A: Normally, as for the main force bearing steel structure, Q345B is adopted; as for the assistance force bearing steel structure Q235B is adopted. All of the raw material is outsourced from qualified steel factory in China.

 

Q: What about our  tower crane  warranty?

A: Usually there is one-year quality warranty including main electronic parts (not including consumable parts). There are consumable spare parts together with whole machine and normally they are enough for one year.

Q:Tower crane, this model inside each letter number represents what meaning, ask the great God to inform.TCT7527-20, TC6015A-10E
Two, weight: rated lifting weight and maximum weight. The maximum rated lifting weight refers to the biggest boom in quality to allow the minimum amplitude of the tower crane, is one of the main technical parameters of the tower crane. Three, lifting...
Q:What are the safety devices for tower cranes?
Safety device for tower crane(1) lifting moment limiter, tower crane in lifting objects, the lifting radius and weight of the crane product is a constant number. According to this principle, a lifting torque limiter has been developed, the main function is to prevent overloading of the safety devices. The moment limiter only acts as a protection against the overload torque in the vertical vertical plane of the tower crane arm, and can not protect the tilting accidents caused by oblique hanging, wind load, rail inclination or collapse, etc..(2) weight limiter weight limiter's role is to protect the goods lifting weight does not exceed the maximum allowable weight of tower crane, tower crane is used to prevent the load exceeds the maximum rated load, avoid mechanical damage accident.
Q:Tower crane and tower crane 5
Tower crane is tower crane. It depends on where you are and what you transport. These are the keys.
Q:What are the qualifications for site installation and acceptance of tower cranes and construction lifts?
and their own preparation program, the use of side with security records, often do this, all know!
Q:When the tower crane is installed in the fertilizer tank,
There is no standard in the tower crane foundation and building foundation, there is no such provisions.In fact, you can do whatever you can. The only factor that can be said is the Design Institute, to see if they agree.Design Institute to consider this problem, generally disagree, you let the two based on the surface flat, because there is a stress concentration problems. It's like a pebble under your mattress. So, in general they will demand based on the surface in the construction of tower crane foundation floor, the middle 30-50cm gap with soil pad.Of course, no matter which of these two methods you have to use the back belt to enclose the tower crane foundation.
Q:What is the inspection certificate for tower cranes?
Inspection certificate of tower crane must have two certificates:1, the manufacturer issued its own "product quality certificate"2. The product quality supervision and inspection certificate issued by the Technical Supervision Bureau
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.
Q:How much height should tower crane work at M?
Try to ensure that the tower crane in the wind is too large to be free of rotation. The safe distance between the rear arm of tower crane and adjacent buildings shall be no less than 50cm. The safe distance between tower crane and power line meets the requirement.
Q:What does tower crane 400tm mean?
Lifting torque of 400 tons. Meters, also known as 4000KN/m, refers to the QTZ400 tower crane, the general maximum lifting capacity of 25 tons, big arm 70 meters, the most front-end hanging 5.2 tons, independent height of about 70 meters. Normally we say QTZ40 tower crane is lifting torque of 40 tons. Meters, 400KN/m.
