Product Description:

Brief Description:


Tower crane 4808 is used to lift building material such as concrete, steel bars vertically and horizonally.

All tower cranes consist of the same basic parts:

1. The base is bolted to a large concrete pad that supports the crane.

2. The base connects to the mast (or tower), which gives the tower crane its height.

3. Attached to the top of the mast is the slewing unit (large ring-gear and motor) that allows the

crane to rotate.

4. Attached to the slewing unit is the jib (or boom), the machinery arm, the counterweights

 and, the Operators cabin

Q:How do tower cranes rise?
The weight and concrete foundation shall be made in advance and marked, and the ground ground endurance shall be no less than 20T per square meter. The chassis and standard sections are then assembled on this basis. The standard section of tower crane is the main part of the main part of tower crane. It is also the main role of heightening the height of tower crane". In the construction process, tower crane accompanied by the rise of buildings, naturally need to heighten. When the tower is hoisted, the upper frame is raised upwards with the jack up, so that there is a space between the tower body and the frame, and the standard section of the tower body is installed in the space. In this way, the purpose of the tower crane is realized.
Q:What should be included in the disassembly plan of the tower crane?
- 3 - tower crane demolition special program should include the following1. General situation of engineering;2, the tower crane position of the plane and elevation;3. Disassembly order;4, unit weight and hanging point position;5, remove the auxiliary equipment types, performance and arrangement position;6, the power set;7, the construction personnel configuration;8. Rigging and special tools;9, major sources of risk and safety technical measures;10, emergency plans, etc..Note: (1) the special construction plan for the installation and disassembly of tower cranes shall be examined and approved by the units, technology, safety, equipment and other departments, and shall be implemented after approval by the supervisor.(2) the contents and requirements of the special construction scheme for tower crane installation;Compiled from the "building construction tower crane installation, use and disassembly safety technical regulations" JGJ196-2010, please refer to the implementation. Attached: 1, Zhifu Wanda Plaza Tower Crane installation program 2, Muping District Cultural Center project PT7528 tower crane demolition program
Q:When building tall buildings, where is the bottom of the tower crane installed?
It's just a little bit needed, and you're right!! As long as the requirements to ensure verticality, no problemBuilding technical requirements, such as Perpendicularity Error of not more than 3 millimeters per 100 meters, can be guaranteed by the building.
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;
Q:The rated lifting capacity of a tower crane refers to what is allowed and what is allowed to be divided by the crane
The total quality of the crane rated liftingweightincludes the lifting load and the hook and rope a simplified example, such as the rated lifting weight of 100 tons, the quality of the hook and spreader for 5 tons, the actual quality of the goods can lift 95 tons.
Q:What is the function of the balance valve in the hydraulic jacking system of tower crane?
The function of the balance valve is to maintain the balance of the oil pressure, the hydraulic oil delivery flow is stable, so that the tower crane jacket and the upper part of the lift, disassembly, standard time, lift and smooth.
Q:What are the necessary safety devices on a tower crane?
(6) lightning protection and anti electromagnetic wave induction device;For the crane whose hinge height is over 50m, the lightning arrester shall be installed according to the actual situation and the electromagnetic interference shall be taken.(7) tower crane shall install limit torque coupling in order to prevent slewing overload(8) anti stripping device prevents the rope from working position(9) the device prevents the rope from breaking and the trolley is free to slide(10) the car prevents the broken axle device, prevents the trolley wheel to fall off the axle, then falls(11) each part of the brake is a working device and a safety device
Q:Notice of tower crane
Please refer to the technical regulations for the safety of installation, disassembly and use of tower cranes in construction;The following is copy:3 installation of tower cranes3.1 conditions for installation of tower cranes3.1.1 tower crane installation unit must have the construction administrative departments issued the contracted professional qualification and heavy equipment installation engineering construction enterprises safety production license. Tower crane installation units must be engaged in the installation of tower cranes within the scope of qualification permit.In addition to the professional and technical personnel who have the qualification standard, the installation units of 3.1.2 tower cranes shall also have professional personnel who are in line with the project. The person in charge of the project, the project manager and the full-time safety management personnel shall have the certificate of safety production inspection. Tower cranes, installers, electricians, drivers, signal engineers, cable operators should have special construction operation qualification certificates.3.1.3 construction units shall sign professional contract for installation engineering with the installation units, and make clear the responsibility of both sides for safety in production. In case of general contracting of construction, it shall be signed by the general contractor and the installation unit.
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:What type of tower crane does not include tower crane in variable amplitude mode?
Tower crane, tower crane.Tower crane according to its different types, there are the following classification methods.(1) divided by structure type of fixed tower crane by connecting a fixed tower in the foundation or structure, tower crane lifting operation.
