The RC-A11-II from Chengdu Recen Technology Co., Ltd. is an integrated load moment indicator with anti-collision and zone protection, designed for tower crane groups operating in congested construction environments. The system uses full-touch operation and an ARM-based architecture for higher integration and more precise data acquisition than conventional indicator systems. It displays real-time working states both locally on the tower crane and remotely via online computer access, giving site managers visibility across an entire crane fleet.
The system addresses interference at two levels: at the same height, it auto-detects and resolves conflicts within the slewing radius; at different heights, it prevents collisions between a higher hook block and lower slewing mechanisms. It supports up to 10 programmable protection zones, which can be used to prohibit crane operation over sensitive areas such as power lines, schools, highways, and adjacent buildings. This zone programming allows contractors to maximise the working envelope of each crane while maintaining safety margins.
The RC-A11-II suits contractors managing multiple tower cranes on urban high-rise sites, infrastructure projects with overhead restrictions, and rental fleets where operators change frequently. Buyers should confirm whether the system integrates with their existing crane models and telemetry protocols, and whether remote monitoring requires proprietary software or accepts standard data formats. The supplier is based in Longquanyi District, Chengdu City, Sichuan Province, China.

Chengdu Recen Technology Co., Ltd. is located at No.1824, Block 3 Paris International, Longquanyi District, Chengdu City, Sichuan Province, 610000, China. The company holds a harbor trust tier on the marketplace, with a recorded response rate of 0.00% and no logged average response hours, which suggests buyers should allow for possible delays in initial communication and may need to follow up proactively.
The supplier specialises in tower crane safety systems, specifically the RC-A11-II integrated platform that combines load moment indication, anti-collision logic, and zone protection with remote monitoring. The product description indicates engineering focus on ARM-based hardware and touch interfaces rather than legacy button-panel designs. Buyers should verify directly with the supplier what crane makes and models the RC-A11-II supports, whether installation requires certified technicians, and what training or documentation accompanies the system.

Before ordering, verify that the RC-A11-II is compatible with your tower crane make, model year, and control voltage, as retrofitting safety systems to older cranes often requires adapter harnesses or software variants. Confirm whether the supplier provides installation supervision or relies on local technicians, and request documentation in your preferred language. Ask for references from projects with similar crane density and site complexity to yours.
Logistics from Chengdu, Sichuan Province, typically involve inland transport to Shanghai or Shenzhen ports for sea freight, with transit to most destinations taking 20-35 days depending on the receiving port. Buyers should confirm Incoterms with the supplier, whether EXW Chengdu or FOB/CIF terms are offered, and who arranges export customs clearance. Payment terms, accepted currencies, and whether the supplier offers letter-of-credit or advance-payment options should be clarified before contract finalisation.
Quality checks on arrival should include physical inspection of the display unit for damage from vibration during transit, verification that all sensors and cables match the packing list, and power-on testing of the touch interface. Request that the supplier pre-load a test protection zone so you can verify alarm triggering and interlock response before site installation. Retain all shipping documents for warranty claims, and confirm the warranty period, scope, and whether on-site technical support is included or charged separately.
