750*1000 Cast iron platform and the above platform are generally designed with four symmetrical lifting hole, It is convenient to load.  In order to prevent deformation of the cast iron plate from lifting,it usually use the same length of rope while catching four cast iron have four lifting holes on the plate, cast iron plates on smooth hoisting conveyance.

   It is very dangerous that Some users only diagonal lifting methods so readily inclined to make flat hook from lifting out of the hole.
70*1000 Cast iron platform generally have 3 support points, and the greater one usually have 4 support points.When the length great than 2,000 ，it will have a basic strong point per meter.

    When using cast iron platform, cast iron platform will first support point cushion good pad level, to ensure that each anchor force uniform, to ensure a smooth whole cast iron platform. Then by professional and technical personnel qualified to adjust the cast iron plate accuracy.

To take in the light cast iron platform test work piece-light parts, rough work pieces do not move on a cast iron plate, cast iron platform to avoid bump on the face, scratches and other damage. In order to prevent deformation of the whole cast iron plate, after use, to win the work piece from a flat iron to avoid artifacts caused by prolonged heavy pressure on the cast iron plate iron plate deformation. Fear of wet cast iron plate, cast iron plate should be installed in ventilated, dry environment and away from heat, corrosive gas.
