What should not be the grid spacing between the poles of the safety head living frame of the stacker?

The recommendation for grid spacing between the poles of the safety head living frame on a stacker is crucial for ensuring both safety and operational efficiency. The correct answer indicates that a spacing of 16cm is not acceptable, likely because it does not provide adequate support or protection.

In stacking equipment, the poles must be closely spaced to minimize the risk of accidental contact or entrapment hazards when the stacker is in operation. Excessive spacing could lead to instability of the safety framework, which is designed to protect the operator from potential overhead loads. Safety standards generally recommend tighter spacing to enhance structural integrity and safeguard against falls or equipment failures.

Other specified distances like 10cm, 14cm, and 20cm are more aligned with safety guidelines, offering the right balance between support and maneuverability while ensuring that safety measures are not compromised. Therefore, the choice of 16cm is recognized as inadequate for maintaining proper safety standards for stacker operations.
