Oversee the installation process to ensure it is carried out correctly, safely, and on schedule.
Conduct a thorough commissioning of the crane to verify its functionality and performance, and provide hands-on training for operators.
On-site Training: Offer additional on-site training sessions for operators, maintenance staff, and supervisors, customized to their specific roles and responsibilities.
Provide safety training and best practices for operating and maintaining Zomax cranes to prevent accidents and optimize efficiency.
Post-Installation Support:
Ensure smooth crane operation from the day of installation and conduct follow-up visits immediately after installation.
Address any questions or concerns raised by the customer, whether related to crane performance or operational efficiency.
Provide detailed handover documentation, including equipment manuals, maintenance schedules, and technical support contact information.
Explosion-proof cranes are designed for hazardous environments where flammable gases, vapors, or dust are present. Key features include:
Sealed electrical components and motors to prevent sparks
Flameproof enclosures (Ex d)
Anti-sparking hooks and components
Compliance with ATEX, IECEx, or local hazardous area standards
Explosion-proof cranes are rated for different zones:
Zone 0 / 20: Continuous explosive atmosphere (rarely used for cranes)
Zone 1 / 21: Likely explosive atmosphere occasionally
Zone 2 / 22: Not likely, but possible under abnormal conditions
Calculate the heaviest load, lifting height, and span. Consider:
Single vs. double girder cranes
Frequency of lifting (duty cycle)
Load shape (drums, barrels, chemicals)
Explosion-proof cranes often use Ex motors, explosion-proof hoists, and sealed control panels. Options include:
Pendant control stations with flameproof enclosures
Wireless or radio remote controls designed for hazardous zones
Emergency stop features for high-risk operations
Regular maintenance is crucial:
Check seals and enclosures for damage
Inspect motors and wiring for heat buildup or corrosion
Follow strict documentation procedures for hazardous area maintenance
Selecting a crane with modular components simplifies maintenance without compromising safety.
Explosion-proof cranes often include emergency stop, anti-sway, and load limiters
Operator training for hazardous zones is essential
Choose designs with visual and audible alarms for safe operation
