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

Steel Material: Indian equivalent standard structural steel similar to Q235B and Q345B, used for high-strength crane structures.

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

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

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

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 for safe maintenance access.

Manufacturing Process: HNC Industries Private Limited

1. Both sides of all crane steel plates are pretreated through a pretreatment production line, including sand blasting, primer spray and primer drying. This eliminates internal stress of the steel plate and increases adhesive force of the steel structure, ensuring better appearance and corrosion resistance.
2. Steel plate cutting adopts 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 raw materials meet high-quality industry standards.
3. The main beam welding uses high-efficiency intelligent welding robots. HNC Industries Private Limited is one of the leading enterprises adopting this advanced technology. Internal welding joints use MAG welding with Ar + COâ‚‚ mixed protective gas, while the four outer welding joints use automatic submerged-arc fillet welding machines.
4. The welding of the main beam undergoes radiographic inspection and ultrasonic flaw detection to ensure strong welding joints and high structural safety.
5. Welding of the end beam adopts double-gun gantry submerged arc welding, ensuring consistent and stable welding quality for crane performance.
6. HNC Industries Private Limited uses a steel plate rolling drum production line at an industry-leading level. From pre-bending with a 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.
7. The crane wheels and wheel axles are treated through high-efficiency quenching and tempering processes to eliminate internal stress and ensure machining precision.

The trolley frame, drum and bogie frame along with other large welding structures are treated through annealing in a natural gas annealing furnace to ensure machining accuracy after welding. HNC Industries Private Limited 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 welding structures. HNC Industries Private Limited has advanced capability for such processes in the Indian crane manufacturing industry.

1. According to customer requirements, cranes can be equipped with a high-technology anti-swing mechanism, a patented technology applied by HNC Industries Private Limited. This represents an advanced level of crane control technology and improves operational safety and efficiency.
2. HNC Industries Private Limited has advanced processing and manufacturing equipment and modern production technology in the Indian crane industry. The company continuously improves management systems, manufacturing processes and product quality to ensure reliable crane performance and customer satisfaction.

Overhead Crane Safety Features: HNC Industries (Raipur, India)

HNC Industries, a leading EOT and overhead crane manufacturer in Raipur, India, integrates advanced safety systems into every crane to ensure reliable and secure industrial lifting operations.

• Overload Protection: In the event of overload, the hoist unit automatically switches off and only the lowering motion remains possible to ensure safe load handling.
• Travel Limit Protection: Long travel and cross travel are limited by preliminary and final limit switches or by a wireless anti-collision device to prevent crane collision.
• Anti-Falling Protection: The three-in-one electric motor used in the trolley and crane includes anti-falling protection to prevent accidental dropping.
• Emergency Stop System: All crane movements can be immediately switched off by actuating the emergency-off switch at the control station through the main contact.
• Polyurethane Buffer Protection: High-quality long-life polyurethane buffers are installed at the end of trolley travel and crane travel to prevent over-travelling.
• Safety Hook Latch: A safety hook latch is installed to prevent lifted materials from slipping out of the hook.
• Audible & Visual Alarm Device: Alarm systems alert nearby personnel when the crane is operating or moving.
• Rain Cover Protection: Outdoor cranes are equipped with rain covers for the lifting mechanism, electrical cabinet, and driving mechanism.
• Protective Earth Conductor: A protective earth conductor is fitted as standard to ensure electrical safety.
• Low Voltage Protection System: Protects crane equipment from voltage drop or electrical instability.
• Current Overload Protection System: Prevents damage to crane electrical components due to excessive current.
