11 meter overturned dump semi-trailer
Hydraulic top is an important component for rollover, generally ranging from 110 to depending on the load capacity A125、A130A、 For diameters of 150 and other sizes, generally with a standard load of no more than 60 tons, use 110's 5 1 (5 lifting cylinders, 1 shifting cylinder) or 130's 4 1; For heavy loads ranging from 80 to 120 tons, typically a 150 ton hydraulic cylinder with 6 or 7 1 is used. The displacement top usually uses a 160 or 180 cylinder. The brand that is commonly used is Haiwo, which has good quality and service, but the price is relatively expensive. There are also other general brands, including the 5 1 with liquid pump power take-off 110, which costs nearly 10000 yuan per set. The hydraulic top bracket carries a large part of the weight of the goods during lifting, and the firmness of the bracket is very important. The shaft at the connection between the hydraulic jack and the subframe should be well protected, otherwise it is easy to bend. The more important supporting points for slant support reinforcement, the higher the reliability.
