Q:Is it difficult to test tower cranes?
See the ability of individuals, the first ticket 650 yuan graduation card ID card (copy) medical certificate according to 3 inch 3 days learning theory exam two days of practice examination through 15 days notice thank you hope to adopt licensing
Q:What is the torque limiter of the tower crane A: the lift is stopped when the lifting torque is exceeded. B: over gravity
The torque limiter acts as follows: (a)In lifting process, when the weight of the lifting object moves ahead of the trolley when the lever force exceeds the moment limiter, the hook rises, the motor and the trolley forward motor are stopped at the same time, and the utility model has the safety function.
Q:How to choose tower crane in engineering, such as arm length and lifting weight?
How to choose tower crane in engineering:1, according to the general layout plan on the mechanical layout requirements to determine. The tower crane's arm length should be swept to the required area, otherwise the worker's formwork and materials can not be transported vertically. (tower crane is the main tool to solve vertical transportation, and auxiliary tools are derricks and double cage elevators)2. After a project has been obtained, it is important to design the layout plan of the field machinery at first. It determines the position of the tower crane and uses several tower cranes, etc. it also conforms to the requirements of economic rationality.3, we should take into account the location of the tower crane, but also take into account the length of the tower crane, but also to meet the requirements of the site construction schedule.
Q:What are the four major moving mechanisms of a tower crane?
Tower crane refers to the fuselage for the tower frame, can walk along the track, a crane equipped with rotary arm. 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.
Q:What is an attached tower crane?
Its weight is 5 ~ 100kN, lifting radius of 3 ~ 35m (trolley), the lifting height is 160m, the maximum lifting torque of 1600kN - m, each with high 2.5m, the QT4 - 10 type crane lifting system comprises a lifting sleeve frame, long stroke hydraulic jack, bearing seat, lifting beam and a positioning pin. The cylinder block of the hydraulic jack is installed on the support seat at the bottom of the tower, and the lifting process can be divided into five steps.
Q:What is the inspection certificate for tower cranes?
Inspection certificate of tower crane must have two certificates:1, the manufacturer issued its own "product quality certificate"2. The product quality supervision and inspection certificate issued by the Technical Supervision Bureau
Q:What is the scrap standard of tower crane hook?
The hook shall be scrapped at any time in the following circumstances:Crackle;The wear of the dangerous section is 10% of the original size;The opening ratio is increased by 10% than the original size;The twist of the hook is over 10 degrees;The dangerous section of the hook or the neck of the hook produces plastic deformation;The hook thread is corroded;When the hook bushing is worn at 50% of the original size, the bushing shall be replaced;The mandrel shall be replaced when the hook mandrel is worn at 5% of the original size.
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 does tower crane 400tm mean?
Lifting torque of 400 tons. Meters, also known as 4000KN/m, refers to the QTZ400 tower crane, the general maximum lifting capacity of 25 tons, big arm 70 meters, the most front-end hanging 5.2 tons, independent height of about 70 meters. Normally we say QTZ40 tower crane is lifting torque of 40 tons. Meters, 400KN/m.
Q:Tower crane 5610 why call QTZ63 tower crane, 5613 call QTZ806015, call QTZ100
The name of QTZ is the former mechanical standard, Q refers to the crane, T refers to the tower, Z is to indicate the self lifting, and the latter figure represents the nominal torque, the unit is T.M (the standard unit is KN.m)The type of "QTZ63" indicates the hoisting tower crane with nominal lifting torque up to 630KN.m;The type of "QTZ80" indicates the hoisting tower crane with nominal lifting torque up to 800KN.m;
