There is a magnification pin on the hook group. When the magnification pin is removed, the pulley will automatically slide to the lifting trolley.
Q:What is the definition of lifting, slewing and luffing of tower cranes?
Rotary is cantilever tower crane tower crane rotary shaft winding;Is the hook shaft distance amplitude change;
Q:What should be included in the disassembly plan of the tower crane?
- 1 -Contents and requirements of special construction plan for tower crane installation1. General situation of Engineering; 2, installation location and elevation plane3. The type, performance and technical parameters of the tower crane selected4,; foundation and attachment device set(1)The foundation of tower crane and the bearing capacity of its foundation shall comply with the product specificationRequirements for books and design drawings. Before installation, the foundation shall be checked and accepted before installation. There should be drainage facilities around the foundation.(2)Attached tower crane is used, the attachment device and set freeThe end height shall comply with the requirements of the product manual. When adhering to a horizontal distance or attachmentThe design calculation and drawing system should be carried out when the spacing is not satisfied with the requirements of the product specificationDrawing and writing relevant instructions shall be examined and approved by the technical leaders of the enterprise or through the originalManufacturer confirmation. Attachment device and component shall be the original manufacturer or by embedded partsEnterprise with corresponding ability to make. Attachment device design, the main structure of the building to support the checking.5, climbing conditions and adhesion node detail;The foundation, anchor and climbing support structure of an internal climbing tower crane shall be used as the foundationAccording to the product manual to provide the design calculation, and the internal climbing tower crane bearing structure checking.6, the main components of the weight lifting and installation position.7, the installation of auxiliary equipment; the type, performance and arrangement position.8. Rigging and special tools9, set the power supply;10, the construction personnel configuration;
Q:Four for crane, two for insurance, two for insurance. What does that mean?
Refers to the air switch and the electric leakage protector in the electric tray.
Q:In what circumstances should a tower crane be demonstrated by an expert?
Circular of the Ministry of housing, urban and rural construction on Issuing the measures for the safety administration of sub hazardous and sub divisional projectsBuilding quality [2009]87 number]Annex twoMore than a certain size of the risk of larger sub sub project scopeI. deep foundation pit engineering......
Q:What should the sub contractor do before the installation of the bridge crane in the workshop?
Baidu search [tower crane tower demolition, lowering section safety technical disclosure]. If it is installed, remove the "two words" to "installation", and other contents are adjusted slightly.
Q:What does "slewing up" and "under rotating" in the slewing form of a tower crane mean?
As for the reasons, the main consideration is the actual needs.
Q:When the tower crane is installed in the fertilizer tank,
There is no standard in the tower crane foundation and building foundation, there is no such provisions.In fact, you can do whatever you can. The only factor that can be said is the Design Institute, to see if they agree.Design Institute to consider this problem, generally disagree, you let the two based on the surface flat, because there is a stress concentration problems. It's like a pebble under your mattress. So, in general they will demand based on the surface in the construction of tower crane foundation floor, the middle 30-50cm gap with soil pad.Of course, no matter which of these two methods you have to use the back belt to enclose the tower crane foundation.
Q:Tower crane demolition safety technical disclosure, how to write?
Baidu search:Tower crane removing and lowering joint safety technical disclosure.
Q:What are the characteristics of a tower crane?
Four, according to the different installation methods of cranes, can be divided into folding transport, self erection of the rapid erection of tower cranes and the need to use the auxiliary machine assembly and disassembly of tower cranes.Can set up their own fast loading crane are small and medium slewing tower crane, mainly used for short duration, low buildings move frequently, the main advantage is to improve work efficiency, save installation cost, save time and labor and material, disadvantage is the complicated structure, large amount of maintenance.A tower crane that needs to be disassembled and assembled by an auxiliary machine is mainly used in middle and high rise buildings, with large working range and large lifting capacity. It is the main type of construction site at present.Five, according to whether the spire structure, can be divided into flat head tower crane and tower tower crane.Tower crane is a new type of tower crane is developed in recent years, its characteristic is the tower cap and the rod part before and after the cancellation in the structure of the original tower crane on the enhanced structural strength of the arm and balance arm, arm and balance arm is directly connected, the utility model has the advantages of:1 、 the whole machine is small in size, easy to install and safe, reduce transportation and storage costs;2, the boom of tolerance and good performance, uniform stress, small damage on the structure and connection part;3, component design can be standardized, modular and interchangeable, reduce equipment idle, improve investment efficiency.It is in the same type of tower crane tower crane head Zhongping slightly higher prices.
