Installation steps for a European Type Bridge Crane

1.Site Survey and Safety Precautions:

• Conduct a safety survey of the installation site, addressing any safety hazards.
• Provide on-site safety education for all operators, emphasizing safety requirements and precautions.
• Install safety ropes (12mm wire) along both sides of the track beams.
• Prepare necessary climbing equipment and set up safety warning signs.

2.Track Installation:

• Lift the crane track onto the load beam using appropriate equipment.
• Prepare track accessories and tools for installation.
• Measure the span and level of the crane.
• Pull the rails onto the steel frame using a hand hoist and secure them with bent hook ross.
• Weld the end car gears to the track ends to ensure uniform contact with the crane buffer.

3.Main Beam Installation:

• Lift the main beam of the crane onto the track using a crane.
• Choose appropriate length wire ropes and ensure proper coordination and safety during lifting.

4.Electrical Installation and Commissioning:

• Connect the electrical control system according to the crane’s product drawing.
• Connect the safety contact line collector/reel flexible cable.
• Install limit switches as per the drawings.
• Mount a three-phase power indicator at the end of the track.
• Install the power supply air switch and connect it to the safety sliding contact wire/reel flexible cable.
• Measure the insulation resistance of the main circuit and control circuit to meet relevant standards (GB50256-96).
• Ensure electrical installation complies with GB50256-96 and GB6067-85 standards.

5.Testing and Commissioning:

• After installation, conduct debugging of the crane to ensure all components function correctly.
• Test the hoisting operation to verify the effectiveness of each safety protection device.
• Complete track debugging for the European-style bridge crane.
• Confirm there are no errors before delivering the crane to the user.

These steps outline the systematic process for installing a European Type Bridge Crane, ensuring safety, proper installation of components, and adherence to electrical standards before commissioning.
