Q:Tower crane 4 how to change the rate of 2 magnification, how to change, say detailed points
There is a magnification pin on the hook group. When the magnification pin is removed, the pulley will automatically slide to the lifting trolley. At this point, the rope will be turned into 2 fold!Some manufacturers produce pulley, also need to be in the car, and then the magnification pulley with pin shaft fixed in the car!
Q:How to build a tower crane?
Nowadays, most tower cranes used in construction sites have self lifting function, but they can not leave the coordination of cranes when they are installed.Here's the tower crane installation:1, track laying: few walking tower crane, if the working position is not changed in a stage, rail crane fixtures will be locked.Some tower cranes have no running wheels, and the tower cranes are installed directly on the required basis.2. Install the tower crane chassis parts: installation requirements, installation, and placed in the location of the weight block.3. Install the basic tower, revolving parts and tower cap.Each tower crane has the basic height of the tower installation, the installation height of the rotating device and tower cap, these work is the use of sufficient lifting capacity of the car crane to complete.
Q:When the tower crane is installed in the fertilizer tank,
Pouring foundation does not increase the foundation safety first
Q:How many meters is the tower crane installed on the edge of the deep foundation pit?
If you set the tower crane foundation in the foundation pit, which is based on another piling, the general is to help the wall of the tower crane (unless your project in the free height under it), so far away from the foundation by the wall distance set.The two tower cranes are all supported by piles and steel lattice columns in the foundation pit. The distance is determined by the distance between the outer edge of the main structure and the supporting wall.
Q:What is the wall radius of a qtz50 tower crane?
The working radius is usually 50 meters. There are also 48, 49 meters. For example, 4810, 4910, and 5010, belong to 50 tons of tower cranes.Qtz50 resolves to:Q: crane;T: Tower type;Z: Jack up;50: lifting torque of 50 tons meters.
Q:What does "slewing up" and "under rotating" in the slewing form of a tower crane mean?
In short, when the tower rotates in the form of a tower, the tower is stationary (ie does not follow the rotation), and the form of the lower turn is the tower will rotate. As for the reasons, the main consideration is the actual needs.
Q:Tower crane (tower crane)
In the form of the structure for the tower type, flat type and movable arm type. The model can be divided into QTZ63 suspension, QTZ80 crane, QTZ125 crane, QTZ crane, 315 crane and so on according to the moment division. Now used to arm length + tip weight of the way named, for example, 5513, that is, the longest length of 55 meters arm, the tip of the largest weight of 1.3 tons.
Q:Tower crane driver simulation exam which website?
The driver of the tower exam is nothing more than the operation and safety of knowledge.
Q:In what circumstances should a tower crane be demonstrated by an expert?
Circular of the Ministry of housing, urban and rural construction on Issuing the measures for the safety administration of sub hazardous and sub divisional projectsBuilding quality [2009]87 number]Annex twoMore than a certain size of the risk of larger sub sub project scopeI. deep foundation pit engineering......
Q:How much more than m of tower crane jib winch point height should be equipped with anemometer
According to the regulations of JGJ196-2010 for the safety and safety of installation, use and disassembly of tower cranes for construction purposes:The use of 4.0.15 tower crane height of more than 30m should be equipped with obstacle lights, jib root hinge height of more than 50m should be equipped with anemometer.
