KOMS has national (special equipment) certification and core technology (clean, explosion-proof) lifts, which can be widely used in various logistics centers, automobile manufacturing industry, new energy industry, robotics industry, LCD display manufacturing industry, food, medicine, chemical industry, Military industry, shipbuilding industry, computer chip workshop, spraying workshop, dust-free workshop, and other industrial automation logistics production lines. It completely solves the problem of customized vertical logistics transportation in ordinary, clean grade or explosion-proof places. The maximum load of this product can reach 3 tons, the car area is 8.7 square meters, the minimum is 3m on the top floor, and the minimum pit is 500mm. There are ordinary type, marine type, and clean type. The cleanliness level can be achieved in the thousands, 10,000, 100,000 and other series. Not only does it have all the functions and safety factors of traditional freight elevators, but it can also pass and obtain the safety use certificate issued by the technical supervision department like ordinary elevators. No machine room (the height of the top floor only needs 3 meters) and no bottom pit (the depth of the bottom pit only needs 0.5 meters). It can be customized and seamlessly connected with the existing assembly line. The spirit of the document "Shanghai Quality Technical Supervision Special [2016] No. 381", in order to cooperate with relevant supervision departments to strengthen the safety inspection of simple lifts, regulate the manufacture and installation of simple lifts, improve the safety status of simple lifts, and prevent and reduce simple lift accidents, Focused on the simple rectification of simple lifts throughout the city, we launched this simple lift for our industry (3T, car area of 8.7 square meters, top floor of 3m, bottom pit 500mm inspection certificate), cost-effective, the following Is my company's production qualification for simple lifts, hydraulic traction of two product types Test qualification report, acceptance certificate of technical supervision department, and on-site photos of the product used in BMW spray shop.

For the above elevator products, the standard area of 1T elevator products is ≤2.4 m² (standard maximum area of 1T freight elevator is 2.4 m², GB7588-2011), the maximum area is ≤3.6 m² (standard maximum area of 2T freight elevator is 4.2 m²); ≤4.2 m² (standard maximum area of 2T freight elevator 4.2 m²), maximum area ≤6.3m² (standard maximum area of 3T freight elevator 5 m²); standard area of 3T elevator products≤5 m² (standard maximum area of 3T freight elevator 5 m²), The maximum area is ≤ 8.7m² (the standard maximum area of a 5T freight elevator is 9 m²). In summary, the maximum load capacity of the lift product can reach 3 tons, the car area is 8.7 square meters, the minimum floor is 3m, and the minimum pit is 500mm. There are ordinary type, marine type, and clean type. The cleanliness level can be thousands, 10,000, 100,000 and other series, not only has all the functions and safety factors of traditional freight elevators (according to the requirements of standard specifications, for safety, only goods can be carried, not people!), Like the standard elevator, it can pass and obtain the safety use certificate issued by the technical supervision department, and it has no machine room (the height of the top floor only needs 3 meters) and no bottom pit (the depth of the bottom pit only needs 0.5 meters). The effective area is large: 3T elevator products It is equivalent to the area of a 5T freight elevator that has a higher cost performance than a 5T machine-room-less freight elevator and can be customized to design, seamlessly docking with the existing assembly line, and other advantages.

Working principle of simple elevator drive system
During operation, the hydraulic oil forms a certain pressure through the hydraulic pump, enters the lower end of the hydraulic cylinder through the oil filter, single direction valve, throttle valve, so as to make the piston of the hydraulic cylinder move upward and operate the lifting function.

The hydraulic cylinder moves under the piston (i.e. the weight drops). The hydraulic oil returns to the oil tank through the electromagnetic reversing valve and throttle valve.

In order to make the weight drop stably and brake safely and reliably, an overflow valve is set on the oil return road to keep the flow constant, so that the lowering speed is not changed by the weight, and the flow is adjusted by the throttle valve to control the lowering speed.

SECURITY WISDOM MANUFACTURE
In order to cooperate with the document spirit of the notice of Shanghai Bureau of quality and technical supervision on carrying out the special renovation work of the simple elevator (hjjjt [2016] No. 381), to cooperate with the relevant supervision departments to strengthen the safety supervision of the simple elevator, standardize the manufacturing, installation, and use of the simple elevator, and raise the safety condition of the simple elevator, In order to prevent and reduce the accidents of the simple elevator, we focus on the special renovation work of simple elevator in the whole city. We have launched this simple elevator product that we use in industry, which can achieve a 3T car area of 87 square meters, a top layer of 3M, a pit of 500mm, and high-cost performance. The following is the qualification report of our company on the production of a simple elevator and the type test qualification report of two products of hydraulic traction
