1, the total weight of large equipment is heavy, so if the application of a single crane to do the lifting, most will use the rated total weight of more than 50 tons of crawler crane. This is because the chassis is relatively stable, the total lifting weight is large, so in large lifting, lifting companies are particularly common.

2, the double machine. The two-machine lifting bar is also known as the two-car lifting bar, which is usually the application of two crawler cranes, which are different in the lifting point. The double machine hoist is mostly used for the total weight of the equipment, which exceeds the load of the single machine. Or the shape of the equipment is relatively strange, and the application of two cranes is conducive to lifting.

3. Bridge crane hoisting. The bridge crane belongs to one of the fixed cranes. It is characterized by large lifting weight and smooth operation. However, its early installation is relatively complex, so it is used for port container hoisting. Unconventional lifting. Non-conventional equipment to do large lifting mainly includes helicopter lifting, mast lifting, tower crane lifting and so on.

4, equipment lifting and handling method: rolling up and rolling down method. Important refers to one of the degree of loading and unloading methods of port loading and unloading, manipulating forklift trucks or semi-trailers, cars to carry goods, equipment handling and vehicles to drive on board together, and then drive off the ship after reaching the destination, called "roll up and roll down" method. The rolling on and rolling off method of the forklift truck, after unloading on the ship, the forklift must leave the ship, the semi-trailer, flat car or car is operated, and the semi-trailer and flat car are tired to the ship, and the truck is driven off the ship and the cargo vehicle is transported to the destination together with the goods, and then the original car is driven off or the trailer is loaded onto the ship and the semi-trailer and flat car are driven off.
