There are several ways of contracting a decoration company. The contracting and packing materials are only a broad classification of the contracting methods of decoration companies. The following are several types of contracting methods adopted by the decoration company in the task of decorating household homes entrusted by the contracting users: 1. The contractor does not include materials. . The user prepares all kinds of decorative materials, and the decoration company only supplies materials. This kind of contracting method is suitable for users to be more proficient in decorative materials, but also has the time, ability to purchase materials, decorative works is relatively simple, there are few cases of decorative materials. Users and decoration companies only settle labor costs, indirect expenses, etc., and decoration companies cannot make profits from material fees. Users can save some decoration costs, but the procurement of materials is very energy-consuming. Second, the contractor package accessories. Users prepare their own decorative main materials such as floor tiles, paints, glazed tiles, wallpapers, wooden floors, and sanitary ware. The decoration company is responsible for the construction of the decoration project and the procurement of auxiliary materials such as cement, lime, sand, and stones. This kind of contracting method is suitable for users who have the ability to discriminate the main material of the decoration, and has the time and energy to purchase, and the variety of decorative main materials is not many. Users and decoration companies only settle labor costs, machinery use fees, auxiliary materials fees, and corresponding overheads. Decoration companies can benefit from labor, auxiliary materials and indirect costs. Users can worry less about purchasing auxiliary materials, but it is also very difficult to purchase materials. Third, the contractor package all materials. The decoration company will be responsible for the construction of the decoration project tasks and the purchase of the materials used by the decoration company according to the design and requirements of the users. This kind of contracting method is suitable for users who are not familiar with the decoration materials and have no time or ability to purchase materials. The decoration company can purchase a variety of decoration materials according to the user's requirements, and the variety of decorative materials and other situations. The disadvantages of adopting the contracting method without material inclusion are: the user knows little about the texture and use of the material; it is easy to buy materials with high quality and low price; because the purchase amount is small, the wholesale price provided by the material shop cannot be enjoyed, and the freight is high; once the project is completed After quality problems occur, it is the quality of the process or the quality of the material. The responsibility is not clearly distinguished; workers are prone to waste during construction and leftovers cause some waste. The use of contracted materials, the premise is based on the full trust of the decoration company, so that users can worry less about home decoration. Because the home decoration construction period is at least one or two months, users are busy and busy in this period. For this reason, it is a good idea to entrust the high-renovation decoration company with full contract. Pay attention to the formal decoration company with high transparency.

In other words, lowering the speed increases the torque. A planetary gearing system has a ring gear with a sun gear at its center and three planetary, or pinion gears, equal distances apart from each other that rotate around the sun gear. The shaft that connects the hydraulic travel motor to the Final Drive gearbox turns the sun gear at a super-high speed. The planetary gears mesh with the sun gear and turn while rolling around the ring gear. They spin at a slower rate than the sun gear, and that speed reduction increases torque.
