QTZ31.5 FAQ
Q: What is the weight for one piece of counter weight?
A: One piece counter weight is 25kg.
Q: Can you equip with light on tower crane jib, monitor, remote control and anemometer?
A: Sure. All of these could be provided with extra cost upon the clients’ requirements. But according to general practice, remote control is not suggested because most of the operator feedback operation in the cabin will provide a wide working view.
Q: What is 3 main mechanism of the tower crane?
A: there are trolleying mechanism/ slewing mechanism/ hoisting mechanism.
- Q:Equipment safety of tower crane
- Safe distance tower and transmission line is not up to the requirements of the tower frame door frame to design, erection principle to power erection, do not use metal materials, bamboo and other materials can be used. The distance between a bamboo pole and a power line shall not be less than 1m, and a certain degree of stability shall be taken to prevent the wind from blowing. The tower crane height and bottom bearing size ratio is large, and the center of gravity of the tower body, high torque, braking frequency, impact force, in order to increase its stability, we will analysis the main causes of the tilting of the tower crane has the following:Overloading. Different types of cranes usually adopts the lifting torque based control, when the amplitude exceeds the rated load weight increase or the corresponding weights, the overturning moment more than stable moment of it, it may cause the collapse of the tower crane.Two, inclined hanging. Slant weights will increase its overturning moment, the lifting point will produce horizontal force and vertical force on the crane, bottom supporting point will produce an additional overturning moment, and the stability coefficient is reduced, resulting in tower crane collapse.Three, the tower crane foundation is uneven, the ground endurance is insufficient, the perpendicularity error is too big, also can cause the tower crane to overturn the moment to increase, causes the tower crane stability to reduce. Therefore, we should proceed from these key factors to strictly check, check and check, and prevent major equipment personal safety accidents. State explicitly eliminated the model should resolutely prohibit the use of, in disrepair, tower crane in the identification of the repair, to limit the use of load, tower crane for the use of fixed number of years there is no uniform standards, opinions vary, different places have different provisions.
- Q:Do they come all the way down?
- the operator turns the engine off and puts the crane put it into safety mode so it doesnt hurt near by workers and open the door of the crane but before he does anything els he first turns on the alarm on so no one steals the 5 ton crane when the operators in the bathroom taking a crap/piss doing whatever...
- Q:I'm into urban exploration and basically the one thing I haven't done is climb a crane. I don't actually know where one is that I could climb, but I definitely will do it someday. I'm just wondering how illegal it would be? Also, don't give me any it's not safe bull, I'm perfectly confident in my abilities and ready to accept the consequences if I get caught.
- Here comes Chuck again with his everlasting wisdom. Heres Chuck:Climbing a crane is illegal. I love guns, and law and order!! My politics lean to the right. blah blah blah. Climbing a crane would be AWESOME. You should do it. videotape it, and post it on youtube for all to see.
- Q:does it only carry thousand of pounds stuff or wat?? for science project??
- A crane is a mechanical lifting device equipped with a winder, wire ropes and sheaves that can be used both to lift and lower materials and to move them horizontally. It uses one or more simple machines to create mechanical advantage and thus move loads beyond the normal capability of a human. Cranes are commonly employed in the transport industry for the loading and unloading of freight; in the construction industry for the movement of materials; and in the manufacturing industry for the assembling of heavy equipment
- Q:need a 5 ton jib crane design with drawing please help, boom 12ft hub 16ft?
- Hello, okorder /
- Q:if the crane starts out at ground level and the skyscraper is being built next to it, how does the crane get moved to the top of the building once the skyscraper has been built to the level of the top of the crane? (eg: the crane can reach a height of 30 stories but the building being const. is 100 stories)
- it takes two cranes
- Q:What are the safety devices in a tower crane?
- Answer: 1: height limit2: lifting weight limiter3: torque limiter4: travel limiter5: speed (maximum speed of force must be more than 40m/min)6: put a device (jib tower crane to move) must have7: the rotary limiter (no collector on the revolving part) must have8: car broken rope protection9: anemometer (boom root hinge point height is greater than 50m should be set)10: windproof device (rail type)11: buffer and end stop12: Rail sweeping plate (rail)13: protective cover14: derailment device15: emergency power off switch (red mushroom head)
- 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:how do you win at the crane game?
- im the master of the crane game. You gotta scope out the animal first! If it looks heavy then dont even bother. Whenever you grab hold of something its gonna pull it up and shake when it hits the top right? Thats why you go for something close to the hole it drops in. They have one where I work so I lock the wheels, grab the animal and pull the whole machine forward so that it just falls in the hole lol.
- Q:I am doing uni coursework to design an ergonomic layout for an operator cab for a tower crane and so I need to list the required operator controls.Thanks!
- There are only two control levers that are on a tower crane.There is one on either side of the seat called joy sticks the right side joy stick controls the hoist cable to go up and down pushed forward to go down and pulled back to hoist up.The left has four functions it controls the swing of the crane and also the boom of the crane to control the swing you push the lever to the left to swing left and push the lever right to swing right.You pull the lever back to boom up and puh it forward to boom down.
