The main goal is to solve problems that off-the-shelf cranes cannot handle—complex working conditions, unusual site layouts, or specialized functional demands. Custom cranes are widely used in mining, metallurgy, infrastructure, wind power, ports, and other heavy industries. As operating conditions grow more complex and lifting needs become more diverse, standard equipment increasingly shows poor fit and limited flexibility. As a result, more companies choose to customize their cranes based on actual operational needs. ## Custom lifting equipment is typically required in the following situations: - Dimensional mismatch: Standard products have fixed span, lifting height, and wheel dimensions that do not fit the existing workshop or site. Examples include non-standard span buildings and lifting needs in confined spaces. - Special operating environments: High-temperature workshops, flammable or explosive dust areas, and heavy-duty high-frequency operations require targeted adjustments to materials, structure, and protection. Steel and metallurgy sites need heat-resistant wheels and thermal insulation; chemical sites need explosion-proof electrical components. - Special functional requirements: Sectors such as wind power, tunneling, and ports need custom structures, additional devices, or performance parameters. For example, wind-power installation uses a truck crane with a compact body and strong lifting capacity. - Extra-heavy lifting needs: Cranes above 250 tonnes are inherently custom products. They serve only niche fields such as nuclear power, wind energy, and water conservancy, where demand is small but technical requirements are high. ## What Can Be Customized on a Crane? ### 1. Structural Dimensions This is the most common type of customization. The span, lifting height, travel length, and wheel parameters are adjusted to the actual site, avoiding the structural stress imbalance, rail gnawing, and uneven wear that come with modifying the installation base. For example, a standard double-girder overhead crane comes in fixed span values; if the workshop needs a non-standard span, the crane must be custom-built. ### 2. Working-Condition Adaptation Materials and processes are tuned to the operating environment: - Normal-temperature workshops can use cost-effective 40Cr or 45# forged steel wheels. - Sintering bays with residual heat should use 35CrMo alloy steel. - Metallurgy cranes under long-term high-temperature baking use molybdenum-containing 42CrMo chrome-molybdenum alloy steel, which maintains hot strength and prevents strength degradation at high temperatures. ### 3. Functional and Scenario Customization Different industries require dedicated configurations: Metallurgy: Equipped with heat-resistant insulation and dual braking systems for 24-hour continuous heavy-duty operation; service life is over 35% longer than standard models. Chemical: All electrical components meet national explosion-proof standards for safe operation in flammable and explosive environments. Companies in oil and gas processing, coal chemical, electroplating, and dust processing face flammable, explosive, and highly corrosive conditions. Their lifting equipment must carry explosion-proof and anti-corrosion certifications. Non-compliant equipment can easily cause safety accidents. These sites also demand extremely fast emergency response—any failure requires immediate repair to avoid larger safety hazards and production losses. Wind power: The body is shortened for better access on narrow sites while retaining heavy-lift capacity on a short boom. A 180-tonne-class chassis can lift 105 tonnes. Low-headroom workshops: A custom low-headroom structure increases lifting height without modifying the building structure, suitable for large workpieces. ## Typical Custom Crane Process Step 1： Requirements discussion: Tell the manufacturer the detailed operating conditions, including ambient temperature, lifting capacity, frequency of use, and special functional needs. Step 2：Parameter submission: Confirm and provide the core parameters—lifting capacity, span, lifting height, and travel length. The manufacturer then provides a proposal and quotation. Step 3：Proposal confirmation: Compare configurations from different manufacturers and select based on technical capability and after-sales service. Once confirmed, production begins. Step 4：Delivery and service: A qualified manufacturer provides complete compliance documentation, installation, maintenance, and annual inspection support. Some offer a full one-stop service to reduce coordination costs. ## Which Manufacturers in China Build Custom Cranes? Major Chinese crane manufacturers now have mature customization capabilities. In terms of tonnage coverage, everything from small units to 500-plus-tonne port cranes can be non-standard customized, meeting the special needs of most industrial and infrastructure scenarios. The key to delivering a custom crane lies in hard engineering capability. ## Core Advantages of Yuzhong Custom Cranes ## 48 Years of Manufacturing—Built to Spec, Not Forced from a Catalog Yuzhong has focused on crane R&D and manufacturing for 48 years. From 0.5-tonne European-style single-girder cranes to 500-tonne MG-series gantry cranes, from explosion-proof double-girder units to container spreaders, every piece is independently designed around the customer's operating parameters. Custom drawings are available within 24 hours; standard models are never forced onto non-standard requirements. ### Global First-Tier Core Components Motors are from Siemens, bearings from SKF. The gearbox uses Yuzhong's self-developed C-type structure (wire-rope hoists cover 0.5–50 tonnes). No downgrading of critical components. The electrical system supports Siemens, Schneider, and other brands, ensuring long-term reliability and spare-parts availability. ### Corrosion and Protection for Extreme Environments C5-M marine-grade anti-corrosion coating is available as a standard option, with a three-coat total film thickness of 240 µm. It handles high-salt environments such as coastal ports and offshore platforms. The explosion-proof series holds ATEX/IECEx certification, covering Zones 1/2 and 21/22. Outdoor motors come standard with IP66 protection and anti-condensation heaters, running reliably from -40 °C extreme cold to high-temperature, high-humidity conditions. ## Full Certifications, Exported to 120+ Countries Yuzhong is certified under ISO 9001 quality management, ISO 14001 environmental management, and ISO 45001 occupational health and safety. Products comply with FEM, ASME, and CE standards. The company has exported to more than 120 countries and regions, serving benchmark projects across petrochemical, mining, port, railway, pharmaceutical, and defense industries. ## Full-Lifecycle Service Response From design and manufacturing through installation, commissioning, and ongoing maintenance, Yuzhong provides full-lifecycle technical support. 24-hour technical response, on-site installation guidance, periodic inspections, and spare-parts inventory ensure customers have continuous after-sales backing after equipment goes into service.
