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:Tower crane technical condition GB/T 9462-1999 has been cancelled? If so, what is the new standard?
Standard number: GB/T 5031-2008Standard Name: Tower CraneStandard status: currentAlternatives: instead of GB/T 17806-1999; GB/T 17807-1999; GB/T 5031-1994; GB/T 9462-1999This standard specifies the nomenclature, classification and identification, technical requirements, test methods, inspection rules, information identification, packaging, transportation and storage, installation and climbing, and inspection of tower cranes.
Q:The role of slewing limiter in tower cranes is limited
The function of the rotary limiter is to restrict the large arm to stop at a certain setting. Protect from turning to dangerous range so as to avoid collision and other dangerous accidents!The function of the amplitude limiter is to restrict the car to come out or return somewhere to stop and protect the car from or within certain dangerous range.The hook safety device is to prevent the wire rope from falling out of the big hook, so as to avoid falling and other dangerous events!
Q:Under what circumstances does a tower crane require third party testing?
New installation, demolition, close, major transformation, the use of site work committee, the use of factories to the Technical Supervision Bureau
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 distinguish self lifting tower crane with counterweight and lifting tower crane without counterweight
2 the tower crane without counterweight is mainly the city fast loading tower crane. It is characterized by the absence of balance arm, and it is impossible to have counterweightThe layman can not tell the can see the appearance, there are long steel structure before and after the weight of the tower body, and no weight of the tower body with only one steel structure (i.e. jib crane, structure)
Q:What are the lifting moment requirements for tower cranes?
2 tower cranes (tower crane) referred to as tower cranes, also known as tower cranes, originated in Western europe. A revolving crane mounted on top of a tall tower. 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. 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..Has a good safety device
Q:Are tower cranes the same as tower cranes?
Tomato, you tomato, potatoes, you potatoTalent exchange of tower crane and tower crane
Q:What windproof devices should be set up for crane work?
Safety protection device and function of crane1. overload limiterIt is a safety guard for cranes to prevent overload, also called a weight limiter. The safety function of the utility model is that when the crane load exceeds the rated value, the lifting action is stopped, so as to avoid overloading. Overload limiters are widely used in bridge type cranes and elevators. Some boom type cranes (such as tower cranes and gantry cranes) use the overload limiter and the torque limiter together. Overload limiter has mechanical, electronic and many types.(1): mechanical drive ram through a lever and a spring cam, etc., when overloaded, hit the switch control rod and the lifting action phase, cut off the power source of hoisting mechanism, control the lifting mechanism to suspend operations.(2) electronic: composed of a sensor, an operational amplifier, to control the actuator and load indicator, display, control and alarm and other security functions in a body. When the crane is loaded, the sensor on the load bearing component is deformed, and the load weight is converted into an electric signal, and the value of the load is indicated by operation amplification. When the load exceeds the rated load, the power source of the lifting mechanism is cut off so that the lifting action of the lifting mechanism can not be realized.
Q:What are the basic parameters of a tower crane?
The basic parameters of a tower crane include the length of the crane itself, the weight of the crane as well as the weight of the counterweight! Tower crane lifting mechanism; slewing mechanism; luffing mechanism; motor power;...
