3 General requirements
3.1 The strength, rigidity and stability of the stacker and its parts and components shall
meet the requirements of GB/T 3811.
3.2 For main stress components, such as the following beams, columns, upper beams,
cargo platforms, hoisting mechanisms, the quality of the butt welds shall comply with
the requirements of Class II welds in GB/T 3323-2005.
3.3 Welding of structural parts shall comply with the provisions of GB 6067.1.
3.4 It shall take measure to prevent detachable connecting parts from self-loosening.
3.5 It shall take anti-rust measures for the metal structure and parts of the stacker.
3.6 The installation of the electrical equipment of the stacker shall comply with the
provisions of GB 50254.
4 Safety requirements for structural design
4.1 General requirements
The stacker shall be provided with devices to prevent overturning and derailment.
4.2 Requirements for cab design
4.2.1 The driver's cab shall have a good view for easy operation and maintenance.
4.2.2 The window material installed in the driver's cab shall be made of safe shock-
proof material. It shall have good transparency.
4.2.3 The floor of the driver's cab shall be made of non-slip and insulating materials.
4.2.4 The headroom of the driver's cab shall not be less than 1.9m. The width of the
door shall not be less than 0.5m.
4.2.5 The driver's cab door is not allowed to open outwards or downwards. Doors must
be fitted with locks or latches that interlock with the action of the stacker.
4.2.6 For the stacker with a lifting height of more than 5m, it must be equipped with
devices that the driver can safely leave the cab from a high position, such as ladders,
emergency exits.
4.2.7 The driver's cab shall not be made of flammable materials.
4.2.8 The lighting of the driver's cab must enable the driver to complete the normal
operation of the console. The illumination shall not be lower than 301x.
4.2.9 Emergency lighting shall be provided in the driver's cab.
4.2.10 The driver's cab must be equipped with an emergency stop button and a fire
6;
b) The safety factor of the wire rope strength with lifting cab shall not be less than
9.
4.7.3 The load-bearing wire rope shall be scrapped according to the provisions of GB/T
5972.
4.7.4 When selecting a load-bearing wire rope, the pulley shall be provided with a
device to prevent the wire rope from falling off the pulley groove.
4.7.5 When selecting a load-bearing chain, ensure that the chain drives smoothly on the
sprocket. Prevent jumping. Effective safety devices shall be set up and shall comply
with the provisions of GB/T 3811.
4.7.6 The fixing device at the end of the chain shall be safe and reliable. It shall be able
to withstand 2.5 times the chain tension without permanent deformation. The no-load
end of the chain shall be fixed firmly to ensure that it will not fall off.
4.8 Requirements for electrical equipment safety
4.8.1 The installation of the electrical equipment of the stacker must comply with the
