Description of our Tower Crane
The tower crane is a combination of advanced technologies of the present day. The electric control system of the tower crane adopts the advanced “PLC + frequency converter” control mode of the present day, which has realized the stepless speed regulation and greatly improves the reliability, maneuverability and stability of the control system and the work efficiency of the tower crane.
The tower crane is equipped with all kinds of reliable safety devices, such as hoisting height limiter, slewing range limiter and multifunctional limiter to control the load moment, hoisting capacity and trolley traveling range. Its PLC (Programmable Logic Controller) unit can diagnose the cause of breakdowns. Its Safety Monitoring System (also known as Black Box) displays the data of working radiuses, heights, moments and weights.
The use of world-famous electric components such as OMRON, YASKAWA, Schneider (TE) and MEAN WELL greatly reduces the failure rate of the electric control system and improves the work efficiency of the users.
Besides, there are also electric safety devices like anemoscopes and obstacle lights and mechanical safety devices to prevent the breaking of trolley axles and wireropes.
Advantage of our tower crane
1, boom relief Angle is big, greatly widened the equipment capacity and scope of work.
2, suitable for the group of tower cross homework.
3, boom stability is good, combination amplitude range.
4, suitable for height have special requirements occasions construction.
5, lifting capacity big, effectively solve the high steel structure construction team crane big lifting capacity requirements.

- Q: I work a few blocks away and my window faces the building, now shrouded in black netting and scaffolding. I cannot comprehend how that crane got up there!!
- They do it a few diferent ways: (1) They use another crane to put it up there (2) They fly it in - either whole or in pieces - usually with a set of helicopters (3) The pieces are lugged up in an elevator and assembled up on top Seriously, most cranes are bought to the site in pieces and assembled on the fly. They can usually put them up in a span of a few hours. They have the erection of the cranes down to a simple science nowadays. They can also build the crane by using a small crane at the start and building on that until they expand it out to a large one.
- Q: What special operators should be equipped for the installation and disassembly of tower cranes?
- 2, with construction qualification certificates for special operations of the construction hoisting machinery installation and disassembly, lifting work, special operation signal heavy drivers, riggers and other operations personnel. And an electrician.
- Q: I need to draw an injured crane (the bird) with an arrow in its wing, lying on the ground...preferably with a splayed wing.How do I draw this? Sketches would help.Thanks.
- Shoot a crane with an arrow and take a picture. Life drawing and technology mesh well.
- Q: I am sick and tired of sitting in my room scared looking at a crane fly bouncing around mu walls like its on crack , is there anything i can do to keep the c*nts out
- get ur boyfriend or girlfriend to kill threm for you or your besty katy!
- Q: The cantilever part has to stay at least 6-12 inches off the ground.
- Popsicle Stick Crane
- Q: The truck has a Comprehensive Motor insurance cover. There is no exclusion in the policy in respect of tools of trade.
- read your insurance policy.
- Q: Flocks of cranes shout'. Is it right to use the word'shout' here?
- If that's what it sounds like, sure.
- 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.
- 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.
- Q: A 3000-lb wrecking ball hangs from a 40-ft cable of density 10 lb/ft attached to a crane. Calculate the work done if the crane lifts the ball from ground level to 40 ft in the air by drawing in the cable.
- The total work done by the crane equals the potential energy gained by the wrecking ball and the cable; the potential energy gained is W = V_final = Mg L + ρ L g L/2 which is the final potential energy of the wrecking ball and the cable added together. In the case of the cable, you take the center of mass of it which is located right at the center (L/2). The result is then W = 3000*32*40 + 10 * 40 * 32 * 40 / 2 = 4096000 ft-lbf = (4096000)*(0.001285067) BTU = 5263.63 BTU
