Q:Are there any special requirements for the installation of wall fittings of tower cranes?
The wall pieces should be rigidly connected on the wall of the embedded parts.
Q:Tower crane and tower crane 5
Tower crane, tower crane, also known as tower craneTower crane = tower crane = tower craneThere are many ways of vertical transportation. Construction elevator hoist etc..Tower crane features: large operating space, mainly used in housing construction materials vertical and horizontal transmission and installation of building components.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..
Q:How often should the crane be inspected regularly?
Tower cranes, elevators, mobile cranes 1 times a year, including rubber tyred container gantry crane every 2 years 1; small light lifting equipment, bridge crane, gantry crane, gantry crane, cable crane, crane mast, railway crane, jib crane, mechanical parking equipment every 2 years 1, the crane annual molten metal and hot metal 1.Rules for periodical inspection of lifting machineryArticle 1 These rules are formulated in accordance with the regulations on the supervision of special equipment safety and the regulations on the supervision of crane safety.Article second of the rules from the regular inspection of heavy machinery, is often used in hoisting machinery maintenance unit (hereinafter referred to as the foundation of the self inspection and maintenance), by the State Administration of Quality Supervision Inspection and Quarantine (hereinafter referred to as the State Quality Inspection Administration) special equipment inspection agency approved (hereinafter referred to as the inspection agency) according to the rules, to incorporate the use of registration in the inspection of crane.Article third these rules apply to lifting machinery within the scope stipulated in the regulations on safety supervision of special equipment. All the hoisting machines included in the catalogue of special equipment shall be inspected regularly."No" included in the catalogue of special equipment installation supervision and inspection and the implementation form of hoisting machinery factory, direct delivery unit, for use in pre registration by the local inspection agencies in accordance with the rules of the test items and their contents, requirements and methods for inspection of the equipment before using test (i.e., referred to as the first examination), qualified rear can be used for registration. For the first inspection of hoisting machinery, see Appendix A.
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:What does "automatic tower crane" mean less than 100 tons per metre?
When you are working on this crane, the weight between the weight and the weight to the horizontal distance of the crane Center shall not be greater than 100 tons.For example, if the weight and crane center level distance is 10 meters, the maximum weight is 10 tons; if it is 20 meters, the maximum lifting weight is 5 tons; if it is 40 meters, the maximum lifting weight is 2.5 tons.
Q:How to build a tower crane?
Nowadays, most tower cranes used in construction sites have self lifting function, but they can not leave the coordination of cranes when they are installed.Here's the tower crane installation:1, track laying: few walking tower crane, if the working position is not changed in a stage, rail crane fixtures will be locked.Some tower cranes have no running wheels, and the tower cranes are installed directly on the required basis.2. Install the tower crane chassis parts: installation requirements, installation, and placed in the location of the weight block.3. Install the basic tower, revolving parts and tower cap.Each tower crane has the basic height of the tower installation, the installation height of the rotating device and tower cap, these work is the use of sufficient lifting capacity of the car crane to complete.
Q:What does tower crane jacking up mean?
Jack beam and the lifting sleeve frame is connected with the movable claw beam under the fulcrum can fall in the tower body section on the top step.
Q:What role does the tower crane torque limiter play?
The overload protection of tower crane is protected by two equipment, lifting load limiter and torque limiter. The latter generally in the big arm root 4-5 meters to the front of the large arm, overloading (Chao Liju) work, it is more important, basically, the scope of work is torque limiter plays a protective role. While the former is the weight limiter function in the arm root within 4-5 meters, because the tower crane is a jib type crane, each allowing weight lifting position corresponding to the different (CAB load curve). For example, such as 63KN.M, the big arm root 2 meters lifting, the theory is 23 tons, while the torque limiter is not over, but in fact, the tower crane at early crouched down, so the weight limiter in this work.
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: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.Mobile tower crane: a tower crane with running device and can walk.
