Underhung Crane

Underhung crane, also known as under running overhead crane or underslung crane, is an ideal option for factories that want to free floor space of obstructions since it can be supported from the existing building structure without the needs for support columns. The crane is typically lighter than the top running system and designed for light service or small-capacity applications. Our underhung cranes are capable of handling loads from 1 ton to 10 tons. The work duty is A3.

Features And Benefits of Underhung Bridge Crane

  • Maximizes floor space since it is directly suspended from the ceiling structure or roof structure.
  • Provides excellent side approach
  • Reduces material costs as no runway support columns are needed.

Common Applications of Under Running Crane

Underhung crane is commonly found in fabrication shops, assembly lines, maintenance shops, manufacturing facilities and so on for light to moderate service. It is a good choice for facilities where the building height is inadequate to support a top running overhead crane system. The crane provides less hook height and lifting height than the top running crane since the bridge beam and hoist hang underneath the runway beams.

Underhung Crane Design

Under running crane typically comes in single girder configuration with capacity 1 ton to 10 tons. It uses under running hoist and trolley that run across the bottom flange of the bridge girder. The single girder underhung crane can also be designed in line with European standard, which provides higher performance, longer service life, better appearance, compact structure and minimal maintenance.

We can also design and build the underhung crane system with double girder for higher capacity, but it is impractical and expensive.

Underhung vs. Top Running System: Which One Is Right For You?

There are several factors that can help you determine whether a top running or underhung system is right for your facility and your lifting needs:

  1. Are there existing support columns in your facility, or will you build new engineering columns?
  2. Are there existing runways that the crane can be installed on?
  3. Your required crane specifications, including rated load capacity, lifting height, hook approach.
  4. The overhead room in your facility

You can speak with one of our experts and discuss these information with them. They will assist you to select a crane system that provides proper balance between efficiency, suitability, durability and cost effectiveness.
