Product Description:

 

echnology is the drive for business development and production equipment the assurance of product quality. In the large-scale concentrated production, the stability and uniformity of product quality plays an essential role. The company constantly improves processing equipment. The automatic assembly line ensured quality stability and maximally reduced adverse effect of personal factor to the product quality. As a result, the one-time qualification rate of the products is improved and the company is able to win continuous trust from customers

Q:Tower crane installation, wind speed is greater than 12m/s, wind should stop operation,
Surface wind speed is greater than 6
Q:Is the tower crane a special type of work?
The crane driver, scaffolder, welders and other special types are
Q:What tower cranes are used on the 30 storey house?
According to the weight and the lifting range in order to determine the size of the tower crane tower crane lifting moment! Size to measure the lifting torque maximum weight * maximum weight of the amplitude of.QTZ63 represents 63 tons - meters, general building does not involve carrying heavy, almost 63!
Q:The role of slewing limiter in tower cranes is limited
The function of the rotary limiter is to limit the large arm to a certain set stop. Protect from turning to danger settingThe 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:What does "automatic tower crane" mean less than 100 tons per metre?
The crane must not exceed the maximum lifting capacity when working! Otherwise, there will be danger.
Q:Tower crane railing height is greater than or equal to meters
GB 6067 requires the height of the railings of the crane to be 1050mm, and a horizontal bar with a spacing of 350mm shall be provided. The bottom should be set at a height of not less than 70mm.
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 kind of bodies are tower cranes made of?
First, the working mechanism of tower cranesThe working mechanism of tower crane is usually composed of lifting mechanism, luffing mechanism, slewing mechanism, hydraulic jacking mechanism and running mechanism.The hoisting mechanism to realize heavy vertical up and down movement; luffing mechanism and slewing mechanism to achieve weight moving in two horizontal directions; hydraulic lifting mechanism of standard section, increase or decrease, so as to increase or decrease the tower; range of weights can achieve walking mechanism in tower crane and force of arbitrary space motion.
Q:What role does the tower crane torque limiter play?
The torque limiter can play the weight overload or working radius beyond, beyond the technical performance of the tower crane at the moment, immediately cut off their own lifting or variable power source, will send the alarm signal to prevent the occurrence of accidents.
Q:What are the climbing claws on the tower crane?
Climbing is lifting work cylinder claw pole on the standard main limb rod bearing points of the.
