Q:The difference between the derrick and the construction elevator?
You want the picture to still want to explain, the words to go to baidu search all can. The derrick is not to be multiplied by the person, the setting height is not more than 30 meters, now most of the place begin to phase out the use of the derrick, because the safety coefficient is low. The construction elevator can carry cargo, set up a height of 150 meters, and can carry a weight of 1-3 tons
Q:What is the need for the sc200/200 construction elevator cable?
The sc200/200 construction elevator cable line should not be below 120 square. Man's ladder 33KW, 5 * 33 = 165KW The tower is 45KW one, 2 * 45 = 90KW The pressure slag welder is estimated to be 25KW Touch welder 1OKW, 5 * 10 = 50KW Other facilities such as mixer, temporary illumination etc. 30KW Total power: 165 + 90 + 25 + 50 + 30 = 365KW One square cable is 5 minus 7A, 380V is 1KW is equal to 2A. That's 730A 730A divided by 5-7 calculates that the cable line should not be less than 120 square.
Q:Why is the construction elevator open on one side and the other on the other
Open the door, commonly known as the feed door, usually open up, and add weights to both sides. Only if the construction ladder stops at the bottom. If the door is double open, the room must be left with half a door (> 1.3 m) to open the door completely. If it is a single open door that opens up, you can save space in the cage. Double door, namely, two doors, either up or down, the two doors balance weight. It usually arrives on the required floor. There is enough room for double doors.
Q:The maximum allowable deviation of the vertical is the vertical degree when the construction elevator is installed
5 kinds of circumstances. 1: the height of the elevator guide frame is less than 70 meters, and the vertical deviation should not be greater than one in 1000 of the height of the guide frame. (assuming the rail frame is 70 meters high, the deviation cannot be greater than 70mm) 2: the rail frame is greater than 70 meters and is less than 100 meters, and the deviation is less than or equal to 70 mm. 3: the guide frame is larger than 100 meters and is less than 150 meters. The deviation is less than or equal to 90 mm. 4: the guide frame is larger than 150 meters is less than or equal to 200 meters. The deviation is less than or equal to 110 mm. 5: the guide frame is greater than 200 meters, and the deviation is less than 130 mm. This is based on the requirement of 5.2.2.1 from GB10054 to 2005. (it used to be a direct copy.)
Q:What is the meaning of double straps in the construction elevator?
Used for heavy to offset the hoisting cage weight so as to realize energy-saving province electric hoist, by making use of the fixed pulley for heavy gravity into upward traction hanging basket of traction, so as to reduce the drive motor load, achieve energy saving.
Q:How many years does the construction elevator usually use?
Wire rope derrick type: 5 years Gear rack: 8 years After the accident, the person in charge will be unlucky
Q:How many floors do you need to install a construction elevator?
Do not have a regulation, as long as the benefit construction organization, installation does not install construction lift machine all can. It should be explained that the construction elevator has manned and pure cargo.
Q:Is the construction elevator the same as the construction elevator
The construction elevator is the standard name, there are national standards, including the elevator, the people's elevator, the construction elevator is the popular term, the general point is the people's elevator not including the elevator.
Q:There are differences between the construction elevator and the construction elevator
The principle is different, the construction elevator operates in the litter box. The elevators are short for construction elevators, which are very high in the safety and performance of large facilities that can be used on the site. The construction elevator should be a dual-use lifting device.
Q:Do the elevator need to be installed when the main project is in construction
Installation, of course. The general building should be installed at about 10 meters on the 4th floor, or the person will go up and down the time is dangerous, and there will be some materials that can't be carried by the tower, too slowly
