The allowable contact pressure on concrete shall be 200 kg/cm², and the contact pressure on the jack’s ram shall not exceed 800 kg/m².
By default, the jack’s rated load capacity is set to 100,000 kg, and the contact area of the square spacer is set to 76 (=26×26) cm².
By default, the jack’s rated load capacity is set to 100,000 kg, and the contact area of the square spacer is set to 76 (=26×26) cm².
The thickness T of the spacer shall be sufficient to transmit the shear strength based on the ram diameter D. T ≒ D/6 to D/5
If deflection occurs in the load, T ≒ D/3.
If deflection occurs in the load, T ≒ D/3.

Ps = TJ/A
Determine the allowable value of the spacer contact surface pressure (kg/cm²) relative to the load (kg).
