Q:Detailed parameters of QTZ80 tower crane 50
You're welcomeDesign units are different.Our factory is Langfang Design Institute drawings. May refer to the following.Arms 55 meters long.
Q:What are the special operators of tower cranes?
Specific include construction lifting signal division, cable construction, lifting machinery, tower crane driver (T), construction crane, tower crane installation, demolition worker (T), and height job basket, installation, demolition workers.
Q:What are the safety devices for tower cranes?
(6) the rail clamp is used to clamp the rail, prevent the crane from walking by wind in the strong wind, and cause the tower crane to derail and overturn the accident.(7) the wind meter automatically records the wind speed, and automatically alarms when more than six wind speed is over.(8) the anti stripping device of the steel wire rope is mainly used to prevent the steel wire rope from disengaging from the pulley groove during the transmission process(9) the hook insurance prevents the lifting of the steel wire rope because of the excessive angle or the wrong hook, and causes the lifting wire rope to be broken off and the suspension falling accident.
Q:The rated lifting capacity of a tower crane refers to what is allowed and what is allowed to be divided by the crane
The total quality of the crane rated liftingweightincludes the lifting load and the hook and rope a simplified example, such as the rated lifting weight of 100 tons, the quality of the hook and spreader for 5 tons, the actual quality of the goods can lift 95 tons.
Q:Examples of filling and acceptance forms for tower cranes and examples of filling in.
4 data filled in the requirements of the project, in addition to fill in the above sign, but also need to fill in the corresponding data. Data that needs to be filled in should be separated by "/" or "," and, if necessary, distinguished by text or graphic.
Q:What is the difference between a tower crane QTZ31.5 and a QTZ40?
Lifting moment, arm length, elevation is not the same ah! Specifically, the maximum lifting weight of QTZ315 is 3 tons, the length of the arm is from 38-42 meters, the elevation is 27-28 meters; the maximum QTZ40 is 4 tons; the length of the arm is 42-48 meters; the elevation is 29-32 meters.
Q:What are the parts of a tower crane? What are their main functions?

Q:In order to ensure the stability of tower cranes, generally along the height of the tower and building a number of meters attached
Self lifting tower crane tower 45 meters high to prevail, such as height of over 45 meters, each increased to 10 meters (less than 5 meters, excluding) demolition costs increase 20%, off-site transportation costs increased by 10%.
Q:About tower crane torque limiter with 4 limit switches, each play a role, thank you
The maximum amplitude control: when the weight exceeds or prohibit increase load rate of more than 105% or greater than the maximum amplitude (amplitude limit) output control, allowing the car to be near range by car distance to increase amplitude is prohibited.Minimum range control: when the amplitude is less than the minimum amplitude (amplitude lower limit), the output control allows the car to move to a distant range, i.e., to increase
Q:What is the free height of a tower crane?
The free height of large tower cranes can be up to 100 meters.
