Explosion-proof overhead cranes

Overhead cranes

 

Explosion proof overhead cranes

 

Some work environments contain flammable gases, such as gasoline vapors or natural gas. Others, like paint booths, present combustible dust or unstable particles suspended in the air. The presence of an ignition source, heat, spark, friction, or electrostatic discharge, can be enough to trigger an explosion.
 
A simple classification error can turn equipment that appears safe on paper into a major risk in the field.
 
This is why we offer explosion-proof overhead cranes and lifting devices, designed and certified according to the strictest standards, including the Canadian CSA standard and ATEX/IECEx directives for explosive environments.

Classification of hazardous locations

Hazardous locations are classified according to the type of danger involved: Class I locations (Zone 0,1,2) involve flammable gases or vapors in sufficient quantities to form explosive atmospheres, while Class II locations (Zone 20,21,22) are characterized by the presence of combustible or electrically conductive dusts. The classification by an expert specifies the location of the equipment in the room, the type of substance and the environment, as well as the maximum surface temperature of the equipment, in order to prevent any risk of self-ignition.
Canada/US: Class I,II division 1,2
Canada/other countries: Zone 0,1,2 or 20,21,22

Explosion-proof Zone

Should we classify according to the division system or the zone system?

In principle, zone and division methods of site distribution offer equivalent levels of safety. However, the Canadian Electrical Code (CE) gives preference to zoning. As indicated in Section 18, new installations in Class I hazardous locations will henceforth be classified according to the zoning system.
For existing installations, the decision to reclassify them under the zoning system is left to the owner. Lifting equipment approved for Class 1 or Class 1, Division 1 is accepted in Zones 1 and 2, while Class 1, Division 2 lifting equipment is only accepted in Zone 2. Refer to articles 18-100 and 18-150 and the table in Appendix J, section J1.2.

classification's determination

Who can determine classification?

The classification of hazardous locations is a complex process requiring in-depth expertise. It is strongly recommended to call on an experienced professional, such as a chemist, to carry out this assessment, rather than to improvise as an expert in this field. So, caution and the involvement of a specialist are essential to guarantee safety and avoid potentially serious consequences. A well-documented hazardous environment analysis process will enable the crane manufacturer to design the most suitable equipment.

Is certification mandatory for equipment and components that are not electrical?


In some cases, equipment or components may appear safe because they are not electrified. Take, for example, an air-powered hoist. At first glance, this equipment presents no spark hazard. However, the friction of certain materials or impacts could generate sparks. In Canada, there are no recognized national standards, or certification programs, for evaluating non-electrical equipment used in flammable environments, although some industries or jurisdictions may impose their own requirements. That said, the expert involved in the case may recommend specific spark-resistant non-electrical components, such as brass wheels, a bronze-coated hook or a stainless steel electrification system.

How much does an explosion-proof overhead crane cost?

The cost of an explosion-proof overhead crane is typically 3 to 4 times higher than that of a standard crane. This difference is due to the use of specialized components designed to withstand explosion risks, and the need to comply with strict manufacturing standards. Each system requires precise wiring, in-shop testing, and a mandatory CSA SPE-1000 inspection in Canada after electrical assembly.

Where to Start?

Choosing an explosion-proof overhead crane can feel overwhelming, especially when strict safety and hazardous zone standards must be met. Here are the recommended steps to launch your project in a structured and efficient way:

 

  1. 1. Consult a process specialist
  2. Before selecting your equipment, it's essential to determine the classification of your hazardous area (class, division, group, auto-ignition temperature). This step directly influences the type of explosion-proof crane required.
  3.  
  4. 2. Assess your lifting requirements
  5. Make sure to gather the following operational data:

  1. Number of lifts per hour

  2. Required lifting height

  3. Maximum load weight

  4. Lifting and travel speeds (if specific speeds are required)

  5. Ambient temperature or other environmental conditions

  1. 3. Communicate with the crane manufacturer
  2. Before reaching out to a manufacturer, prepare the following details:
  1. Your environment’s classification (class, division, group, temperature)
  2. Your operational cycles (frequency and intensity)
  3. Any integration constraints: available clearance, physical space, and safety requirements
You now have a clear overview of the key elements needed to plan a safe and compliant explosion-proof crane project.
