LD single girder crane

Technical Configuration

The technical configuration of the LD single girder crane is built around a modular design that accommodates a wide range of operational requirements. Standard capacity options span from 0.5 tons to 20 tons, with spans ranging from 7.5 meters to 31.5 meters. Lifting height can be specified between 6 meters and 30 meters, depending on the facility clearance and application needs. The main beam structure consists of steel plate welded into a box section, reinforced with an I-beam profile on which the electric hoist travels. This single girder configuration reduces overall dead weight and building loads compared to double girder designs, making it ideal for facilities with limited headroom. The electric hoist can be selected as a CD1 or MD1 model, with dual-speed lifting available for precise load positioning. For electrical components, buyers may specify standard Chinese electricals or upgrade to Schneider or Siemens contactors, circuit breakers, and control panels to meet specific project requirements or end-user preferences. Control options include pendant handle control with a flexible cable, wireless remote control with a range of up to 100 meters, or a cabin/cockpit mounted control station for dedicated operator positions. Safety devices are integrated as standard, including overload limiters, emergency stop switches, travel limit switches for both cross-travel and long-travel motions, and buffer stops at rail ends. Optional features include variable frequency drives for smooth acceleration and deceleration, anti-collision systems for multi-crane bays, IP55 protection for dusty or humid environments, and explosion-proof configurations for hazardous area classifications.

The LD single girder crane serves a broad cross-section of industries where efficient overhead material movement is essential. In steel mills and metal fabrication shops, these cranes handle raw material coils, finished sections, and die changes with consistent reliability. Warehouses and logistics centers use the LD series for loading and unloading trucks, moving palletized goods, and servicing racking systems. The manufacturing sector deploys these cranes on assembly lines for automotive, machinery, and consumer goods production, where the ability to position components precisely reduces cycle times. In the construction materials industry, precast concrete plants and brick factories rely on LD cranes for mold handling and product stacking. Port and shipyard applications benefit from the crane’s adaptability for container stuffing, machinery maintenance, and cargo sorting under cover. Additionally, the food and beverage industry uses customized versions with stainless steel hoists and washdown-rated electrical enclosures for hygienic processing environments.

Buying from Chunhua Crane delivers a clear cost advantage without compromising on engineering quality. As a direct manufacturer, we offer factory prices that are typically 30 to 50 percent below equivalent European brand cranes, while maintaining compliance with international design standards including GB/T 3811, FEM 1001, DIN 15018, and CMAA 70 specifications. All LD series cranes can be supplied with CE certification for European markets and CCC certification for projects requiring Chinese mandatory approval. Our in-house engineering team provides custom design services for non-standard spans, special lifting heights, unusual building structures, or specific duty cycle requirements. We respond to technical inquiries and provide preliminary CAD drawings within four hours during business hours, allowing buyers to evaluate fit and feasibility quickly. With sea freight logistics established to over 60 countries, we manage the entire export process including proper packing, container loading, and documentation for customs clearance.

The ordering process for an LD single girder crane is straightforward and designed for international buyers. Begin by sending an inquiry via WhatsApp or email with your required capacity, span, lifting height, and preferred control type. Our engineering team will respond within four hours with a detailed quotation and a preliminary CAD layout drawing showing the crane dimensions and runway loads. Once the quotation is accepted, we issue a proforma invoice requiring a 30 percent T/T deposit to initiate production. Manufacturing lead time is typically 30 to 45 days, depending on the complexity of customization and current factory workload. Upon completion, we arrange sea freight delivery to the nearest port in your country, with full packing documentation including a packing list, bill of lading, and certificate of origin. For buyers who require on-site assembly and commissioning, we can arrange for a Chunhua technician to travel to your facility or coordinate with a local service partner to ensure proper installation and operator training.
