A Frame Gantry Crane

A frame gantry crane is a common type of gantry crane system used for both indoor and outdoor applications. It is designed with a range of capacities and sizes to meet varied needs of customers. A frame crane can be a significant investment since it is a reliable and versatile material handling equipment to help you improve efficiency and production for your business. The crane can be configured in single girder or double girder design. In addition, a mobile type is available for excellent flexibility and maneuverability.

Types of A Frame Gantry Cranes

  • Single girder crane

With only one girder, the crane requires simpler hoist design, faster installation and easier maintenance. It is commonly used for light duty or moderate applications. It is also very popular for indoor applications where it is not appropriate to install an overhead runway system. The gantry crane can eliminate the need for runway beams and support columns.

Applications of Gantry Crane Equipment

The gantry lifting equipment can be adapted to almost all sorts of applications indoors and outdoors, such as to lift and move a heavy load in workshops, warehouses, workstation, container yards, scrap yards and railroad terminals.

The crane can also be designed with truss structure for use in harsh weather condition, like strong wind. The truss gantry crane requires more maintenance care since there are more solder joints than other types of cranes.

A frame mobile gantry crane is typically used for light fabrication, assembly or maintenance work in workstations, warehouses and garages. It can be moved about your facility easily and freely without installing a track or rail system.

A Frame Gantry Crane Design Considerations

In order to get the right type of crane for your applications, there are a few things you need to consider in the selection of a gantry crane:

  • Gantry design: what gantry will you desire, full gantry, truss gantry, semi-gantry or portable gantry system? Will the crane run on rail, track or wheels?
  • Required crane specifications: what are your requirements for lifting capacity, span, lifting height, lifting speed, travelling speed, hook coverage, etc.
  • Duty cycle: it is critical to select the right duty cycle or service classification, which can help ensure the equipment is strong and durable enough to handle the load and usage requirements.
  • Environmental condition: will the crane be used indoors or outdoors? If the crane is operating outdoors, you should consider the type of paint system to make sure it can withstand corrosion or harsh weather conditions.
  • Power requirements: what type of power delivery do you require, cable reel, diesel generator sets or bare copper slip line? If it is a portable gantry crane system, will it be operating electrically or manually?
  • Other special requirements: do you need additional safety equipment for safe lifting operation, such as anti-collision device, anti-sway device and limit switches.
