INTRODUCTION

The low headroom explosion‑proof electric hoist combines compact, space‑saving design with certified safety for hazardous environments. It features an ultra‑low profile body, Ex‑rated motor and electrical components, and spark‑proof mechanical parts. Lifting capacity ranges from 0.5t to 10t, with lift heights up to 20m. This hoist is ideal for applications where both vertical space is limited and explosive gases or dust (Zone 1, Zone 2, or dust Ex zones) are present, such as petrochemical, pharmaceutical, and grain processing facilities.

APPLICATION SCENARIO

[1] Petrochemical plants – Lifting pumps, valves, and small reactors in low‑clearance Ex areas.

[2] Paint and coating workshops – Handling flammable material containers under low ceilings.

[3] Pharmaceutical production – Moving solvent drums in Ex‑classified clean rooms with height limits.

[4] Grain silos and flour mills – Operating in dust‑explosion zones where headroom is restricted.

[5] Oil refineries – Maintenance lifting in congested pipe‑rack areas with Ex requirements.

ADVANTAGES

[1] Low headroom + Ex safety – Gains 200‑400mm extra lifting height compared to standard Ex hoists.

[2] Certified explosion protection – ATEX/IECEx/GB Ex compliant for gas and dust environments.

[3] Spark‑proof construction – Bronze or stainless steel limit switch contacts, anti‑static coating.

[4] Compact and lightweight – Reduces crane dead weight, ideal for retrofitting low buildings.

[5] Reliable and low maintenance – Sealed Ex enclosures and long‑life wire rope.

Six core advantages

Full Scenario Coverage

Nucleon covers over 20 product categories including ladle cranes, multi-purpose cranes, intelligent cranes, overhead/portal cranes, RTG, RMG, deck cranes, portal cranes, girder launchers, yacht cranes, KBK, and jib cranes. From steel smelting to port handling, bridge construction to ship equipment, Nucleon provides one-stop lifting solutions. Whether standard models or extreme-condition customizations, Nucleon possesses mature technical expertise and proven track records, saving customers from dealing with multiple suppliers.

Military-Grade Quality Standards

We use high-strength steel from Baosteel/Ansteel for key structural components, with 100% NDT inspection and one-clamp CNC gantry machining. Every machine undergoes 120% dynamic load and 125% static load tests before delivery, with continuous operation verification under extreme conditions. Even in 24/7 continuous casting plants, -40°C arctic ports, or high-temperature humid ship cabins, our cranes maintain millimeter-level precision and zero-drift stability—quality that stands the test of time.

Extended Longevity & Low Maintenance Cost

Our main girders are FEA-optimized and double-submerged arc welded, with a design life of ≥30 years. Key bearings are lifetime lubrication-free, and hardened travel wheels extend wear cycles by 3 times. Core components feature modular quick-change interfaces with spare parts commonality exceeding 80%. Annual maintenance costs are reduced by 40%~60%, saving millions in lifecycle operating expenses — truly "invest once, benefit long-term."

Energy Efficiency Leader

Our entire series comes standard with IE5 permanent magnet synchronous motors + energy feedback VFD drives, achieving 25%~35% comprehensive energy savings. Single-motor operation under light loads and adaptive speed control reduce electrical waste by over 30%. High-strength steel lightweight design cuts deadweight by 15%~20%, lowering workshop load requirements. A single ladle crane station saves over RMB 150,000 in electricity costs annually, helping customers achieve green and low-carbon production.

Ultimate Safety Redundancy Design

Our hoisting mechanism comes standard with dual brakes + mechanical overspeed switch + triple limit switches, featuring multiple redundant interlocks to prevent load dropping and over-traveling. Large products use box girder torsion-resistant structures, remaining stable even in level 8 gusty winds. Optional intelligent safety monitoring systems detect anomalies in load, skew, wind speed, etc., with automatic alarms and shutdowns. Overall safety redundancy coefficient > 2.0, maintaining zero crane safety incidents for many consecutive years.

Deep Customization & Full Lifecycle Service

We provide complete front-end support from site survey and mechanical simulation to civil review, delivering custom drawings within 2 weeks, with non-standard lead times only 5~7 days longer than standard products. We establish lifelong digital dossiers for customers, warning of end-of-life components 3 months in advance. Our full lifecycle services cover installation training, regular inspections, and remote O&M. With customer repeat purchase rates exceeding 85% for five consecutive years, we are a trustworthy long-term partner.
