Q:Tower crane, this model inside each letter number represents what meaning, ask the great God to inform.TCT7527-20, TC6015A-10E
The basic parameters of the tower crane: a working range: refers to the center of rotation of the lifting hook up center and tower crane horizontal distance. 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 special operators should be equipped for the installation and disassembly of tower cranes?
According to the requirements of the 2.0.3 specification: tower crane tower crane installation and disassembly operation should be equipped with the following: 1, hold a qualified safety assessment certificate of the project and responsible for the safety of people and machinery management personnel; 2, with construction qualification certificates for special operations of the construction hoisting machinery installation and disassembly, lifting work, special operation signal heavy drivers, riggers and other operations personnel. And an electrician.
Q:Tower crane body standard section connection bolt screw upward or downward, why?.
Usually it is worn from top to bottom, so that the nut is loose and the bolt will not fall directly
Q:What kind of equipment must be installed on luffing trolley of horizontal luffing tower crane?
The car must have a support wheel to prevent the trolley from hanging in the middle.
Q:Climbing process of an internal climbing tower crane
Climbing tower crane, usually installed in the elevator shaft building or ad hoc Bay, also can be installed in the cylinder structure, by means of a climbing mechanism increases with the structure increases, generally every building 3~8m, crane climbing a tower, its height is only 20m left and right, lifting height with construction height and.
Q:The earthing resistance of tower crane shall not be greater than that of the tower crane
The lightning resistance of tower crane (tower crane) on the construction site shall be no more than 4 ohms.I. tower crane GB/T 5031--20085.5.5.9 lightning protectionIn order to avoid lightning stroke, the main structure of the tower crane, the motor frame and all the electrical equipment metal shell, wire metal protection tube should be reliable grounding, and its grounding resistance should be no more than 4 ohms. When multiple repetitive earthing is adopted, the grounding resistance shall be no more than 10 ohms.Two. Safety regulations for tower cranes GB 5144 - 20068.1.3 tower crane metal structure, track, all electrical equipment metal shell, metal line pipe, safety lighting transformer, low voltage side should be reliable grounding, grounding resistance is not more than 4 ohms. Repeated earthing resistance is not greater than l0. The selection and installation of the earthing device shall comply with the relevant requirements of the electrical safety.The insulation resistance of the 8.1.7 main circuit and control circuit shall not be less than 0.5M ohm.
Q:How to build a tower crane?
7, the boom of the horizontal installation, setup of counterweight, main hoist installation, installation sequence of these large, there are provisions in the instructions.8 、 install operating room, main cable and control cable. Installation of crane wire rope, hook, lifting the car has been in the assembly of the boom when installed.9, at this time has completed the basic installation, the later self lifting installation, the main work by the tower crane itself equipment and artificial to complete.10 tower crane from basic height to work height.Each type of tower crane has different self lifting mounting methods. In fact, in addition to carrying heavy loads, the installation of a large number of high-strength bolts is a heavy work.11, the above is the general procedure, the actual installation work in strict accordance with the installation instructions. According to historical experience, tower crane installation accidents often occur in some professional installation team.12, the old type of tower crane installation is relatively simple, but also have independent installation, and now the development of automobile crane is not a must, general use of car crane can complete all the installation.
Q:How to improve the stability of tower crane
Increase the overall weight of the base and weight, the tower structure to be strengthened.Crane wire rope is phosphate coated steel wire, galvanized steel wire, stainless steel wire rope, the use of atmospheric environment, patented technology to produce manganese phosphating coating of steel wire rope has the longest lifespan, heavy corrosion environment optimization of hot galvanized wire rope double - phosphating coating.
Q:Tower crane four limit, two insurance, two insurance what is that?
Four limit: torque, ultra high, variable amplitude, walking limit device. Two insurance: hook insurance and reel safety device.
Q:What does a track type tower crane look like? In that case, use?
The rail type multi characteristic tower crane consists of track, door frame, main arm, auxiliary arm, hook and so on. Its features are: A, crane through the door frame (2), supported on a track (1); B, the door frame (2) is provided with a rotary bearing (3); C (3) is arranged on the rotary supporting all kinds of machinery and equipment (4), and balance weight (8); D, the main arm (5) the jib (6) through the bearing cable (7) is installed on the rotary support (3); E, the main arm (5) side arm (6) and Russo (7) can have a variety of length combination; F, a main arm, jib all tube truss structure; G, hook pulley h, equipped with a variety of rate; the torque limiter (10) and amplitude detection device (11); I, operating room in slewing bearing (3); J, self moving use winch is luffing winch main arm, mounted on a rotary support (3).Track type multi characteristic tower crane. The utility model is especially suitable for power construction and hoisting operation. The slewing support on the track type door frame is provided with a main and an auxiliary arm frame, and various variants can be formed through different combinations. Its maximum torque of 3360 tons meters, the maximum lifting capacity of 140 tons, the maximum working range of 60 meters, the maximum rise of 120 meters. The utility model can be carried in the lifting, and the work is smooth and safe. The main and auxiliary arms are all truss structures, light in weight. The electronic torque limiter and other safety devices are adopted, and the 130 meter high machine can be installed by itself. This machine can also be used in petroleum, chemical, metallurgical and other large projects.
