Q:There is no CAD map attached to embedded parts of tower crane?
4810 as long as 16. The middle spacing is different. It's almost impossible to install
Q:QTZ63 (Q5610) tower crane power, how many power parts, name, model specification, product number, date of appearance
All the details of the equipment are availableAs for power, it depends on the specific configuration of the frequency conversion and non frequency conversion will not be the same
Q:Construction tower crane driver (T) Ben can be used as construction crane driver (S)?
Building crane driver (T); tower crane driverConstruction crane drivers (S); construction elevator drivers; neither is common.
Q:What are the four major moving mechanisms of a tower crane?
Four big bodies of tower crane: lifting, slewing, luffing and walking.
Q:What is the calibration value of a tower crane?
Do you mean the calibration value of crane lifting moment? That should be the product of the maximum magnitude of the tower crane and the corresponding maximum lifting load.
Q:What windproof devices should be set up for crane work?
Safety protection device and function of crane1. overload limiterIt is a safety guard for cranes to prevent overload, also called a weight limiter. The safety function of the utility model is that when the crane load exceeds the rated value, the lifting action is stopped, so as to avoid overloading. Overload limiters are widely used in bridge type cranes and elevators. Some boom type cranes (such as tower cranes and gantry cranes) use the overload limiter and the torque limiter together. Overload limiter has mechanical, electronic and many types.(1): mechanical drive ram through a lever and a spring cam, etc., when overloaded, hit the switch control rod and the lifting action phase, cut off the power source of hoisting mechanism, control the lifting mechanism to suspend operations.(2) electronic: composed of a sensor, an operational amplifier, to control the actuator and load indicator, display, control and alarm and other security functions in a body. When the crane is loaded, the sensor on the load bearing component is deformed, and the load weight is converted into an electric signal, and the value of the load is indicated by operation amplification. When the load exceeds the rated load, the power source of the lifting mechanism is cut off so that the lifting action of the lifting mechanism can not be realized.
Q:Minimum QTZ63 tower crane special electric box open for many A
QTZ63 tower crane with air and leakage protection:Minimum three-phase air switch not less than 100A; at the same time leakage protector is not less than 100A three-phase four wire system leakage protection.Maximum three-phase air switch not greater than 150A; at the same time, leakage protector is not more than 150A of three-phase four wire system leakage protection.
Q:What is a TQ80 tower crane?
A full swing jib crane with a tower type structure, a crane that can travel along the track and is equipped with a full swing arm.
Q:About tower crane torque limiter with 4 limit switches, each play a role, thank you
Hook top point control: when the hook to the high limit, limit action, do not continue to hook!Overload control: when the weight exceeds the overload point or amplitude exceeds the maximum amplitude or the loading rate is more than 105% when the output control, prohibit the hook lifting action and prohibit car distance to allow the car to increase the amplitude, amplitude can be damped near.
Q:When building tall buildings, where is the bottom of the tower crane installed?
The installation of tower cranes is certainly a guaranteeThe installer is dangerous,
