Q:What does the lifting mechanism mean in a tower crane?
Magnification, in simple terms, refers to several ropes through the hookIf it is one in and out of two wire rope, that is two magnificationSimilarly, two into two out is four magnification
Q:What are the special operators of tower cranes?
Specific include construction lifting signal division, cable construction, lifting machinery, tower crane driver (T), construction crane, tower crane installation, demolition worker (T), and height job basket, installation, demolition workers.
Q:How to improve the stability of tower crane
Phosphating coating of steel wire rope, give priority to the use of manganese or zinc manganese phosphating, and smooth steel wire rope production process comparison, just add the last bonderizing process, steel wire, wear resistance and corrosion resistance is greatly improved, the use of the wire without direct phosphating cold twisted steel wire rope.
Q:Is it difficult to test tower cranes?
A tower crane installation scheme, 1, compilation basis, project overview, working environment, 2 workers and 3 endurance calculation and installation equipment for 4, installation procedures, methods and requirements for 5, commissioning record 6, two safety technical measures, safety technical disclosure, three installation foundation concrete test report of four, the tower crane installation and acceptance of table five, safety supervision station issued a permit for six, seven, demolition demolition project safety technical clarificaiton tower crane installation scheme project name: preparation: position (title): Approval: job (title): the construction unit: tower crane installation demolition project, the preparatory work before construction: 1. The tower crane installation position, according to the effective range of the construction requirements, site conditions and the role of tower crane, convenient installation and disassembly, the tower crane configuration in 17 axis to 18 Between the axis, away from the outer wall of 5 meters, with 11 standard section. 2, the basis of the principle, the use of concrete foundation, strictly according to random basis drawing. 3, the examination of concrete pressure report, tower foundation has been completed by design and construction, the safety group acceptance, the basic test block delivery, after the test pressure qualified, must be installed. 4. The installation site is level and the channel is repaired. 5, transport parts admission
Q:What are the safety devices in a tower crane?
1 torque limiter. There are two kinds of mechanical electronic.2 weight limiter. There are two kinds of mechanical and electronic.3, lifting limit device.4, slewing limit device.5, amplitude limiter.6, car anti break shaft device.7, the car anti broken rope device.8, jacking up anti stripping device.9, the collision lights.10, luffing tower crane luffing speed protection.11, walking crane limit limiter.12, all kinds of warning signs.
Q:Operation points of tower crane (tower crane)?
Slewing bearing: tower crane is one of the most critical components, mainly to bear overturning moment and vertical load. After the failure, the demolition and replacement is extremely difficult, loss of large, so you have to check carefully to do maintenance, each 200H must be a senior grease lubrication from the rotary bearing surface, until now exudation. Slewing bearing adopts high strength bolt connection, if the pretension is not enough, or long-term operation, do not check, not fastening, will cause loose. If the individual bolts loose, will cause the remaining bolts overload, the consequences will be disastrous. The luffing mechanism only moves horizontally, the load is light and the line speed is not high, so it should be easy to master and operate. However, the amplitude involves the change of the lifting torque, and if there is no stopping in time, there will be the possibility of over torque. Therefore, the main requirement of variable amplitude operation is stationary parking and accurate positioning. The tower crane is of great height and the hanger is hung longer, so it is easy to swing the hanger when it is running. This is an objective phenomenon. What is called stabilization hook operation is how to make the swinging hook stop quickly, or how to make the hook move with the movement of the crane as soon as possible, and minimize the operation of the swing. The operation of stabilization hook is the skill that the driver should master.
Q:What are the components of a tower crane? What are its main technical parameters? What is lifting torque?
2 tower cranes (tower crane) referred to as tower cranes, also known as tower cranes, originated in Western europe. A revolving crane mounted on top of a tall tower. The working space is large, mainly used for the vertical and horizontal transportation of materials and the installation of building components during the building construction. It consists of three parts: metal structure, working mechanism and electrical system. The metal structure includes the tower, the boom and the base. The working mechanism has four parts, lifting, luffing, turning and walking. The electrical system consists of motors, controllers, power distribution cabinets, connecting lines, signals and lighting devices, etc..Has a good safety device 3, tower crane, such as lifting weight limiter, amplitude limiter, height limiter and load torque limiter limiting device, and travel limit switchestower lights wind instrument, wind clip rail device ladders athletic supporter circlewalkways and railings. The driver's cab is comfortable, easy to operate, with good vision and perfect communication facilities.
Q:How to build a tower crane?
4, combination and installation with the boom, hung with arm pull rod.5, the assembly and installation of crane. This boom just installed in the rotary device, the other end is able to lift and hang rod, in accordance with the installation instructions.The power supply auxiliary hoist with 6, switch on the tower cap following installation, the installation of counterweight boom hoist with the.
Q:Tower crane; command; gesture
8. the hook falls slightly: the arm extends to the side, front and bottom, with the angle of the body about 30 degrees, palm down, with the wrist as the axis, repeatedly swinging downward palm.9. hook horizontal move slightly: small arm toward the side of the natural extension, fingers together, palms outward, in the direction of the load should be running, repeat the slow horizontal movement.10., micro range: double arm bent, extended to one side, five fingers straight, palms relative, and the distance between the load and the distance to move.11. directions of landing: five fingers unbend, point out the position where the load should fall.12. stop: small arm horizontally placed in front of the chest, fingers outstretched, palms down, horizontal swing to the side.13. emergency stop: two small arm level placed in his fingers outstretched, palms downwards, while waving to the level of both sides.14. end of work: stretch your hands and fingers and cross over at the front of your forehead.
Q:How to fix the cable on the tower of QTZ125 type tower crane?
segments can be fixed after solving this problem, usually with plastic copper (with insulating layer) and insulator is fixed on the tower body section,
