Concrete finishing is not an easy job. During construction, workers' hands, backs and knees are easily injured. The advent of trowels allows construction workers to stand and operate when finishing concrete. Based on the size of the project, the number of people and the customer's requirements for the surface layer, the construction party can consider purchasing a trowel. If you are a construction party specializing in concrete coloring, dyeing or home decoration polishing, you may not need to buy a ride-on trowel (double-disc machine). This type of trowel is not only expensive, but also has a higher hardness after finishing, and there is no such high requirement for the above-mentioned types of floors. In fact, a walk-behind trowel is sufficient to meet the work requirements of small-area floor slurry finishing.
Under what circumstances should you consider investing in a trowel? Generally speaking, the construction area is an important consideration. "Even small-area projects can use trowels, even if the project is only a few hundred square meters. As long as the construction area reaches 100 square meters, a trowel must be used. If it exceeds 300 square meters, a small ride-on trowel must be considered." From another perspective, the working efficiency of a single-disc trowel is equivalent to that of three construction workers using traditional manual finishing tools such as scrapers.
It seems that the biggest advantage of the trowel is to increase the construction speed. But this is only a one-sided understanding of the advantages of the trowel. The trowel does not simply increase the speed but the efficiency when dealing with large-area construction. To put it further, the trowel allows the construction party to choose a more appropriate time to start the machine when dealing with large-area construction, instead of having to start early because of the need to consider the overall area of construction like traditional construction.
Operation steps for trowels:
1. Before use, check whether the motor, electrical switch, cable and wiring are normal and meet the regulations, and install a leakage protector.
2. Before use, check and clean the debris on the trowel to avoid the whole machine jumping during use.
3. After the power is turned on, the test run is carried out. The blades rotate in a clockwise direction and must not be reversed.
4. The operator should wear insulating shoes and insulating gloves. The cable is carried by the assistant, who should also wear insulating shoes and insulating gloves. Be careful to prevent the cable insulation layer from being scratched and causing electric shock accidents.
5. If the trowel fails, it needs to be shut down and the power is cut off before it can be repaired.
6. The trowel should be stored in a dry, clean environment without corrosive gases. The handle should be placed in the specified position. It should not be loaded and unloaded rudely during transfer.
Construction precautions:
1. During construction, pay attention to the temperature of the motor reducer not exceeding 80°
2. The oil of the turbine box needs to be checked frequently. If it is lower than the oil mark, please add oil in time. The machine should be cleaned in time after each use, especially the wiper should be clean and stored in a dry, clean and non-corrosive environment. When the wiper is worn to 30mm on one side, loosen the nut, turn the wiper around and tighten the screw again to achieve the purpose of using two pairs. The angle of the trowel can be adjusted by turning the hand wheel to achieve the ideal effect of rough trowel. If you need to stop the machine during construction, please turn off the power in time. When the gasoline engine stops, press the switch on the handle in time to stop the machine.
The floor effect after the trowel is processed is more uniform, the construction speed is faster, and the operation is more convenient. Long-term operation with a handheld trowel will easily fatigue the construction worker's knees, shoulders and elbows, which will affect the construction effect. Simply put, using a trowel makes the originally difficult operation easier, and it is a better equipment for floor finishing.
