Q:The elevator is banned from using elevators for more than a class of high winds

More than 6 levels of wind are forbidden to be removed and used. More than 4 levels of wind are not allowed to rise, and more than 6 winds are prohibited.

Q:How many people are there for construction workers

At the end of the 20th century, the elevator was powered by the permanent magnet synchronous towing machine. It greatly reduces the space of the machine room, and it has the advantages of low energy consumption, energy efficiency and speed, which has greatly contributed to the development of real estate. Thyssenkrupp elevator company has developed a new type of "multiple lift" that can operate vertically. Take the size of a common car The size of the escalator is quite different: but the total area is required in the national standard. Give you a general calculation The width of the well is the width of the car. Well, the depth of the well = the car depth + 600 (for the reside) The width of the well is the width of the car. Well, the depth of the well = the car's depth + 1200 (for the rear-end). The u-shaped tourist ladder is usually around 1000kg The car is usually about 1300x1800 The steel structure shaft is width between 2200 and 2400, depending on the size of the door. The depth of the structure is about 1500, and the rear wall is empty.

Q:A lift motor is 7.5 KW, and the frequency converter sends current 4.2 A, which has A heating resistance in the converter, and how the charge is calculated when the lift is full. Or consider the power of the converter and the power of the thermal resistance.

Try using the security software. There is a cracked version

Q:How does the construction lift fall without electricity

This is not calculated according to the distance, it is calculated speed, when the anti-pendant achieves the rated speed, the pendant should be held automatically. It can't go on.

Q:The working principle of construction elevator

How the elevator works: The main bearing structure is self-formed system, which is low on construction. It more driven by force, drive devices are installed on the hanging basket, through the gear and rack drive system, the mutual cooperation, so as to realize the rise and fall of the elevator.

Q:The construction of more than many floors must be used for construction elevators

Elevator drivers must be trained in special safety technology, qualified for examination, and will be on duty. Strict drunken work. The driver must be familiar with the performance, construction, maintenance and maintenance of the elevator, and fill in the mechanical resume and the required reports in time. No inflammable, flammable goods and other sundries shall be piled up in the vicinity of 5m in the construction elevator, and no ditch, pits, or groove shall be dug in this area. The floor feed of the elevator should be set up for protection. When the cage is repaired, if the parts are removed and the weight of the ladder is below the weight, the ladder cage must be locked in the rail. It is strictly forbidden to use the shaft of the construction elevator to support the cable line and other items not related to the elevator. A tower crane or other lifting machine that is built on the same site shall be more than 5m above the elevator and should be properly protected against collision. After the construction elevator is installed, it must be checked and approved by the relevant personnel.

Q:Construction elevator positioning should consider which problems

The construction elevator is short for construction. It is an important equipment in high-rise building construction, and construction site accident hazards easily, because it can cause many major accidents, injuries in the inspection should be listed as a key to check the content. Based on past accidents and on-site inspections, we often find topics that we think should be examined in a critical area

Q:What is the height of protecting door protection of construction elevator

Referring to the unified code of construction safety technology of GB 50870-2013, and the construction safety inspection standard JGJ59-2011

Q:How to save the elevator accident

Expert clew Do not take an elevator with no safety check mark. The elevator person is safe to protect the condition, the passenger has no life danger, after the alarm, the patient wait for the person to help. When emergency situations such as earthquake, fire and elevator water are taken, the use of an elevator should not be used and the emergency passage or staircase should be used instead.

Q:What is the meaning of double straps in the construction elevator?

With double cage for heavy, namely SCD200/200 series Is the two cages, each cage has a corresponding weight, the weight up and down in the elevator cage rise to energy conservation and reduce the reaction between the up and down, when you imagine front-rear door principle is about the same
