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.
Q:Tower crane (tower crane)
In the form of the structure for the tower type, flat type and movable arm type. The model can be divided into QTZ63 suspension, QTZ80 crane, QTZ125 crane, QTZ crane, 315 crane and so on according to the moment division. Now used to arm length + tip weight of the way named, for example, 5513, that is, the longest length of 55 meters arm, the tip of the largest weight of 1.3 tons.
Q:What is the torque limiter of the tower crane A: the lift is stopped when the lifting torque is exceeded. B: over gravity
The torque limiter acts as follows: (a)In lifting process, when the weight of the lifting object moves ahead of the trolley when the lever force exceeds the moment limiter, the hook rises, the motor and the trolley forward motor are stopped at the same time, and the utility model has the safety function.
Q:What special operators should be equipped for the installation and disassembly of tower cranes?
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:What's the difference between QTZ63 and qtz630, isn't it the same kind of tower crane?
It's the same kind of tower crane, but it's only a unit of rated lifting torque. The former unit is 63 tons. M, the latter is 630 kn m. According to the latest national standard "tower crane", GB/T5031-2008 and QTZ63 are written correctly.
Q:Is it difficult to test tower cranes?
See the ability of individuals, the first ticket 650 yuan graduation card ID card (copy) medical certificate according to 3 inch 3 days learning theory exam two days of practice examination through 15 days notice thank you hope to adopt licensing
Q:When the tower crane foundation is found, what should be discontinued?
The settlement, inclination and cracking of tower crane foundation can affect the stability of tower crane and should be stopped
Q:Tower cranes should stop working when the wind speed is greater than the magnitude.
Rules for safety regulation of tower crane,The installation of tower crane is strictly prohibited at grade 4 or above
Q:Can the attached arm of the tower crane be welded?
The attached arm of a tower crane can not be welded and can only be bolted.Adhesion calculation of tower craneTower crane attachment (anchor) device structure, internal force and installation requirements in the use of narrative instructions so in the tower crane installation and use, the use of units can be executed according to the requirements, do not need to calculate, only when the tower crane installation position to the building from the over manual provisions, to increase attached rod (Zhi Chenggan) two, spacing or attached rod connected with a building when changing to attached calculation.
Q:How many meters is the tower crane installed on the edge of the deep foundation pit?
Tower crane foundation, if set up in the foundation pit, the foundation is to pile other, general tower crane is to support the wall.Therefore, how far away from the foundation pit is determined by the distance from the retaining wall.According to the industry standard "technical specification for concrete foundation of tower crane tower crane foundation installation" (JGJ/T187-2009), the installation of tower crane foundation concrete should reach more than 80% of design strength, the tower crane foundation concrete design strength should reach 100%.
