INTRODUCTION

What is this?

The BMHN model electric hoist semi-gantry crane is a specialized lifting device that combines an electric hoist with a semi-gantry structure. One leg runs on a ground rail while the other leg runs on a rail mounted on the building column. The CD/MD electric hoist travels along the single main beam, achieving precise lifting and handling of light to medium loads such as machinery parts, tools, raw materials, and assembled components. If your workshop has limited space or building height constraints that cannot accommodate a standard overhead crane, and your lifting needs are under 20 tons, this product is designed for you.

Why choose a semi-gantry crane over a full gantry or overhead crane?

Compared to full gantry or overhead cranes, the BMHN semi-gantry solution offers four core advantages:

First, adapts to confined spaces – utilizes the building column rail on one side, eliminating the need for independent elevated rails on both sides, especially suitable for workshops with insufficient height.

Second, lower investment cost – simplified single girder structure with electric hoist reduces overall cost by 30%-40% compared to full gantry cranes, ideal for budget-limited projects.

Third, faster installation – lighter self-weight with lower foundation requirements, installation and commissioning completed within 7-10 days.

Fourth, easy maintenance – electric hoist design features modular components, quick replacement, and less daily inspection workload.

Break through workshop space limitations with a more economical structure.

What can we do for you?

We understand that every customer has different workshop structures, different capacity requirements, and different working areas. Therefore, we offer flexible customization options: lifting capacity from 1 ton to 20 tons; span from 5 meters to 16 meters; control options of pendant or remote radio; VVVF speed control optional for smooth start/stop. Whether your workshop is old with low clearance or new and spacious, we can match the most suitable span and lifting height.

Unsure? Don't know?

Not sure whether a semi-gantry or a full gantry is more suitable for your workshop? Don't know what lifting capacity you need? No problem. Just tell us: your building column height, your workshop span, and the maximum weight of the objects to be lifted. Our engineers will provide you with an accurate quote and CAD drawings within 24 hours. Click the button below or contact us via WhatsApp/email to get your customized solution.

APPLICATION SCENARIO

[1] Workshop Loading Bays – Handling machinery parts, tools, and light equipment near bay doors with one side wall-mounted, freeing up floor space.

[2] Warehouse Loading/Unloading Areas – Lifting raw materials, finished goods, and assembled components from trucks or storage racks with efficient operation.

[3] Machinery Maintenance Workshops – Servicing engine components, gearboxes, and heavy spare parts where building rails exist and space is limited.

[4] Small Assembly Lines – Moving assembled components between workstations with precise positioning and smooth operation.

[5] Repair and Service Centers – Lifting damaged equipment, vehicle parts, and machinery for repair work in confined workshop environments.

ADVANTAGES

[1] Space-Saving Design – Utilizes existing building column for support on one side, freeing up valuable floor space.

[2] Low Investment Cost – Simplified single girder and electric hoist structure reduces manufacturing and civil costs.

[3] Easy Maintenance – Electric hoist modular design allows quick component replacement and simple daily inspection.

[4] Quiet and Clean Operation – Electric hoist operates smoothly with low noise and no hydraulic oil leakage.

[5] Flexible Control Options – Available with pendant or remote radio control for operator convenience.

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.
