1. Double welding box girder, beam deflection according to DIN/FEM standards.

Steel Material: Standard structural steel similar to Q235B and Q345B.

Trolley rail is made of high-strength hot rolled flat steel (16 Mn).

Epoxy zinc-rich painting with one bottom and two side coatings of 120 μm thickness to achieve long service life, good appearance and high corrosion resistance.

The girder and end beam are connected together by high-strength bolts to ensure the structural strength and precision of the entire crane.

The end beams are equipped with flat wheels or double rim wheels, anti-friction bearings, buffer blocks and derailment preventing end plates.

A maintenance walkway is located on one side of the main girder, consisting of flower pattern plate and 1050 mm handrail.

Both sides of all crane steel plates are pretreated through a pretreatment production line, including sand blasting, primer spraying and primer drying. This eliminates internal stress of the steel plate and increases adhesive force of the steel structure, ensuring good appearance and corrosion protection.

1. Steel plate cutting adopts complete sets of Messer CNC plasma cutting machines from Germany, providing very fast cutting speed, minimal deformation and high precision. Deviation can be controlled within 1 mm, ensuring the raw materials meet high quality industry standards.
2. The main beam welding adopts high-efficiency intelligent welding robots. HNC INDUSTRIES PVT LTD is one of the leading enterprises using this advanced technology. The welding joints inside the main beam adopt advanced MAG welding with Ar + COâ‚‚ mixed protective gas, while the four welding joints outside the main beam adopt automatic submerged-arc fillet welding machines.
3. The welding of the main beam undergoes radiographic inspection and ultrasonic flaw detection for both welding joints and fillet weld positions.
4. The welding of the end beam adopts double-gun gantry submerged arc welding, ensuring high welding quality and stable crane performance.
5. HNC INDUSTRIES PVT LTD adopts steel plate rolling drums and seamless steel tubes. The company has a steel plate rolling drum production and processing line at an industry-leading level. From pre-bending by 1250-ton press machine to edge rolling by three-roller plate roll, the longitudinal and circumferential joints of the drum are welded by an automatic welding center and processed by a heavy-duty CNC horizontal machine tool.
6. The crane wheels and wheel axles are treated by high-efficiency quenching and tempering, effectively eliminating internal stress and ensuring machining precision.

The trolley frame, drum, bogie frame and other large welded structures are treated by annealing in a natural gas annealing furnace to ensure machining accuracy after welding. HNC INDUSTRIES PVT LTD has a car-bottom natural gas annealing furnace with chamber size 10000 mm × 4000 mm × 4000 mm, capable of stress-relieving annealing treatment for trolley frames, drums, bogie frames, balance beams, spreaders and various crane welded structures. Only HNC INDUSTRIES PVT LTD has this capability in Raipur.

1. HNC INDUSTRIES PVT LTD has advanced processing and manufacturing equipment and modern production technology in the crane industry across India. The company continuously improves management and manufacturing processes to ensure high product quality and customer satisfaction.

Overload Protection: In the event of overload, the hoist unit automatically switches off and only the lowering motion remains possible for safe load handling.

Travel Limit Protection: Long and cross travel are controlled by preliminary and final limit switches or a wireless anti-collision device to prevent crane collision.

Anti-Falling Protection: The three-in-one electric motor used in the trolley and crane is equipped with anti-fall protection to prevent accidental dropping.

All crane movements can be immediately switched off by actuating the emergency-off switch at the control station through the main contact.

High-quality, long-life polyurethane buffers are installed at the end of trolley travel and crane travel to prevent over-travelling.

A safety hook latch is used to prevent lifted materials from slipping out of the hook.

An audible and visual alarm device alerts personnel working nearby when the crane is travelling or operating.

A rain cover is provided for the lifting mechanism of outdoor cranes, including protection for the electric cabinet and driving mechanism.

A protective earth conductor is fitted as standard to ensure electrical safety.

A low-voltage protection system protects the crane equipment during voltage drops.

A current overload protection system safeguards electrical components from excessive current.

HNC Industries Private Limited provides advanced overhead cranes in the field of industrial material handling. All overhead cranes are designed according to recognized overhead crane standards. The single girder overhead crane (monorail overhead crane) and double girder overhead crane are engineered with efficient and reliable crane design.

An overhead crane consists of many important components including overhead crane hoists, crane brakes, end trucks, crane trolley, crane hooks, crane kits, pendant controls, crane control systems, signal indicators, crane rails, rail stops, and other essential overhead crane equipment used in modern industrial lifting systems.

HNC Industries Private Limited also provides professional crane installation services.

HNC Industries Private Limited not only supplies overhead cranes but also provides complete overhead crane solutions. We provide overhead bridge crane design, overhead crane manuals, crane drawings, wiring diagrams, electrical diagrams and safety videos before or after delivery. Our technicians supervise the installation according to the provided documentation, and customers can also perform installation themselves based on project requirements.

After installation, our technicians guide the crane load test according to standard overhead crane testing procedures, followed by overhead crane operator training and crane maintenance training. All procedures are supported with crane training videos and training PowerPoint materials to ensure safe and efficient operation.

HNC Industries Private Limited has received multiple recognitions and certifications for different overhead crane types.

For more information about overhead cranes, please refer to the overhead crane attachments, overhead crane PDF documents and crane catalogues to obtain detailed overhead crane specifications and regulations from the download center.

The single girder overhead crane range includes 1 ton, 2 ton, 3 ton, 5 ton, 10 ton, 16 ton and 20 ton overhead cranes.

If you require higher lifting capacity, please check our double girder overhead crane models.
