  • Page 23 5 USE RULES In this occasion, we suggest to control the chart Picture 18, where, according to the increase of the centre of gravity (x-axis) there is a load reduction multiplying factor (y-axis). The multiplying factor, obtained based on desired load centre position, will be multiplied with nominal capacity of the equipment.
  • Page 24 5 USE RULES The condition of the soil, the quickness of the movement of the load and the lifting height can affect the hold of the load and must be taken into consideration as regards specific occasions. Side shifting movement is forbidden in movement. Side shifting movement in condition of lifted mast is permitted only to bring back the load at the center of the mast.
