Floating portal crane

Weihua portal crane is a large-scale slewing lifting equipment installed on dedicated tracks at port terminals. It adopts a classic and stable four-bar linkage boom system, which ensures that the load maintains a minimal horizontal height variation during luffing (adjusting the operating radius), resulting in very smooth operation.
Specifications
  • Maximum operating radius: 30-45m
  • Minimum operating radius: 8.5-12m
  • Operating radius: 6.5-9.5m
  • Working class: A4-A7
Introduction

Floating cranes, also known as crane ships or floating cranes, typically feature different types of cranes installed on the deck of a square-shaped vessel, equipped with mooring systems and living facilities. Medium and small-sized floating cranes generally use shore power supply. If they are self-propelled, they need to be equipped with a propulsion system. Portal cranes are widely used in ports, terminals, storage yards, and other locations for loading, unloading, and transferring cargo from ships and vehicles. Their design, manufacturing, and inspection comply with advanced domestic and international standards such as DIN, FEM, IEC, AWS, GB, as well as newly promulgated national standards.

Technical Specifications

Applications

Based on the equipment attributes of floating cranes, these products are mainly used in:

  • Marine rescue and salvage: Serving as large-scale offshore lifting operation platforms.
  • Port and terminal construction: For installing large components such as caissons and pile foundations.
  • Offshore wind power engineering: Lifting large components like wind turbine foundations, towers, and blades.
  • Bridge and cross-sea engineering: Participating in offshore lifting of large bridge components like steel box girders.
  • Shipbuilding and repair: Used for hull section assembly, equipment lifting, etc.
