The invention aims at providing a loading platform high in control accuracy and capable of performing real time monitoring and automatic adjustment, and a level adjustment control method of loads. The level adjustment control method of the loads includes: collecting data of a level instrument; unitizing dip angles under a coordinate system of the level instrument; using a transformation matrix to transform an expression (i'0, j'0, k'0) under the coordinate system of the level instrument into an expression under a leveling target, setting the loading platform as a leveling target, changing the expression(i'0, j'0, k'0) of the dip angles into the other expression (i0, j0, k0), and obtaining value of the current dip angle; subtracting the current dip angle from an initial installation dip angle so as to obtain an adjustment angle; leveling support legs of the loading platform once again, and adjusting displacement. According to the loading platform and the level adjustment control method of the loads, the dip angles of the level instrument can be monitored in real time, the level instrument can be automatically adjusted in real time when deviation occurs, manual operation is not needed, efficiency is high, control accuracy is high, reliability is high, and when one support leg is jammed, the leveling target is leveled by adjusting the other three support legs.
