  • Page 27: Rules Governing Use

    5 RULES GOVERNING USE 5 RULES GOVERNING USE Before using the equipment, check the tightness of the piping and the correctness of assembly and also the connection by performing a dozen preliminary operations. The following instructions must be followed when using the equipment: 1.
  • Page 28 5 RULES GOVERNING USE All ATIB equipment is designed and manufactured according to a load positioned (with respect to its centre of gravity) at a certain distance from the vertical plane of the jaws. If the distance of the centre of gravity from the vertical part of the jaws needs to be increased, the weight of the load must be reduced.
  • Page 29 5 RULES GOVERNING USE The attainable sideshift may compromise the stability of the forklift truck. It is advisable to consult the manufacturer of the forklift truck to check the residual capacity of the forklift truck-equipment assembly. The condition of the road surface, the speed at which the load is handled and the elevation may all affect the load’s grip, which must be taken into account on a case-by-case basis.

  • Page 30: Integral Sideshift

    5 RULES GOVERNING USE 5.1 Integral Sideshift This is the type most frequently used in “GRIPPER WITH RUBBER JAWS TYPE 474.137 | GRIPPER FOR BLOCKS WITH SELF-BALANCING JAWS TYPE 474.141” and uses the same cylinders that clamp the jaws. The stroke depends on the opening and will be equal to zero in maximum opening and minimum closing.

  • Page 31: Handling Loads

    5 RULES GOVERNING USE 5.2 Handling Loads The minimum transportable dimensions must be greater than the minimum grip. Depending on the load to be transported, this difference may vary and must be evaluated on a case by case basis by the operator. Avoid handling and/or sideshift of the forklift truck/equipment with a load that is excessively high off the ground, as this may affect its stability.
