Overhead cranes

 

 

Overhead cranes are ideal for lifting and moving heavy loads in complete safety.

Premium helps you configure your crane

When it comes to lifting, the possibilities are endless!
That’s why there are different types of configurations; top-running, under-running, single-girder, double-girder, or even custom-built crane.
Your choice will depend on several factors, including the application and the working environment.
 
So, how do you choose? Where do you start?

top running overhead cranes

Top running overhead crane

The top running overhead craine is mounted on rails. It is available in a single girder version for loads up to 16 tons, while the double girder version offers higher lifting capacity and greater outreach.

Wall-mounted overhead crane

Groupe Industriel Premium also offers wall-mounted overhead cranes. A wall-mounted overhead crane is a lifting device attached directly to a wall in your building. So, unlike conventional overhead or suspended cranes, it doesn't require a self-supporting structure on the floor, or rails on the ceiling.

Overhead cranes by environment

Overhead cranes can be used in a variety of environments, such as indoor buildings, unheated garages, outdoor spaces, as well as explosion-proof, dusty, high-temperature or corrosive environments. Each type of environment requires specific adaptations to ensure safe and efficient lifting operations.

Overhead cranes by application

Overhead cranes are used for a variety of industrial applications, including feeding machines such as cutting tables and CNC machines, loading and unloading materials onto trailers, assembling machinery and metal structures, servicing mobile or fixed equipment, and storing materials such as steel, wood and glass.

Where to Start

Before selecting an overhead crane (freestanding, ceiling-mounted, single- or double-girder), make sure to clarify these key elements:
 
  1.  Your application
    Define the main use (maintenance, production, loading, etc.), the type of loads (weight, dimensions, rotation, tandem lifting), and how often the crane will be used.

  2.  Your environment
    Will the installation be indoors or outdoors? Is there an existing structure, or will one need to be built? What are the available dimensions and potential obstacles?

  3.  Key technical data
    Prepare your desired lifting capacity and height, building layout (if available), project timeline, power supply, and any special constraints.

Frequently asked questions

01.
Who supplies the lifting accessories for my overhead crane?
      A : Lifting accessories are essential for safe crane operation. Their selection depends on several criteria: the nature of the load, the operating environment and current safety requirements. Depending on your application, you may need slings, clamps, magnets, suction pads or spreader bars. Each situation requires a specific solution.

Premium Industrial Group neither manufactures nor supplies these accessories. To guarantee reliable and perfectly adapted solutions, we refer you to specialized suppliers.

Furthermore, if you plan to use electrically or pneumatically powered accessories, integration with the crane control system will be necessary. For example, this may involve installing a cable reel or adding additional buttons to the remote control. We'll be happy to advise you on the best practices and ensure optimum coordination when configuring your overhead crane.
02.
What's the difference between a girder crane and a box girder crane?

  A : Girder overhead crane : Uses one or two less H or I beams, less expensive, for spans generally under 55 ft (16 m). Lifting capacity up to 16 tons in single version and 25 tons in double version.

Box girder overhead crane : Composed of an assembly of plates, offering greater resistance to torsion and deflection, more costly, single or double box girder possible, lifting capacity up to 200 tons and more, for spans generally over 65 feet (20 m).

Overlap zone : Between 55 and 65 feet, both configurations are often possible. A girder crane will be a little “softer”, as standards allow a lower deflection (L/600), whereas a box crane requires more rigidity (L/888). Your application and lifting speed will be criteria to check. Lifting and travel speeds, or sudden stop-start movements (jug), will have an effect on beam oscillation.

 To learn more, consult the article :  Girder vs. Box girder. Which one to choose?

03.
Why are overhead cranes yellow?
     A : Overhead cranes are usually painted yellow to improve visibility and safety in the workplace. Yellow is a color associated with caution and is frequently used to indicate potentially dangerous areas or equipment. It helps to quickly identify the crane's position and movements. That said, the color can be adapted to suit your preferences: we offer the option of customizing the paintwork, adding your logo or using your corporate colors on request.
04.
What's the difference between an overhead crane and a hoist?
     A : Overhead crane : It's a complete lifting device consisting of a girder equipped with wheels (end carriages) running on rails. It also includes a hoist to lift loads.

Hoist : It's a lifting mechanism that can operate independently or be integrated into different lifting devices (overhead crane, gantry crane, jib crane or monorail). As a result, it can only be used to raise or lower a load.
05.
Is it mandatory for an overhead crane to be fitted with an emergency stop?

     A :  CSA C22.2 No33 2019 of the Canadian Electrical Code, Part 1, which is mandatory in Quebec, reads as follows: "In the case of a multi-motor overhead crane, there must be a main contactor to simultaneously de-energize all conductors supplying the current required for the overhead crane's movements. The contactor must be operated by means of a stop-reset control located near the overhead crane operator's control station."

It's important to note that the red button often referred to as an emergency stop button on your overhead crane control is technically called a stop-reset control by electrical designers.

A stop-reset control is therefore mandatory on the following equipment :

 

  • Overhead crane with electric hoist and motorized cart and/or motorized overhead crane
  • Jib crane with electric hoist and motorized cart and/or motorized rotation
  • Monorail with electric hoist and motorized cart
  • Gantry crane with electric hoist and motorized cart and/or motorized travel.

Their ability to listen to our specific needs has been a major strength. They have always responded quickly and efficiently, especially in emergency situations, which has greatly contributed to the continuity and success of our operations. I highly recommend Groupe Industriel Premium to any company looking for a reliable, structured, and responsive partner. Their professionalism and commitment to quality and safety make them a model in the industry.
