Under running Overhead cranes

Under running overhead cranes

Is your building too small for a conventional overhead crane?

No ground support for support columns? Are you looking for a solution integrated into the structure of your building for your lifting operations?

Suspended cranes, also known as under running cranes, are specially designed to meet these requirements.

What is an under running crane?

An under running overhead crane is a lifting device where the crane runs on rails attached directly to the ceiling (or to the building structure), unlike conventional overhead cranes which rest on rails laid on a structure.

Technical specifications

Lifting capacity: up to ~ 16 metric tons

Span: up to ~ 25 meters

Lifting height: up to ~ 20 meters

Hoist type: chain or wire rope

Runway: H- or I-beam fixed to building ceiling

Possible configurations :

1. Single girder standard, double girder on request
2. Straight or flush-mounted connection
3. Other capacities, spans and lifting heights available on request

What are the advantages of under running overhead cranes?

1. Ideal when building a self-supporting structure is not an option
2. Generally better lateral approach to the hook
3. Allows hoists to be transferred from one crane to another, or to a monorail, depending on the configuration.

What are the disadvantages of under running overhead cranes?

1. Lifting capacity limited by building structure
2. Span generally smaller than top running overhead cranes
3. More frequent maintenance due to ceiling-mounted rails, which can be subjected to building movements. This can lead to rail misalignment.
