15 Ton Overhead Crane for Hazardous Environment
15 Ton Explosion-Proof Crane for Hazardous Indoor Lifting in Nigeria

Safe, reliable 15-ton crane designed for hazardous indoor environments in Nigeria, featuring low-headroom hoist, dual units, and explosion-proof compliance.

Indoor hazardous lifting environments present unique challenges that standard cranes simply cannot handle. In workshops or industrial areas where flammable gases, dust, or vapors are present, even a small spark can create a serious safety risk. At the same time, these facilities often need to move heavy equipment or materials quickly and efficiently to maintain smooth operations. Balancing safety with productivity is a constant concern.

Explosion-proof cranes play a critical role in these settings. Designed to prevent sparks, contain heat, and operate reliably under hazardous conditions, they allow operators to lift and transport heavy loads without compromising safety. Their sturdy design also ensures long-term durability, reducing downtime and maintenance costs.

To address these challenges, a 15-ton, 13-meter span explosion-proof overhead crane was developed. This crane is specifically designed for indoor hazardous environments:

• Safe lifting in gas- or dust-prone areas, meeting strict Ex II 2 G Ex de IIC T4 standards.
• Dual units capability, allowing simultaneous lifting operations in the same facility.
• Low-headroom design with crab trolley, maximizing available lifting height in confined spaces.
• Integrated runway system, ensuring stable and smooth crane travel across the workshop.

This solution combines safety, practicality, and efficiency, offering a reliable lifting system for hazardous indoor environments.

Project Challenges in Hazardous Indoor Environments

Working in hazardous indoor environments comes with a set of challenges that demand careful planning and specialized equipment. Lifting heavy loads is not as simple as using any overhead crane—there are real risks associated with sparks, flammable gases, and combustible dust. Ensuring safety while maintaining productivity is a delicate balance.

Some of the key challenges include:

• Handling heavy loads safely in flammable or explosive conditions
  Operating in areas with gas, dust, or vapor requires cranes that prevent sparks and are fully explosion-proof. Even small electrical or mechanical failures could lead to accidents, so the equipment must meet strict safety standards.
• Limited headroom or constrained workshop space
  Many industrial facilities have low ceilings or tight layouts. A standard crane could reduce the effective lifting height or interfere with workflow. Designing a low-headroom solution while maximizing lifting capacity is essential.
• Need for continuous, reliable operation without downtime
  Industrial processes cannot afford frequent interruptions. The crane must operate smoothly and consistently, even in tough conditions, to prevent delays and keep operations running efficiently.
• Compliance with strict explosion-proof standards (Ex II 2 G Ex de IIC T4)
  Adhering to certified explosion-proof standards ensures safety and legal compliance. Every electrical and mechanical component needs to meet rigorous testing to operate safely in hazardous environments.

Addressing these challenges requires a solution that is not only technically capable but also practical for everyday industrial use. The next step is designing a crane system that tackles all these issues effectively, without compromising on safety or productivity.

Exproof Crane Requirements for Hazardous Lifting

To tackle hazardous indoor lifting safely and efficiently, the crane needed to meet a clear set of practical requirements. These specifications ensured not only safe operation in flammable or dust-prone areas but also optimized workflow and lifting capacity for the workshop environment.

The main requirements included:

• Safe lifting in gas/dust-prone areas
  Designed to prevent sparks or heat generation, protecting both personnel and equipment.
• Lifting capacity: 15 tons
  Capable of handling heavy loads reliably and safely.
• Crane span: 13 meters
  Covering the full workshop width to enable smooth material handling.
• Crane Lifting Unit: Explosion proof hoist with low headroom design
• Lifting height: 8.95 meters
  Maximizing lifting height despite limited headroom.
• Power supply: 400V, 50Hz, 3 Phase
  Fully compatible with local electrical infrastructure for safe operation.
• Two units for parallel lifting operations
  Allowing simultaneous lifts for increased efficiency and reduced handling time.
• Complete system including runway beams
  Ensuring stability, smooth travel, and seamless integration into the workshop layout.
• Explosion-proof compliance: Ex II 2 G Ex de IIC T4
  All mechanical and electrical components designed to meet strict explosion-proof standards.

Meeting these requirements was essential to deliver a practical, reliable, and safe crane solution that could operate effectively in a hazardous indoor environment while maximizing productivity and minimizing risk.

Project Execution

Delivering a 15-ton explosion-proof crane for hazardous indoor lifting requires careful planning and step-by-step coordination. Each stage of the project was designed to ensure safety, quality, and timely completion.

Key steps in the execution process included:

• Detailed engineering drawings prepared and approved
  Every dimension, lifting specification, and layout detail was verified to match the workshop's requirements and safety standards.
• Fabrication and factory testing, including load and function checks
  The cranes were assembled and tested under real working conditions, ensuring all mechanisms worked reliably before shipment.
• Packaging and shipment to Nigeria with protective measures
  The cranes and runway beams were carefully packed to prevent damage during transit, including reinforced crates and protective coatings for sensitive parts.
• Remote guidance for safe installation and commissioning
  Our engineers supported the local team through every step of installation, ensuring the cranes were set up safely and operated correctly from day one.
