Overhead cranes (also known as bridge cranes) are specialized mechanical equipment that conform to international standards (ISO/FEM). They are typically installed in indoor environments such as factory workshops and warehouses. Bridge cranes consist of five main components:main beam, end beam, electric hoist (trolley), track system, and control system. Based on structural design and functional characteristics, bridge cranes can be mainly classified into the following types:

♦ Single Girder Overhead Crane
♦ Double Girder Overhead Crane
♦ Underslung Crane
♦ Free standing Bridge Crane
…….

When the available space in a factory is inadequate for the installation of a gantry crane or bridge crane, or when lifting operations with a rated load not exceeding 10 tons are required within a limited area, a JIB crane serves as an optimal solution. Through remote control operation, the jib crane enables horizontal rotation of the boom (ranging from 180° to 360°), thereby covering the necessary material handling zones. 

According to different operating conditions, jib cranes are categorized into the following types:
♦ Free Standing Jib Crane
♦ Movable Jib Crane
♦ FEM Standard Jib Crane
♦ Wall-Mounted Jib Crane

Gantry cranes are typically installed in outdoor environments and are widely used in cargo handling operations in container yards, precast concrete mixing plants, and factories. Depending on different usage scenarios and functional requirements, gantry cranes can be mainly classified into the following types:

♦ Single Girder Gantry Crane
♦ Double Girder Gantry Crane
♦ Semi Gantry Crane
♦ Portable Gantry Crane
♦ Aluminum Gantry Crane

Marine Crane is a kind of lifting equipment specifically used for ships, offshore platforms and port operations. Due to its complex working environment and the need to adapt to special Marine conditions such as wind and waves, corrosion, and hull swaying, it has higher design requirements compared to industrial cranes and must be certified by classification societies to ensure safety and reliability.

Marine cranes are mainly classified into the following types:

♦ Foldable Knuckle Boom Crane
♦ Telescopic Boom Crane
♦ Marine Davit Crane
