Product Description:

1、Survey
Thank you for choosing the product of Huaxia Group. Please read the Brief Introduction carefully to know the tower crane well.
The tower crane is a hydraulic tower crane with swing top, horizontal jib and mobile trolley. It has the hoisting moment for 760Kn.m;the maximum hoisting load of 6t and the maximum working radius of 50m.The hoisting height of anchoring tower crane is 40m and that of climbing tower crane is 140m.
The tower crane has ingenious design, beautiful shape and simple structure .It is easy to operate and maintain, and is safe and at a reasonable price .It is an ideal construction machines for construction enterprises. It has hoisting mechanism, swing mechanism, top-rising mechanism and radius mechanism, which can work individually or cooperatively to make a high efficiency. The top-rising mechanism is used to raise or lower tower. The hoisting mechanism has 3-speed electronic motor respectively for high, medium and slow hoisting speeds. It has flexible swing mechanism and radius mechanism and slewing mechanism for vertical and /or horizontal transportation of building materials in one time.
The tower crane has complete and sensitive protection devices such as hoisting weight limiter, hoisting moment limiter, hoisting height limiter, radius limiter and swing limiter to ensure of regular operation. It also has rest platform, guardrail and other protection devices. Driver’s cab is at a side of rib and has big space and wide visual field.
The tower crane has excellent performance and is suitable for hoisting in short civil or industrial buildings or loading or unloading in ports or goods yards
The products of Huaxia Group are your best choices of construction machines

Sandhills are much larger than even the largest Egret.which is the Great White, the smallest is the Little or Cattle Egret. All this information can be found by looking into search both species,
Q:How did they get that crane on the top of the Deutsche Bank bldg here by the WTC in NY?
Probably a climbing crane. You build a scaffold with your crane, then climb the scaffold with the crane, anchor, then take the scaffold apart re-assemble it above your current position. Repeat until top of building is reached.
Q:How much height should tower crane work at M?
Try to ensure that the tower crane in the wind is too large to be free of rotation. The safe distance between the rear arm of tower crane and adjacent buildings shall be no less than 50cm. The safe distance between tower crane and power line meets the requirement.
Q:Are tower cranes the same as tower cranes?
Tomato, you tomato, potatoes, you potatoTalent exchange of tower crane and tower crane
Q:I have so many crane flies this spring. Why?
cranes leave their habitat because the first reason was the climate , second its mating season and lastly scarcity of food in their habitat during winter .
Q:How to calculate the pouring and maintenance of tower crane concrete in valuation?
Calculated according to actual concrete quantity. According to the design plan of the visa and construction organization.
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: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.
