Introduction of hydraulic lift freight elevator inspection method for hydraulic lift equipment

The hydraulic lifting freight elevator is also a special type of elevator. Therefore, the inspection of the hydraulic lifting freight elevator is a problem that users are more concerned about. The "Special Equipment Safety Supervision Regulations" appendix specifies that: hoisting machinery refers to electromechanical equipment used for vertical lifting or vertical lifting and horizontal movement of heavy objects, and its scope is specified as an elevator with a rated lifting capacity greater than or equal to 0.5t; Cranes with rated lifting weight greater than or equal to 1t and lifting height greater than or equal to 2m, and electric hoists with fixed load-bearing form.

There are two main types of hydraulic lift freight elevators on the market: scissor-type hydraulic lift freight elevators and rail-type hydraulic lift freight elevators. We call the hydraulic lift freight elevators without cars, only simple protective railings and simple protective doors. Because the country has a strict definition of elevators, the "Special Equipment Safety Supervision Regulations" annex has express provisions: elevators refer to power-driven, using boxes running along rigid guides or steps (steps) running along fixed lines. Or electromechanical equipment that transports people and goods in parallel, including manned (cargo) elevators, escalators, moving walkways, etc. The state has strict elevator supervision and inspection procedures. The hydraulic lift freight elevator we are talking about can only be used to carry cargo, and it is not allowed to carry people.

The scissor type hydraulic lift freight elevator with a load of more than 0.5t is a kind of lift. According to the regulations, it should be submitted to the local quality and technical supervision bureau for inspection before installation. When the inspection is carried out, the special equipment for the lift will be produced by the manufacturer of the hydraulic lift freight elevator. License, special equipment installation license, installation notice, installation plan, sales contract, product delivery certificate, operation and maintenance instructions, important parts and warranty books, etc. After the installation is completed, the local quality and technical supervision bureau will conduct on-site inspection according to the relevant national supervision and inspection regulations. After the inspection is qualified, it can be used. The hydraulic lift freight elevator after use should be inspected by the local quality and technical supervision bureau according to the regulations.

For the hydraulic lifting freight elevator of the rail-type hydraulic lift http://equipment with a load of more than 0.5t, although it is also a special equipment, it should be reported according to the regulations, but the country has no corresponding supervision and inspection procedures for this product, so the current market The rail-type hydraulic lift freight elevators sold on the market can not be inspected. With the increasing market share of the rail-type hydraulic lift freight elevators, the state will definitely introduce corresponding supervision and inspection procedures. Now some units have begun to study the rail-type hydraulic lifts. For the inspection of freight elevators, it is believed that there will be supervision and inspection procedures for rail-type hydraulic lift freight elevators soon.
