Precautions for hydraulic freight elevators
Factors such as price and configuration are more important when purchasing hydraulic freight elevators. The customer must understand the service objects, carrying capacity, work performance and the size of the hydraulic freight elevator required by the civil design requirements of the hoistway, machine room, etc., so as to be more conducive to choosing their own elevator. Specific reference can be made from the following aspects:
1. The actual situation of the hoistway: the hydraulic freight elevator can be installed in a closed hoistway environment. The actual condition of the hoistway determines the specifications and dimensions of the final hydraulic freight elevator. Specifically, it includes the width, depth, pit, and machine room of the shaft.
2. Rated load capacity. The elevator load (kg) specified by the manufacturing or design is the main parameter of the hydraulic freight elevator. Generally, there are 1000kg, 1500kg, 2000kg, 3000kg, 5000kg and other specifications to choose , and it can also be designed according to non-standard requirements.
3. Rated speed. The elevator speed specified by manufacturing or design, in M/s, is the main parameter of the elevator. The general speed of hydraulic freight elevator is 0.25m/s and 0.2m/s, and the maximum speed cannot exceed 0.5m/s under special circumstances.
4. Platform size. The platform size of a general hydraulic freight elevator can be understood as the outer net size and the inner net size, expressed in width * depth * height, but the former is mostly used by customers, and the latter is mostly used hydraulically. The reason is that customers consider their own use effects. Hydraulic freight elevator manufacturers can calculate the size of the hoistway more conveniently. Therefore, customers must confirm the size of the freight elevator platform that they need to quote.
5. Lifting height. The height of the hydraulic freight elevator from the bottom to the top. It must be accurately measured, because the lifting height determines the length of the hydraulic cylinder, and the price of the hydraulic cylinder is relatively expensive.
6. The height of the top layer. The height of the elevator from the bottom station to the top station is also important, because the top height must meet the acceptance criteria.
7. The number of floors of the freight elevator also affects the price.
