LDPE double hoist single girder crane

Technical Configuration

Technically, the LDPE crane is built around a welded box-section single girder that supports two independent electric wire rope hoists. The standard capacity range spans from 0.5 tons to 20 tons, with a span width from 7.5 meters to 31.5 meters, and lifting heights configurable from 6 meters up to 30 meters. The girder structure is identical to the LDP series, with the critical difference being that the LDP carries a single trolley hoist while the LDPE carries two trolley hoists. Each hoist can be operated independently via its own joystick, or the two can be linked electronically for synchronized movement to lift long workpieces such as steel beams, pipes, or molds. The common cart running mechanism is controlled by a single drive system, and each operator station can independently command the cart travel. Control options include pendant handle control, wireless remote control, or an enclosed cockpit, depending on the buyer’s preference for operator safety and line of sight. The electrical system can be specified with Schneider or Siemens components for reliable performance under continuous duty cycles. Standard safety devices include overload limiters, emergency stop buttons, travel limit switches for both cross-travel and long-travel motions, and anti-collision buffers. Optional features include variable frequency drives for smooth acceleration and deceleration, IP55 protection for outdoor or dusty environments, corrosion-resistant paint systems, and custom end carriages to match existing runway beams. The crane is designed and manufactured in accordance with GB/T 3811 and GB/T 14405 Chinese national standards, and can be engineered to meet FEM, DIN, or CMAA specifications upon request.

This double hoist configuration serves a wide range of industrial applications. In steel mills and metal service centers, it handles long billets, coils, and plates that require two-point suspension to prevent bending or damage. In precast concrete plants, it lifts and flips large molds and heavy panels by coordinating the two hoists in opposite directions. In heavy machinery assembly shops, it positions large gearboxes, engine blocks, and press frames where a single hoist would lack stability. In port and logistics warehouses, it manages oversized cargo crates and machinery skids that exceed the capacity of a standard single hoist. In wind energy and renewable equipment manufacturing, it assists in the assembly of tower sections and nacelle components. The ability to independently lift two separate loads simultaneously also makes it valuable in maintenance depots where multiple small components must be handled concurrently.

Buying directly from Chunhua Crane offers significant advantages in cost, lead time, and customization. As a manufacturer founded in 2003, we provide factory-direct pricing that is typically 30 to 50 percent below equivalent European-branded cranes, while maintaining comparable quality through certified welding procedures and rigorous load testing. All cranes can be supplied with CE certification for European markets or CCC certification for Chinese domestic projects. Our engineering team provides custom design services for non-standard spans, special lifting heights, unusual hoist speeds, or integration with existing plant control systems. We commit to a four-hour response time on initial quotations and technical proposals, allowing project managers to move quickly from specification to budget approval. With sea freight logistics established to over 60 countries across Asia, Africa, the Middle East, Europe, and the Americas, we manage the entire export process including container loading, documentation, and customs clearance support.

The ordering process is straightforward and designed for international buyers. Inquiries can be sent via WhatsApp or email, and within four hours you will receive a detailed quotation along with a preliminary CAD drawing showing the crane dimensions, wheel loads, and runway reaction forces. Upon acceptance, a 30 percent T/T deposit is required to begin production. Standard manufacturing lead time is 30 to 45 days, depending on the complexity of customization and current factory load. After production, the crane is test-run, disassembled, and packed for sea freight. We can arrange optional on-site installation supervision or full turnkey installation by our overseas service partners, quoted separately based on your location. Spare parts kits, including spare hoist motors, brake coils, and limit switches, can be included in the shipment to minimize future downtime.
