Hur bygger man en portalkran?

Building a gantry crane is a complex engineering project that requires comprehensive consideration of multiple aspects such as design, material selection, manufacturing, and installation. The following are the main steps for building a gantry crane:

1. Requirements analysis and design

Requirement analysis:

Clarify the specific requirements for the purpose, working environment, lifting capacity, span, lifting height, etc. of the crane.

Preliminary design:

Conduct preliminary design based on requirements, determine the basic parameters and overall layout of the crane.

Detailed design:

Conduct detailed design, including structural design, mechanical design, and electrical design. Draw detailed design drawings and technical specifications.

Choose suitable materials, such as steel, motors, transmission devices, etc.

2. Material procurement and manufacturing

Material procurement:

Purchase the required materials and components according to the design requirements, ensuring that the quality and specifications of the materials meet the design standards.

Component manufacturing:

Manufacturing of various components of portalkran in the factory, including main beams, support legs, trolleys, lifting devices, etc.

Manufacturing structural components using processes such as cutting, welding, and machining.

Quality Control:

Strict quality control is carried out during the manufacturing process to ensure that the dimensions and performance of each component meet the design requirements.

Conduct necessary non-destructive testing and strength testing.

3. On site preparation

Infrastructure:

On the installation site, carry out basic construction to ensure a solid and flat foundation, and install the track or tire running ground.

Ensure that the space and environment of the installation site are suitable for the installation and operation of the crane.

Transportation and assembly preparation:

Transport the manufactured components to the installation site and prepare the necessary equipment and tools for assembly, such as lifting equipment, welding equipment, etc.

4. Installation

Installation of supporting structures:

First install the support legs and rails to ensure their levelness and alignment.

Then install the main beam and connect it to the support legs to form a gantry structure.

Installation of trolley and lifting device:

Install small cars and lifting devices, including electric motors, transmission devices, lifting equipment, etc.

Ensure that the car can run smoothly on the main beam and the lifting device can move up and down.

Electrical system installation:

Install electrical control system, including control cabinet, cables, sensors, etc.

Ensure the correct connection of the electrical system and conduct preliminary debugging.
