The classification of freight elevators, whether the freight elevators are considered special equipm

Hydraulic freight lift is a very widely used cargo vertical transportation equipment that uses hydraulic pressure as the lifting power, drives the oil pump through the motor, and relies on the oil cylinder to drive the heavy-duty chain to drive the hydraulic lift freight elevator to lift flat. Let's take a look at the advantages of hydraulic freight elevators: Hydraulic freight elevators have advantages that freight elevators do not have in terms of safety and stability, operating costs, civil engineering, and freight elevators

Safety and stability advantages: The hydraulic lift freight elevator is equipped with the safety device of the traditional traction elevator at the same time, and is also equipped with: relief valve

It can prevent the system pressure from being too high during the upward movement: when the system fails, the manual pump can be operated to pump out high-pressure oil to make the car rise to the nearest floor position; Pipeline rupture valve: When the hydraulic system pipeline is ruptured and the car stalls and falls, it can automatically cut off the oil circuit to stop lowering the oil temperature of the fuel tank

According to the type, the elevator can be divided into: scissor elevator and guideway elevator. The lifting height of the lift freight elevator ranges from 1 meter to 30 meters, and the lift freight elevator with special specifications can be customized according to user requirements.

Scissor lift freight elevator is a widely used special equipment for aerial work. Its scissor mechanical structure, so that the lifting platform has higher stability, wide working platform and higher bearing capacity after lifting, so that the range of aerial work is larger, and is suitable for many people to work at the same time. It makes working at height more efficient and safer.

Product features: The lifting mechanism is made of high-strength manganese steel giant tube. It is equipped with a safety protection device to prevent the lifting platform from overloading.

It is equipped with a safety protection valve to prevent the rupture of the hydraulic line. There is an emergency lowering device in the event of a power outage. The product is suitable for mobile aerial work such as installation and maintenance of aerial equipment in various industries.

According to different requirements, different power forms can be selected (such as: three-phase AC power supply, single-phase AC power supply, DC power supply and internal combustion power, etc.), with manual hydraulic devices, it can be lifted and lowered as usual in power failure or no power supply place, and a telescopic platform can be added, which can be extended to the required position when the platform length is insufficient, so as to improve work efficiency. It is an ideal equipment product for modern tall buildings and equipment, and a must for high-altitude safe and civilized production.

The guide-rail fixed lift freight elevator is a non-scissor lifting platform. It is suitable for the transfer of goods between the floors of industrial plants, restaurants and restaurants on the second and third floors. The minimum height is 150-300mm, and there is no need for an upper hanging point.

Variety of forms (single-column, double-column, four-column). The equipment runs smoothly, the operation is simple and reliable, with hydraulic and electrical protection, and the cargo transmission is economical and convenient. Guide-rail fixed hydraulic lift, widely used in industrial and mining enterprises to replace elevators to lift goods, with simple structure, large load capacity, long service life, convenient maintenance, safety and practicality, especially suitable for the underground with shafts can not dig the foundation of the place.

The elevator does not belong to special equipment, because according to the relevant policies on lifting equipment issued by the Quality Supervision Bureau and other relevant departments in November 2014, it is clearly stipulated that the lifting platform is no longer a special equipment, and there is no need for filing and inspection. Therefore, customers do not need to prepare various materials and go through various procedures.

Lift freight elevators are special equipment.

Special equipment refers to boilers, pressure vessels (including gas cylinders, the same below), pressure pipelines, elevators, lifting machinery, passenger cableways, large-scale amusement facilities and special motor vehicles in the field (factory) that involve life safety and are more dangerous.

Among them, boilers, pressure vessels (including gas cylinders), and pressure pipelines are special pressure-bearing equipment; Elevators, lifting machinery, passenger ropeways, and large-scale amusement facilities are special mechanical and electrical equipment.

Hydraulic Elevator Advantages:

1. The hydraulic elevator adopts the most flexible side-mounted machine room (within 10 meters from the shaft), and there is no need to set up the traditional top-mounted machine room with a large floor area, high civil engineering requirements, high project cost and affecting the building structure and appearance.

2. The lowest meter on the top floor of the special hydraulic elevator and the lowest meter on the rest of the floors can be installed.

