Q:What is the minimum radius of a tower crane?
Luffing jib crane luffing mechanism to control the lifting radius, which is lifting and landing boom.At the minimum radius, the boom is angled to the vertical. The higher the rise, the larger the angle, the smaller the radius.I wonder if it's this angle? Hope to be of help to you,
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:How many tons are tower cranes QTZ125?
The performance parameters and technical indexes of this machine are up to or better than the national standard. The maximum working range is 65m, height is 50m independent, attached type lifting height up to 180m, the maximum working range of 65 meters, the rated lifting torque 1200kN - M.The machine parameters is advanced, reliable performance, beautiful appearance, good quality, simple and practical structure, equipped with advanced safety device, convenient maintenance, safe use, reasonable price, is the ideal construction machine for construction enterprises.
Q:How about the installation and disassembly of the tower cranes?
Authorized by the national security inspection department, the local special operations training school or the technical quality supervision bureau, after the study, assessment, qualification and graduation permit, will give you special operations installation, removal operation certificate.
Q:In the case of tower crane operation, the operation should be stopped
In case of six or more gales, heavy rain, heavy fog, heavy snow or tower crane, you should stop working
Q:Tower cranes should stop working when the wind speed is greater than the magnitude.
Tower crane work is strictly prohibited at grade 4 or above
Q:Tower crane attached concrete pump can be? Are there any state regulations?
Yes, but consider the direction of force. ZOOMLION began production machine.
Q:How to choose tower crane in engineering, such as arm length and lifting weight?
First of all, your engineering structure is reinforced concrete Or steel? What's the weight of the lift? The lifting capacity of tower cranes should meet the needs. Generally speaking, steel structure hoisting, tower crane of the largest lifting weight and gravity moment should be large; hanging steel reinforcement of a smaller can.Secondly, the boom length should be covering the scope of construction (can also be arranged to meet several sets of crane lifting coverage). But in the 360 level luffing jib range, can not have obstacles (other cranes and buildings), and the boom and the distance between them (below) should be not less than 2m.Third, in the construction project is relatively high, the site is relatively small, you can mount the internal climbing tower crane. Building covers a large area, sometimes one can solve the problem. Of course, it is more troublesome to disassemble and lift inside, but the standard section used is less and the cost can be lower.
Q:How to change the mechanical property unit of crane (tower crane)?
Measures for the record and registration of construction hoisting machineryArticle 1 These measures are formulated in accordance with the provisions on the supervision and administration of the safety of construction cranes' machinery (Order No. 166th of the Ministry of construction) in order to strengthen the management of the record and registration of construction cranes.The construction and registration of the hoisting machinery as mentioned in the present Measures shall include the registration of the lifting machinery, the installation (disassembly), the notification and the use of the registration of the second.Third construction departments of the people's governments at or above the county level may use the computer information management system to handle the registration and registration of construction hoisting machinery, and establish a database.The construction administrative department of the local people's government at or above the county level shall provide the registration and registration and inquiry service of the building hoisting machinery within its administrative area.Article fourth rental, installation and use of units shall be submitted in accordance with the provisions of the lifting of construction machinery registration information, and the authenticity of the information provided by the responsible.The construction administrative department of the local people's government at or above the county level shall establish a system for the examination and registration of the hoisting machinery.Fifth construction machinery rental units or purchase building lifting units (hereinafter referred to as the "property units") in the construction machinery rental for the first time or before the installation, should be registered at the competent construction Department of the local people's governments at or above the county level to the unit of business (hereinafter referred to as the "equipment registration authority") for the record.
Q:Tower crane four limit, two insurance, two insurance what is that?
Refers to the air switch and the electric leakage protector in the electric tray.
