Frequently Asked Questions

Q: What safety standards do your cranes comply with?
A: Our cranes are designed in accordance with major international standards, including ISO 4301 for classification, ISO 12480 for safe use, and IEC 60204-32 for electrical installations. We can also customize equipment to meet specific local regulations or project requirements.

Q: Can you provide cranes for explosion-proof environments?
A: Yes, we offer explosion-proof crane and hoist solutions designed for hazardous areas, such as chemical plants, oil & gas facilities, and paint shops. These systems feature specialized components and sealing to ensure safe operation in potentially explosive atmospheres.

Q: What is the typical lead time for a custom crane?
A: Lead times vary depending on the complexity and specifications of the crane. Generally, a standard custom overhead crane can be delivered within 8 to 12 weeks after design approval. We work closely with clients to establish a clear project timeline.

Q: Do you offer installation and after-sales service?
A: Absolutely. Our services include professional installation, on-site commissioning, and comprehensive training for your operators and maintenance staff. We also provide a full range of spare parts and offer service contracts for regular maintenance and inspections.

Q: What is the maximum lifting capacity you can provide?
A: Our standard overhead cranes range from 5 tons to 150 tons, and our gantry cranes can be engineered for capacities up to 300 tons for special applications. For requirements beyond this, please contact us to discuss a custom engineering solution.

Q: Can your cranes be integrated with existing automation systems?
A: Yes, our cranes can be equipped with advanced control systems, including remote controls, semi-automatic features, and full integration with warehouse management systems (WMS) or PLC-based automation. We ensure seamless communication and control for your specific process.

Q: What are the power supply options for your cranes?
A: Our cranes are typically designed for standard three-phase power supplies, such as 380V/50Hz or 480V/60Hz. We can also engineer systems for other voltages and frequencies to match your facility's electrical infrastructure.

Q: How do you ensure the quality and reliability of your products?
A: We adhere to a strict quality management system throughout the design and manufacturing process. Each crane undergoes rigorous testing, including load testing and functional checks, before shipment to ensure it meets our high standards and your specifications.

Q: Do you provide cranes for outdoor applications?
A: Yes, we offer gantry cranes and outdoor overhead cranes designed to withstand various weather conditions. These units feature protective coatings, sealed electrical enclosures, and robust construction to ensure reliable operation in outdoor environments.

Q: Can you help with the design of a crane runway or supporting structure?
A: While our primary focus is on the crane itself, our engineering team can provide general guidance and preliminary recommendations for runway beams and support structures. For detailed civil and structural engineering, we typically recommend coordinating with a licensed structural engineer.

Operating Conditions by Heating Plant Zone

A: Central heating plants and thermal stations consist of four core zones—boiler house, pipe network, heat exchange station, and coal/ash yard—each with distinctly different lifting requirements, ranging from high-temperature dust-laden environments to humid, corrosive conditions. The boiler house (where economizers, dust collectors, and water-wall panels are serviced or replaced) demands the highest lifting capacities in the plant: boiler drums weigh 20–50t and economizer modules 10–30t. For this zone, we recommend a QD-type double-girder bridge crane (16–50t, span 22–36m, work duty A5–A6) fitted with high-temperature-resistant lifting spreaders (operating ambient temperature 60–80°C, with localized peaks up to 120°C) and an operator cab with air conditioning and double-pane insulated glass. In the pipe network zone (pre-insulated pipe laying, valve and compensator installation), an LD-type single-girder electric hoist crane (5–16t) or a mobile gantry crane with pipe-specific spreaders is recommended. The heat exchange station (plate heat exchangers, circulation pumps) involves individual components weighing 2–10t—here, a stainless steel anti-corrosion electric hoist on a hot-dip galvanized rail with an IP55-rated electrical control box is the right fit given the high humidity. The coal/ash yard (conveyor belts, coal bunkers, ash handling) has high dust concentrations (10–20mg/m³); we recommend an overhead crane with grab (10–20t, work duty A6–A7) equipped with a dust-proof motor (IP65) and a sealed, positive-pressure operator cab. Kelude Heavy Industry supplies complete lifting systems for central heating plants, covering everything from large-tonnage bridge cranes in the boiler house to anti-corrosion hoists in the heat exchange station.
