The spacing along the height of the retaining wall piece must comply with the installation instructions for the tower crane;
Q:What are the main technical parameters of a tower crane?
Generally speaking, the main parameters of the tower crane are:Maximum amplitude unit MMaximum lifting height, unit MMaximum lifting torque unit KN.mMaximum lifting speed unit m/minMaximum lifting unit tRotational speed unit r/minVariable speed unit m/min or o/minWalking speed per unit m/minMotor power unit w......Please refer to the product manual.
Q:What tower cranes are used on the 30 storey house?
but if the building steel structure more parts or building the number of square meters more than 60 thousand square meters, you need to consider QTZ80 or more of the tower crane, because the type of large lifting capacity is big, the work efficiency is high. Hope to be of help to you!
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:How to select tower crane type according to the height of building? Seek explanation
The building cornice height within 20m, the building area of each floor within 2000m2 with 800KN.m tower crane 1 units, each increase of less than 1600m2 800KN.m 1 tower cranes;The building cornice height is less than 50m, the building area of each floor within 2500m2 with 1000KN.m self lifting tower crane 1 units, each increase of less than 2000m2 increased 1 1000KN.m self lifting tower crane;The building cornice height is less than 100m, the building area of each floor within 3000m2 with 1500KN.m self lifting tower crane 1 units, each increase of less than 2500m2 increased 1 1500KN.m self lifting tower crane;The building cornice height is above 100m, the building area of each floor within 3500m2 with 1 2000KN.m self lifting tower crane, each increase of less than 3000m2 increased 1 2000KN.m Jack 1 cranes;When the eaves height more than 25m below the 100m, according to each self lifting tower crane with 1 single cage construction elevator, eaves height above 100m with 2 single cage construction elevator;The podium when every floor area is too large, in accordance with the above standard auxiliary tower crane.
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:Tower cranes should stop working when the wind speed is greater than the magnitude.
Rules for safety regulation of tower crane,The installation of tower crane is strictly prohibited at grade 4 or above
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 is the difference between lifting height of tower crane and independent height?
Attachment can be understood as the kind of tower crane tied to a building. Without it, the tower will fall, and its strength, stiffness and stability can not be satisfied.
