CJ LT1070

1. Basic Positioning The Changjiang LT1070/1 is a 70-ton class truck crane manufactured by Sichuan Changjiang Engineering Crane Co., Ltd. (formerly Terex Changjiang). It is a classic mid-to-large tonnage crane widely used in high-rise construction, bridge engineering, and industrial equipment installation, known for its reliable performance and stable lifting capacity. 2. Core Technical Parameters 表格 Item Specification Max. Rated Lifting Capacity 70 tons (at minimum radius with base boom) Main Boom 5-section elliptical telescopic boom - Min. Length 11.62 m - Max. Length 44.1 m Auxiliary Boom Optional 16 m truss-type auxiliary boom Max. Lifting Height 42.7 m (main boom only); 58 m (main + auxiliary boom) Max. Lifting Moment 2354.4 kN·m (base boom) Outrigger Span 7.8 m (transverse) × 6 m (longitudinal) Power System Dual-engine configuration (chassis + independent upper-structure engine) Gross Vehicle Weight Approx. 50–55 tons Max. Travel Speed Approx. 80 km/h 3. Key Advantages 1. Robust Boom Design The 5-section elliptical main boom offers excellent bending and torsion resistance, ensuring stability during long-boom operations. Full extension to 44.1 m provides a wide operating range for high-altitude and long-distance 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 torque for smooth hoisting, luffing, and slewing actions. 3. Stable & Reliable Performance Large-span outriggers and full-slewing structure enhance anti-overturning capability, adapting to complex construction site terrain. Constant-power variable hydraulic system ensures precise control and smooth compound movements. 4. Proven Industry Heritage Developed with technical collaboration from Terex, combining mature European engineering with domestic manufacturing expertise. Iconic white-gray exterior design and circular "Changjiang" logo make it highly recognizable in the crane market. 4. Typical Applications High-rise construction: Lifting steel structures and precast concrete components Bridge engineering: Erecting bridge girders and installing construction equipment Industrial installation: Positioning heavy machinery, pressure vessels, and production lines Special scenarios: Tower crane assembly/disassembly and wind turbine component handling 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.
