At the Jiuquan Satellite Launch Center, the introduction of space-grade double girder overhead cranes has enabled the creation of a high-precision and highly reliable aerospace equipment support system. Powered by key technologies such as laser anti-sway control and multi-axis synchronous coordination, these cranes effectively address the challenges of vertical lifting for oversized aerospace components, providing robust technical support for China’s launch missions. This project not only accelerates the advancement of crane intelligence and precision but also establishes a new global benchmark for lifting technologies in the aerospace sector.

Jiuquan Satellite Launch Center (JSLC) Overview

Jiuquan Satellite Launch Center (JSLC), founded in 1958, is one of China’s earliest and most important comprehensive rocket and satellite launch facilities. It is located in the Gobi region near Jiuquan, spanning parts of Gansu Province and Inner Mongolia. JSLC serves as a major launch site for scientific satellites, experimental satellites, manned spacecraft, and returnable/recoverable satellites. It hosts the launch and support infrastructure for a wide range of missions, including orbital launches with different inclination angles, and has been a central hub for Chinese crewed and unmanned space missions.

Double Girder Overhead Crane Equipment Overview

At the Jiuquan Satellite Launch Center, the aerospace-dedicated cranes independently developed by Dafang Crane undertake critical tasks such as rocket transfer, hoisting, and inspection. The system adopts a dual-girder structural design, with a rated lifting capacity of several hundred tons (customized per mission needs) and a lifting height of more than 100 meters. It is equipped with a multi-axis synchronous control system and laser anti-sway technology, achieving internationally advanced levels of technical accuracy.

Double Girder Overhead Crane Core Application Scenarios

Rocket Vertical Hoisting

• Task: Vertical assembly of multiple stages of the Long March launch vehicles (each single stage weighing over 40 tons)
• Result: Achieves millimeter-level alignment accuracy (≤2 mm error) through laser positioning and a hydraulic synchronous lifting system, increasing hoisting efficiency by 60%.

Dynamic Equipment Testing

• Task: Simulating rocket vibration conditions during launch (acceleration overload up to 10g)
• Result: With built-in intelligent damping devices, test data deviation is reduced by 85%, and equipment failure rates approach zero.

Operations in Extreme Conditions

• Task: Conducting fairing hoisting operations at −25°C (fairing weight: 12 tons)
• Result: Using low-temperature lubricants and fully enclosed electrical cabinets, operational reliability reaches 99.9%.

Double Girder Overhead Crane Technological Innovations

Automatic Anti-Sway and Positioning System
