5 Installation Requirements for Lighting Transformers of 36 Volt and Below
5.1 The power supply side should have short-circuit protection, and the rated current of its fuse should not exceed the rated current of the transformer.
5.2 The shell, core and any low voltage side or neutral point should be grounded or connected to zero.
6 Fixture Requirements Fixed on Moving Structures
Its wire should be laid inside the moving frame. The wires should not be subjected to tensile forces and wear during movement of the mobile frame. When the chandelier luminaire weight is more than 3 kg, it should be fixed by a pre-embedded hook or bolt; when the weight of the chandelier luminaire is more than 1 kg, a hanging chain should be added.
7 Metal Halide Lamp Installation Requirements
7.1 The installation height of the luminaire should be more than 5 meters. The conductor should be connected to the luminaire through the terminal and must not be near the surface of the luminaire.
7.2 Lamps must be used with triggers and restrictors.
7.3 Reflective lighting fixtures installed on the floor shall take protective measures.
8 Installation requirements for decorative lamps embedded in ceilings
8.1 The luminaire shall be fixed on a dedicated frame. The conductor shall not be close to the lamp housing and there shall be a margin in the lamp case. The frame of the luminaire shall be tightly attached to the ceiling surface.
8.2 The frame of the rectangular lamp should be parallel to the decorative surface of the ceiling. The deviation should not exceed 5 mm.
8.3 Open-type luminaires with combination of fluorescent tubes shall be arranged neatly and their metal or plastic spacers shall have no defects such as distortion.
9 Lantern installation requirements
The hook of a fixed lantern shall have a diameter of not less than the diameter of the hanging hook of the lamp, and shall not be less than 6 mm. For large lanterns, the fixtures and suspensions for ceiling lanterns shall be tested as 1.25 times the weight of the fixtures. The glass cover of a large-sized lighting fixture installed in an important place shall be designed to prevent the spatter from falling down after breaking.
10 neon installation requirements
10.1 The lamp should be intact and free of cracks.
10.2 The lamp should be fixed with a special insulating bracket and it must be firm and reliable. Special brackets can be made of glass tubes. The minimum distance between the fixed lamp and the surface of buildings and structures should not be less than 20 mm.
10.3 The length of the lamp for a neon dedicated transformer shall not exceed the allowable load length.

Transverse Conveyor
The Transverse Conveyor Unit stands as a pivotal component within the Pallet Conveyor System, playing a key role in facilitating the smooth transition of pallets between vertical and horizontal conveyor lines. This essential unit ensures the seamless flow of pallets, enabling them to navigate both longitudinal and transverse conveyor lines with precision and efficiency. By facilitating this versatile movement, the Transverse Conveyor Unit contributes significantly to optimizing the overall functionality and adaptability of the Pallet Conveyor system in diverse industrial settings.
