Q:What is a tower crane without a collector?
Without the collector, the main cable of the tower crane directly reaches the power distribution cabinet after turning.
Q:What special operators should be equipped for the installation and disassembly of tower cranes?
According to the requirements of the 2.0.3 specification: tower crane tower crane installation and disassembly operation should be equipped with the following: 1, hold a qualified safety assessment certificate of the project and responsible for the safety of people and machinery management personnel;
Q:What is the insulation resistance of tower crane?
Three. Technical specification for temporary power safety on construction site JGJ 46-20055.4.2 within the construction site crane, derrick and Longmen machinery equipment, metal structure and steel scaffolding and under construction in construction projects, when lightning protection devices in adjacent buildings, structures and other facilities outside the protect zone of lightning arrester, lightning protection device should be installed in accordance with the provisions of.5.4.7 lightning protection electrical equipment machinery, connected to the PE line must repeat grounding at the same time, with a repeat of the mechanical and electrical equipment grounding and lightning protection grounding machines can share the same grounding body, but should be consistent with the repeated grounding resistance of grounding resistance requirements.The electrical equipment of 9.2.1 tower crane shall comply with the requirements of the current national standard "safety regulations for tower cranes" GB5144.9.2.2 tower cranes shall be subjected to repeated earthing and lightning protection grounding as specified in Clause 5.4.7 of this code. The earthing device of the track type tower crane shall comply with the following requirements:L the two ends of the rail are respectively provided with a grounding device;The joint of the 2 track is electrically connected, and the ends of the two tracks are electrically connected in the loop;3 long track every is not more than 30m and a grounding device.
Q:What parameters are lifting machines called large equipment? 200
Said here [] large equipment is a concept that means assessment of whether you did more complete, more complex, (conceptual) large equipment, imagine that you provide [small] equipment detection report may not require? If you can provide a full set of drawings of a mobile phone, it will be recognized, but the mobile phone is never a large [device], the key point, appraisal is the assessment of your ability, to see if you have experienced, or complete certain system equipment manufacturing processThere should be no concept of magnitude, and it's really not a good division of magnitudeAs many job posting said, that is the requirement of [bachelor], college students will be delayed if from yourself, if you have the strength, should be bold to recommend myself, because any recruitment notice can't say: we only recruit college students......
Q:What are the necessary safety devices on a tower crane?
(1) lift height limit position limiterFor cranes with variable boom angles, the lifting motion must be stopped immediately when the top of the lifting device rises 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 lift limiter;When the 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.
Q:What is the difference between crawler crane and tower crane?
Difference:1, tower crane tower body (lower) stand up like a tower, so called tower crane; crawler crane slewing below is tracked chassis, like crawler tractor chassis.2, tower cranes are generally used in high-rise building construction, lifting and attaching, arm pole is very long, construction site is very common. Crawler crane is used in municipal engineering, such as subway, bridge and so on.3, the tower crane jib with flat arm, arm, is mainly composed of steel frame. Crawler crane boom is mostly steel frame, similar to the tower crane boom.
Q:Safety rules for tower cranes
Three. Check after shutdown3.1 after the tower crane has stopped operation, it is necessary to select the suitable position of the barrier and the middle of the track when the turret is turned and the arm to stop along the wind, and then lock all the rail clamps.All 3.2 tower crane rotary mechanism with a normally closed or braking device, in the stop after the operation, the driver must remove the handle, release the brake for crane in the wind blowing in under the direction of rotation.3.3, the hook should be lifted to the minimum distance from the lifting wall, not more than 5m position, hanging on the hook is strictly prohibited. Not to take reliable measures, not by any means, limiting the boom rotate with the wind.
Q:Can the attached arm of the tower crane be welded?
The following points: the calculation of tower crane according to the instructions provided with the attachment of the building, a maximum load attachment device (Fig. 14-44), therefore, should be in the way of adhering bar load as the design or check attached bar section basis.
Q:What are the safety devices in a tower crane?
1 torque limiter. There are two kinds of mechanical electronic.2 weight limiter. There are two kinds of mechanical and electronic.3, lifting limit device.4, slewing limit device.5, amplitude limiter.6, car anti break shaft device.7, the car anti broken rope device.8, jacking up anti stripping device.9, the collision lights.10, luffing tower crane luffing speed protection.11, walking crane limit limiter.12, all kinds of warning signs.
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.
