CJ LT1050

The Changjiang 50-ton truck crane (e.g., LT1050/QY50G) is a classic mid-tonnage hydraulic truck crane manufactured by Sichuan Changjiang Engineering Crane Co., Ltd. (formerly Terex Changjiang). It is widely used in urban construction, bridge engineering, and industrial installation, renowned for its reliable performance and cost-effective operation. 2. Core Technical Specifications 表格 Item Specification Max. Rated Lifting Capacity 50 tons (at minimum radius with base boom) Main Boom 5-section box-type telescopic boom - Min. Length ~10.8 m - Max. Length ~41 m Auxiliary Boom Optional 9.2–15 m truss-type auxiliary boom Max. Lifting Height ~40 m (main boom only); ~56–58 m (main + auxiliary boom) Max. Lifting Moment ~1650 kN·m Outrigger Span ~7.2 m (transverse) × 5.6 m (longitudinal) Counterweight ~9.1 tons (fixed for road travel) Gross Vehicle Weight ~42.2–42.7 tons Power System Dual-engine configuration (chassis + independent upper-structure engine) Max. Travel Speed ~75–80 km/h 3. Key Features & Advantages 1. Robust Boom Design The 5-section box-type main boom offers excellent bending and torsion resistance, ensuring stability during long-boom operations. Full extension to 41 meters provides a wide operating range for mid-to-high altitude lifting tasks. 2. Dual-Engine Power System Separate engines for chassis travel and upper-structure lifting operations avoid power interference, improving fuel efficiency and operational reliability. The upper-structure engine (typically Cummins or Weichai) delivers stable low-speed torque for smooth hoisting, luffing, and slewing actions. 3. Stable & Practical Performance Large-span outriggers and full-slewing structure enhance anti-overturning capability, adapting to complex construction site terrain. The fixed counterweight design eliminates the need for disassembly during road transport, improving transfer efficiency. 4. Proven Industry Heritage Developed with technical collaboration from Terex, combining mature European engineering with domestic manufacturing expertise. Iconic yellow-black exterior design and "长" (Chang) character logo make it highly recognizable in the crane market. 4. Typical Applications High-rise construction: Lifting steel structures, precast concrete components, and construction materials Bridge engineering: Erecting bridge girders and installing construction equipment Industrial installation: Positioning heavy machinery, pressure vessels, and production line equipment Municipal engineering: Tower crane assembly/disassembly and urban infrastructure maintenance 5. Brand Background Changjiang (CJ) is a long-established Chinese crane manufacturer with decades of experience in heavy-lift equipment. Formerly a joint venture with Terex, it integrates advanced foreign technology with local production to meet domestic and international construction demands.