3. The hydraulic elevator is not equipped with a counterweight device, which improves the utilization rate of the shaft area, and the car can be larger.

4. When the hydraulic elevator is running, the vertical load such as the weight and load of the car are directly applied to the pit foundation through the oil cylinder, and the strength requirements for the wall and top of the shaft are relatively low, and the pure brick structure or brick-concrete structure shaft can be.

5. The hydraulic elevator can provide many years of experience in the integrated steel structure shaft, sealed with high-quality double-sided sandwich color steel plate, users only need to provide pit and installation space, they can enjoy convenient, fast and safe integrated hydraulic elevator and related services.

Hello, if the rated lifting capacity is greater than or equal to, it belongs to the scope of special equipment management.

For details, see: Announcement No. 114 of 2014 of the General Administration of Quality Supervision, Inspection and Quarantine on Amending the Catalogue of Special Equipment

Lifting machinery refers to the mechanical and electrical equipment used for vertical lifting or vertical lifting and horizontal movement of heavy objects, and its scope is specified as a lift with a rated lifting capacity greater than or equal to; Cranes with a rated lifting capacity greater than or equal to 3t (or tower cranes with a rated lifting moment greater than or equal to 40t·m, or loading and unloading bridges with a productivity greater than or equal to 300t h) and a lifting height greater than or equal to 2m; Mechanical parking equipment with more than or equal to 2 floors.

The lifting platform is no longer a special equipment, and there is no need for filing and inspection.

There are more than 160 kinds of lifting work platforms, mainly including, guide rail chain lifts, guide rail lifting platforms, guide rail lifting freight elevators, loading and unloading platforms, mobile scissor lifts, fixed scissor lifts, aluminum alloy lifts, sleeve cylinder lifts, truck-mounted lifts, lifting stages, rotating stages, lifting rotating stages, curved arm lifts, self-propelled lifts, aerial work vehicles, boarding bridges, etc.

Summary. Hydraulic freight elevators are not considered special equipment. Hydraulic lift freight elevator belongs to the category of lifting work platform, in 2014 the country issued a new special equipment catalog, the elevator was simplified, only the simple lift and construction lift were retained, the lifting platform was deleted, the hydraulic lift freight elevator no longer belongs to the special equipment, no longer belongs to the scope of special equipment safety supervision, no need to report for inspection.

Hydraulic lift freight elevator belongs to the hydraulic lift freight elevator is also called material hoist, to be precise, it can not be confused with the elevator, but also can not carry people, because this simple freight elevator is not equipped with safety devices, such as the table protection is a guardrail, there is no car for carrying people, the operation buttons are on the floor, there is no control on the table, etc. Therefore, it is strictly forbidden to carry people on the lift and freight elevator. However, the hydraulic lift freight elevator can fully meet the up and down transportation of goods, and the lifting height of the general simple freight elevator is generally kept within 20 meters, because with the rise of height, the installation cost of the property will also increase, and without the safety device, its safety will also decline with the rise of the height of the simple freight elevator.

Does the hydraulic lift freight elevator belong to special equipment?

Hello, dear, happy to answer your <>

Answer: Hydraulic lift freight elevator does not belong to special equipment.

Hydraulic freight elevators are not considered special equipment. Hydraulic lift freight elevator belongs to the category of lifting work platform, in 2014 the country issued a new special equipment catalog, the elevator was simplified, only the simple lift and construction lift were retained, the lifting platform was deleted, the hydraulic lift freight elevator no longer belongs to the special equipment, no longer belongs to the scope of special equipment safety supervision, no need to report for inspection. Hydraulic lift freight elevator belongs to the hydraulic lift freight elevator is also called material hoist, to be precise, it can not be confused with the elevator, but also can not carry people, because this simple freight elevator is not equipped with safety devices, such as the table protection is a guardrail, there is no car for carrying people, the operation buttons are on the floor, there is no control on the table, etc.

Therefore, it is strictly forbidden to carry people on the lift and freight elevator. However, the hydraulic lift freight elevator can fully meet the up and down transportation of goods, and the lifting height of the general simple freight elevator is generally kept within 20 meters, because with the rise of height, the installation cost of the property will also increase, and without the safety device, its safety will also decline with the rise of the height of the simple freight elevator.

