General knowledge of crane

What is the best use of frequency? This can ask your crane contract firms to check the usage of cranes in a quarter, half a year or a year. This is a good opportunity for you to communicate with your crane contractor, and they will make some relevant suggestions based on the extent of your crane use, such as when you should check the limit switch and the method of inspection.
 Anchorage points for cranes with handcart and beam splint.
 One kind of flange is fixed with a cart and a beam clip that we can see on a moving lift, a cantilever crane, or a bridge type crane. The main  purpose of fixing these two machines is to provide an anchor, which must be stable and reliable in order to install other hoisting devices with similar cranes.
 What are the most important changes between clamps and trolleys?
 First, the beam tongs are the clips locked on the steel beam. It is a semi permanent lifting accessory capable of hanging a lifting device on top, with chain sliders, hoists, or lifting magnets hanging. It is called semi permanent device because it is fixed in one location and can not be moved. If the load above is separated, it will disconnect and locate a new position along the beam. The size and lifting capacity of the beam jig are different and can be used on most of the cranes, and the hooks can easily be attached to the equipment so that they can be easily suspended and promoted. Its installation is relatively simple, and the spreader beam is used in pairs, but if the total method is used to hoist goods, the No. 1 clamp can not exceed the safety load. The hoist equipped with beam CL is up to 10 kilograms.
 In order to make the lifting machine easier to install, the beam type car is usually designed as "H" shape, so that the shape of the  gear mechanism can be used by the gear mechanism model by pulling the chain manipulating machine and the steel wheel on the tram. The ball bearings above can ensure that the car runs smoothly, and the above gear and power models allow the small cars to be placed more accurately, allowing them to maintain the smooth transport in the case of load, and then by using the simplest drive version of remote control. This is a major advantage of beam clamp, and if necessary, it can be installed by locking the device.
 When lifting heavy objects, the appropriate beam clamp and the size of the car are the safest. We must ensure that it can be firmly attached to the beam so as to ensure the safety of operators and workers. Moreover, when using a crane, it must not exceed the safety load, and the beam can bear the weight of the load alone.
 The "H" shape steel girder is equipped on all types of cranes, so crane can use beam clamp and trolley system. Both of them are simple to install. They can adapt and maintain the crane under the condition of providing safe anchor points. It is similar to electric hoist, chain block, lifting magnet, ratchet lever and other mechanical replenish hoisting device.
 Installation of deck cranes on yachts.
 Within a certain period of time, cranes can be used anywhere. For example, on construction sites, cranes can lift and reduce heavy materials and transfer them to wherever they want to move. But if a crane is in a  factory, its function changes, and it can load heavy products into trucks or warehouses. It also has other functions, such as lifting and moving heavy tyres from large trucks, which is more suitable for truck transportation and mining sites. Cranes have been widely used in cities for all kinds of electrification maintenance and other work.
