The Power to Lift Safely: The 75/20t Explosion-Proof Crane for Your Demanding Petrochemical Facility

In the world of petrochemical engineering, where precision meets immense pressure and safety is the unwavering foundation of every operation, the equipment you choose is critical. It must be more than just powerful; it must be intelligent, resilient, and fundamentally safe. At Dongqi Crane, we engineer lifting solutions that meet this exacting standard. Our Qb Series 75/20t Explosion-Proof Overhead Bridge Crane is not just a tool—it is a dedicated safety system designed to elevate productivity while guarding your most valuable assets: your people, your facility, and your operational continuity.

Engineered for the Hazardous Environment

We understand the unique challenges you face daily. In areas where flammable gases, vapors, or combustible dusts may be present, ordinary equipment introduces unacceptable risk. Our explosion-proof crane is meticulously built from the ground up to eliminate ignition sources and perform reliably in these demanding conditions.

The core of its design lies in the complete protection of every electrical component. Motors, control panels, limit switches, and even the pendant station are housed within specialized, rugged enclosures. These enclosures are engineered to contain any potential internal spark or overheating, preventing it from reaching the external atmosphere. Furthermore, critical mechanical parts are designed with non-sparking materials to prevent hazards during operation. This holistic approach ensures that your lifting operations contribute to a safer workplace, aligning with the strictest international safety protocols, including ATEX directives.

Robust Performance, Unmatched Versatility

With a primary hook capacity of 75 tons and a secondary hook of 20 tons, this crane delivers the strength and flexibility required for the full scope of petrochemical plant activities. The main hook handles your most critical tasks: installing or maintaining heavy reactors, columns, heat exchangers, and large vessel sections. The auxiliary hook provides perfect support for simultaneous, lighter lifts or precision handling of components, tools, and machinery, streamlining complex maintenance procedures and reducing operational downtime.

Every aspect of its performance is tuned for control and reliability. The advanced variable frequency drive (VFD) control system ensures exceptionally smooth acceleration and deceleration. This means precise, gentle handling of sensitive or unbalanced loads, protecting both your cargo and your infrastructure from stress and shock. You can choose between a convenient, sealed pendant control or a remote-operated cabin, providing flexibility based on your specific workflow and safety zone requirements.

A Seal of Trust: CE Certification and Compliance

When we say safety is built-in, we provide the proof. Our 75/20t Explosion-Proof Crane carries the CE mark, a testament to its compliance with the rigorous health, safety, and environmental protection standards of the European Union. This certification encompasses both the Machinery Directive for overall safety and the critical ATEX Directive for equipment in explosive atmospheres.

For you, this translates into absolute confidence. It verifies that an independent assessment has validated the crane’s design and construction. It simplifies your own compliance efforts and provides documented assurance to regulators, insurers, and stakeholders that you have invested in a world-class, safety-focused solution. It is our promise, formalized, that the product meets the highest thresholds of engineering excellence.
