benefiting from its robust power system, the s840 laser screed can walk normally in the concrete which is 30 centimeters deep.

Reasonable structure and optimized details

The S840 laser screed has adopted an articulated design(The advantages of the laser screed in articulated design), the screed head with a tilt sensor can make an effective adjustment for the levelness of the screed head, so it can accomplish a very effective and perfect screed performance. And besides this, we have also retrofitted a height measuring point, so that the operators can set the machine more accurately, and the cooling fan of this machine can be turned on or turned off manually, so it can save the electricity consumption of this machine, and the service life of its battery can be improved. And it has adopted an electronic control conversion valve, and it is equipped with a speed-control knob, which can control the speed of this machine accurately, improve the operating stability of it, and finally improve its screed effect.

Besides what has been mentioned above, the s840 laser screed also has many other advantages in some specific aspects, but now I will not introduce them one by one. All in all, we can confidently say that the s840 laser screed produced by HIKING is currently the most advanced ride-on laser screed product all over the world.
