PURPOSE: A steel pile draw bench is provided to prevent the downward twisting deformation of a pressurizing vice during a drawing operation of a steel pile. CONSTITUTION: A pressurizing vice(300) is supported with an elevation supporting plate(200). The pressurizing vice is touched with the upper side of the elevation supporting plate. The subscription vice pressurizes both sides of the steel pile. A pressurized oil-hydraulic circuit(400) moves the pressurizing vice in a straight line. An elevation oil-hydraulic circuit(500) up and down moves the elevation supporting plate from a base plate(100). |
