A support for height control of heavy load is provided to prevent deformation or damage of the support bolt even when the length of the support is adjusted. A support for height control of heavy load comprises a support bolt(10), a control unit(50), a finishing cap(30), and a frictional member. The support bolt is installed in the heavy load and is allowed to be exposed. The control unit is coupled with the head of the support bolt. The control unit comprises a handle(51). The control unit rotates the support bolt. The finishing cap is supported by the head of the support bolt and is permitted to rotate. The frictional member is interposed between the head of the support bolt and finishing cap.
