Q:Lifting mechanism in tower crane: M5. Luffing mechanism: what does "M4" mean? Seek expert answers
It is the work level of the organization, representing the working hours and load sizes of the institution. See GBT/13752 or GBT/3811 for specific explanations.
Q:What are the safety devices for tower cranes?
(6) the rail clamp is used to clamp the rail, prevent the crane from walking by wind in the strong wind, and cause the tower crane to derail and overturn the accident.(7) the wind meter automatically records the wind speed, and automatically alarms when more than six wind speed is over.(8) the anti stripping device of the steel wire rope is mainly used to prevent the steel wire rope from disengaging from the pulley groove during the transmission process(9) the hook insurance prevents the lifting of the steel wire rope because of the excessive angle or the wrong hook, and causes the lifting wire rope to be broken off and the suspension falling accident.
Q:Method for operating tower crane
In the 2.11 operation, when lifting the weight, the weight should be higher than the height of the obstacle, at least 100mm.2.12 when the crane is approaching the track limit, it should slow down and stop in advance.2.13 when lifting heavy objects, not heavy lifting suspension instability, no additional weight in lifting objects, lifting scattered materials or special-shaped components must be used when the wire rope firmly tied to heavy lifting from the ground about 50cm stop, determine the brake materials, lashing and rigging, confirmation before lifting command.2.14 cranes must be adequately illuminated at night.2.15 crane in the stop, rest or midway power failure, the weight should be unloaded, not to weight suspended in the air.2.16 the operating room, no personnel shall enter, prohibited flammable and impede the operation of the items.2.17 is strictly prohibited or promotion personnel riding crane. Landing weight, weight is prohibited to stand.2.18 the boom and lifting pieces of cranes must be in safe distance from overhead transmission lines, and shall comply with the provisions of this schedule 30.1.6.2.19, two cranes in a track or two parallel or vertical orbit on the operation, should maintain the safety of any part of the distance between two machines, the minimum shall not be less than 5m.2.20 in case of any of the following circumstances, suspension operation shall be suspended:1., in the event of bad weather, such as heavy rain, heavy snow, fog and construction work surface has six (including six) above the strong winds, affecting safety construction.2. crane leakage occurs.3. serious wear of wire rope, to scrap standard (wire rope scrap standard see Appendix A).4. safety guards fail or display inaccurate.
Q:Tower crane body standard section connection bolt screw upward or downward, why?.
Usually it is worn from top to bottom, so that the nut is loose and the bolt will not fall directly
Q:Tower crane 5610 why is it called QTZ63?
Strictly speaking, 5610 should be called TC5610;At present in the domestic type mark in two ways: one is QTZ++, one is TC++, for example, such as QTZ80, Q is the first letter of Chinese "play", T is the first letter of Chinese "tower", Z is the Chinese "from" the first letter is self lifting tower crane 80, the unit is 80 tons of tons of rice, rice is a concept called lifting torque, rated torque, maximum rated product weight and maximum range; as in the 13.4 meters lift 6 tons, the product is 80 tons of rice;Such as: TC6010, T is the English TOWER, C English CRANE, TC tower crane is English shorthand, the 60 refers to the jib 60 meters long, 10 refers to the boom in the front 60 meters lift 1 tons, and TC5513 refers to the boom length of 55 meters, the front suspension of 1.3 tons. TC tagging is an international universal annotation. Domestic commonly used models areQTZ series: 40, 63, 80, 100, 125, 160,200, 250, 315
Q:Equipment safety of tower crane
Some use units over profit, not pay attention to safety, small horse cart, overloading seriously, tower crane accident is one of the main source of high incidence. Some manufacturers in order to meet the construction requirements of the enterprise, expand sales, to occupy the market, will be independent of height increase, the boom will be lengthened to increase the tower coverage, this is bound to reduce the stability of tower crane, reduce the rated lifting weight, increased insecurity. There are some private and unauthorized modification of the tower crane tower crane in the assembly, this part of the tower crane for a long time in the second-hand purchase price is cheap, not willing to invest in maintenance, and frequent failure, which should arouse our attention, we should seek truth from facts, according to local conditions, to solicit the views of all parties on the basis of the introduction of relevant the supporting policies to solve this problem. By strengthening the safety management of several aspects of tower crane, it can effectively prevent all kinds of accidents in the process of tower crane use, and play a preventive role. Practice shows that as long as the construction enterprises, factories, construction administrative departments, in accordance with the tower crane detection institutions can each link to do, to strengthen the safety management of the tower crane, can effectively control the incidence of major accident of crane.
Q:What are the lifting moment requirements for tower cranes?
3, tower crane, such as lifting weight limiter, amplitude limiter, height limiter and load torque limiter limiting device, and travel limit switchestower lights wind instrument, wind clip rail device ladders athletic supporter circlewalkways and railings. The driver's cab is comfortable, easy to operate, with good vision and perfect communication facilities.
Q:What is an attached tower crane?
Attached tower craneAttached tower crane is arranged close to the building, the tower by themselves to rise up with the increase of buildings and roof, tower, every 20m with attachment support device, the tower body is fixed on the building, in order to maintain stability. Figure 11 is a QT4 - 10 self - elevating four - tower crane (attachable, stationary, walkable, and climbing).
Q:What is the difference between a crane and a crane in a tower crane?
There are the following differences between crane crane and Signal Engineer in tower crane:1, lifting signals refers to those who signal flags in the works.2, the engineer referred to the engineer who tied the rope in the works.
Q:What are the safety devices for the horizontal arm self lifting tower cranes?
(1) the lift height limit position limiter must be able to stop lifting motion immediately when the lifting device is raised to the 8OOmm at the lower end of the boom. For luffing cranes, lift the top of the hook to the lower end of the frame 500mm. The lifting movement must be stopped immediately. (2) lifting moment limiter and maximum weight limiter; when lifting torque reaches 90% of its rated value, the lifting torque limiter shall be able to issue an acoustic or red light to indicate the alarm. When the lifting torque exceeds its rated value and reaches 108% of the rated value, the lifting direction and outward direction shall be stopped. If the weight and amplitude indicator are set, the numerical value should be correct, clear and eye-catching. The digital error shall not exceed 5% of the indicated value. When the lifting weight exceeds the maximum weight, maximum lifting weight limiter should emit light or sound alarm, when the load exceeds the maximum weight of 6%, should stop to enhance the direction of movement, but to allow institutions towards the down direction.
