The hydraulic lifting freight elevator is a specialized type of equipment that requires careful inspection. As such, it is a key concern for users and operators. According to the "Regulations on the Supervision and Administration of Special Equipment," hoisting machinery refers to electromechanical devices used for vertical lifting or combined vertical and horizontal movement of heavy objects. This category includes elevators with a rated capacity of 0.5 tons or more, cranes with a rated weight of 1 ton or more and a lifting height of 2 meters or more, and electric hoists with fixed load-bearing structures.
On the market, there are two main types of hydraulic freight elevators: scissor-type and rail-type. These systems typically do not have enclosed cabins but instead use simple protective railings and doors. Due to the strict definition of elevators in national regulations, the "Special Equipment Safety Supervision Regulations" specify that elevators are power-driven machines that move along rigid guides or steps along fixed paths, designed to transport people or goods. This means that the hydraulic freight elevators we are discussing are strictly for cargo and must not be used to carry passengers.
Scissor-type hydraulic freight elevators with a capacity over 0.5 tons fall under the category of lifts. According to regulations, they must be inspected by the local Quality and Technical Supervision Bureau before installation. During the inspection process, the manufacturer must provide documents such as the special equipment production license, installation permit, installation notice, installation plan, sales contract, product delivery certificate, operation and maintenance manual, and important parts warranty information. After installation, the bureau will conduct an on-site inspection according to national standards. Only after passing the inspection can the equipment be put into service. Once in use, regular inspections by the local bureau are required.
Rail-type hydraulic freight elevators with a load capacity over 0.5 tons are also considered special equipment, and they must be reported accordingly. However, currently, there are no specific inspection procedures established for this type of equipment. As a result, many rail-type hydraulic freight elevators available on the market today are not subject to formal inspections. With their growing popularity, it is expected that the government will soon introduce standardized supervision and inspection protocols. Some organizations are already conducting research on rail-type hydraulic lifts, and it is anticipated that proper inspection procedures for these systems will be introduced in the near future.
stainless steel commercial flat washers are used under bolt heads or nuts to increase the bearing surface area, or to offer protection so that the nut or bolt can be rotated without distortion of the bearing surface. Flat washers are also used to give tightness to a joint, to prevent leakage, and especially to distribute pressure under the head of a bolt or nut. Dimensional specifications are governed by ASME B18.21.1. Commercial flat washers generally have a larger outer diameter than SAE (Society of Automotive Engineers) flat washers, and can be utilized in nearly any application. stainless steel fasteners are commonly used in applications that require general atmospheric corrosion resist ance, such as chemical and food processing equipment. Stainless steel has a higher corrosion resistance than carbon steel.
