Top running single girder crane: the crane is ideal for light duty to medium service with capacity up to 20 tons. It is commonly found in light manufacturing, machine shops, warehouses, maintenance and repair shops and light assembly line. The single girder crane typically utilizes an underhung trolley and hoist.

Why Do You Use A Top Running Overhead Crane System?

  • Top running crane rides on rails on top of the runway beams, thus providing more lifting height for buildings with limited headroom.
  • The crane can be built with capacities of anywhere from 1 ton to over 400 tons, which is ideal for handling extremely heavy loads. It can also accommodate wider spans.
  • The installation and maintenance of the crane is much easier than an underhung crane.
  • The crane offers durable performance and excellent safety.

Top Running & Under Running System, Which One Do You Need?

There are several factors that can help you determine whether a top running or underhung crane system will best fit your facility and your lifting needs:

  1. Can you utilize the existing support structure or will you build a new support structure?
  2. Are there preexisting runways in your facility?
  3. The design and layout of your facility and its ceiling height
  4. Your lifting requirements, such as load capacity, lifting height and hook approach
  5. How important is free and clear floor space?

If higher capacity, higher lifting height and more overhead room are required, a top running overhead crane system is the best option. For any questions, contact us today and we can help you select the most suitable crane system for your applications.
