Features:

1. It has high working speed, good speed-adjusting performance, steady operation and high efficiency. Three-speed motor and mono-speed ratio decelerator are applied in the lifting struction, which enables heavy load low speed and light load high speed.
2. The range-change structure drives the dolly to change range on the horizontal arm, with good positioning performance. Planet gear decelerator is applied in the circumgyrating structure, together with moment-limiting hydraulic coupler, which can relize high load capacity, steady starting and reliable operation.
3. The crane has complete set of safety devices, which can guarantee the safe and high efficienct operation of the equipment. The machine is equipped with lifting height limiter, dolly range-change limiter, moment limiter, weight limiter, circumgyrating limiter, etc.
4. The operator's room is set independently on one side, with good vision field. It creates a good working environment for the operator.
5. Provide stepless speed regulation. Outstanding in working efficiency, operating stability and reliability,
6. This Tower Crane equipped with hydraulic lifting and connecting. This Tower Crane' s height can accordign to the actual height of the building and at the same time unchange the lifting capacity.
7. LVF: Frequency control, variable speed, smoothness and high stability, non-striking.
8. SM: Three-speed change pole motor, simple in structure, economical ,fitting.

Q:Were the anti-gravity machines used to build the pyramids levers, winches and cranes?
Levers winches and cranes all use a counter balance. Its weight that helps move weight in different ways. There is no such thing as an anti-gravity machine.
Q:How to learn the training of Crane style Kung Fu balance?
Balance is balance - there's no specific training but good balance will help you with all aspects of your training. A few things that helped me - tying shoelaces by getting into a crane posture rather than kneeling to the laces. The concentration on the shoe helps to balance you. Practice Crane Stance and try to keep a clear mind while in the stance - if you start worrying then you'll fall. Remember to keep the knee high and the foot pointed.

Q:Which are the crane manufacturing companies in India?
which okorder.com/ -indian Search engine-quite effective for local searches..
Q:Will Homeowners Insurance cover severe damage to driveway caused by crane?
No. The driveway is NOT a covered structure. The standard homeowners policy specifically excludes driveways from coverage. But the contractor who brought the crane in, should be responsible for it.
Q:lifting a machine by two crane?
Not enough information. What is the load weight? What is the size? How do you plan to attach to the machine. What size is the beam cross section? Capacity of the cranes? And so on. It sounds like you might need an engineer to supervise instead of relying on Yahoo Answers for an answer to a potentially deadly if not expensive way to fail.
Q:How were Railroad Steam Engines from 1830 to 1890's recovered before the advent of the Wrecker Steam Crane.?
Block and tackle. Some disassembling required. Consider this Stonewall Jackson raided Grafton WV and took several locomotives over land to a southern rail head. The special equipment was developed due to increased engine size. When steam cranes were/are used temporary tracks are laid at the wreck site for several reasons. one of which is to get equipment in and the other is to haul the wreckage out. The actual number of cranes required depended on the engine/s in the wreck, location on the wreck, skill of the operators and extent of damage. If the locomotive was damaged to much, it might be cut up. If the location was too difficult for recover, they were abandoned or buried. Rumor has it that there are several locomotives left at the bottom of slides awaiting for some one with enough money to recover them for restoration. Like the story of legend concerning a 1953 Corvette in a old barn. Hope that answers all your questions.
Q:Who should defend God, Denny Crane or Alan Shore?
god is not guilty of any crime men are guilty of the crimes they commit its not a crime to know things are going to happen
Q:Under what circumstances are winches used and under what circumstances tower cranes are used?
First of all, what you say should be a derrick or a Longmen frame. In any case, the derrick or tower crane should first meet the construction requirements, then the economy and safety requirements. To meet the construction requirements, it is much better to choose the derrick, of course, economically and safely. Derrick is a simple nonstandard equipment. It is easy to install, use and disassemble. It has low running cost and less safety risk than tower crane. The derrick is suitable for construction under 30 meters or less, especially for multi storied buildings and single pieces. The volume and quality are not more than 2 tons.