Recently, many netizens often search for the word home elevator, many people do not know what a home elevator is, what are the types of home elevators, today I will briefly introduce you to the types of home elevators, let's take a look.

According to the use, it can be divided into three types: electrical, hydraulic and manual.

Electric type lifts.

1. The common one is the home elevator, which is often used in duplexes or villas, and is located indoors.

2. Special elevators for the disabled.

Artificial household elevators.

1. The attic elevator is generally used to connect the storage layer or connect the attic of Huidu.

2. Aluminum alloy slub ladder is mostly used for repairing houses, repairing trees and other climbing use, which can be telescopic and lifted, buckled, and has high strength.

3. Herringbone aluminum alloy elevator, which belongs to the household elevator is a common elevator, which is mostly used for installing chandeliers, cleaning ceilings, painting walls, and home decoration before nuclear lights.

4. Insulated elevators, mostly used for wiring with weak points such as household circuits and waterways, with insulation function.

Household elevators are basically the above, basically electricity and artificial, hydraulic elevators are basically engineering elevators, family generalization is rarely used, here will not be introduced one by one, friends who want to know can learn through other channels. Hope the above information is helpful to you.

<> "Elevators are divided according to their use and driving mode

1. According to the use, it is divided into passenger elevators, freight elevators, medical elevators, sundries elevators, tourist elevators, vehicle-mounted elevators, ship elevators, construction elevators and some special elevators.

2. According to the driving mode, it is divided into AC lifts, DC lifts, hydraulic lifts, rack and pinion lifts, and screw lifts.

What problems should be paid attention to in the daily use of various elevators.

1. When we use the elevator, we can't overload. If it is overloaded, the elevator will sound an alarm, and someone needs to leave at this point for the elevator to go up and down normally. The elevator is regularly maintained, and professionals can be asked to inspect and maintain the elevator.

If the elevator is used too frequently, it will cause a certain amount of wear and tear, so it must be maintained regularly in order to use it normally.

2. If the elevator door is about to close, we can't rush into the elevator directly. When the elevator doors are closed, I can't get one foot in the elevator and one foot out of the elevator. At this time, the elevator door will be damaged, and our body will also be damaged.

And the emergency button of the elevator cannot be pressed casually. The panic button can only be pressed in the event of an accident in the elevator. If the elevator is in normal use, it is impossible to press this button.

3. When taking the elevator, if the elevator door switch button does not respond, it means that the elevator is faulty. At this time, you can't drive, and you need to contact the maintenance personnel in time for maintenance. Before taking the elevator, if there is a stop maintenance sign on the door, you can't take the elevator at this time, because the elevator can't work normally during maintenance.

The first category: gantry wire rope traction villa elevator Since the advent of the elevator driven by electricity in 1889, the wire rope traction elevator has experienced 130 years of development, the technology is mature and stable, the main engine generally adopts permanent magnet synchronous gearless traction machine, equipped with VVVF control Qiaoyu drive integrated elevator control system, to ensure the safety and stability of the elevator. It adopts the car system of gantry structure, so that the elevator suspension point, the center of gravity of the elevator, and the center of the guide rail are integrated into one, and it is equipped with a double-layer car bottom with a shock absorption system, so that the elevator operation has an excellent sense of comfort.

The rated power of the villa elevator equipment with a load of 400kg is only about 1kw, and the actual power consumption of a villa elevator is equivalent to the power consumption of a TV. This series of elevators is currently the mainstream product in the villa electric filial piety roller ladder market, accounting for about two-thirds of the market share, and is the preferred product for villa elevators.

The second category: steel belt traction villa elevator In 2000, OTIS Elevator announced the launch of the Gen elevator system, which used flat steel belt technology to replace the steel cable to lift the elevator car for the first time. However, due to patent protection issues, domestic steel belt structures have only been introduced to the market in the past two years.

Because the structure has certain advantages in the hoistway space, for example, the same hoistway width, the use of steel belt structure can increase the net width of the car by 5 to 10 cm compared with the wire rope structure, but compared with the traditional wire rope technology, the maturity is slightly lower, the requirements for installation are relatively high, the equipment cost is slightly higher, and the maintenance cost is relatively higher. With the continuous maturity of its product technology, this series of products has a broad space for development in the future.

The third category: backpack rack wire rope traction villa electricity.
