What is the benefit of the four metal brackets in the rear of the car when lifting the crane
You can simulate this, a person feet and feet standing on the ground and feet open knees, if this time I give him a bucket of water, let him mention, naturally you can imagine that action is more natural and stable.
Hydraulic truck crane in the lifting of the four brackets open, obviously increased the weight of the station when the area, a solid crane center of gravity, but also play a supporting role, so that when the lifting time will be more stable.
Of course, the crane is not so simple, in the design and manufacture of the time, which contains a lot of physical mechanics in the inside
