Professional Answer: Absolutely. Installation and operation are fully feasible without any risk of colliding with the shaft walls! We have specially customized a “Shield Shaft-Specific Narrow-Profile Crane” featuring an extremely compact body design. The main beam width is only 1.2m, and the overall operational width is controlled within 2.8m. Its small turning radius design achieves a minimum turning radius of just 2.5m, enabling flexible maneuvering within the shield shaft and completing 360° full-range lifting operations. Precision positioning protection: The equipment is equipped with shaft wall collision sensors that continuously monitor the distance to the shaft wall. Upon approaching the safety threshold, it automatically decelerates and triggers an alarm, providing dual safeguards against collisions. Additionally, we will dispatch technicians with specialized measuring equipment to conduct on-site measurements of the shield shaft's diameter, depth, and surrounding obstacles at the shaft opening. Based on these measurements, we will optimize the crane's dimensions and installation plan to ensure perfect adaptation to your confined space.

Professional Answer: Rest assured, our equipment features reinforced designs specifically engineered for subway dust and muddy water conditions, resulting in an extremely low failure rate and fully guaranteed longevity of core components! To address dust and muddy water issues, we implement triple protection: First, the entire machine achieves an IP65 protection rating. Second, critical connections use waterproof sealed joints, and the track is equipped with an automatic cleaning device to prevent dust accumulation from affecting operation. Third, the electrical system incorporates moisture-proof and dehumidifying modules to prevent short circuits caused by muddy water.

Professional Answer: Absolutely! Precision in tube segment handling is our core design focus. Our equipment achieves positioning accuracy of ±2mm, perfectly matching the high-precision demands of tube segment assembly! We also tailor the lifting gear design and positioning parameters to your specific segment dimensions and weight. During on-site commissioning, we conduct repeated tests until your precise lifting requirements are fully met.

Professional Answer: Absolutely guaranteed! We fully understand the urgency of “racing against the clock” in subway construction. We've established a dedicated “fast-track delivery channel” for subway construction cranes to ensure equipment is operational as quickly as possible! Standard subway crane models can be produced and delivered within 15-25 days, while customized models take 30-45 days. Our highly efficient installation team, familiar with underground installation procedures, can complete equipment hoisting into the shaft, installation, and commissioning in just 2-3 days—a 50% improvement over conventional installation efficiency. Upon contract signing, we immediately dispatch technicians for on-site surveys to develop installation plans in advance. Once production is complete, our team proceeds directly to the site for installation, achieving seamless integration of “production-survey-installation.”

Professional Answer: We absolutely guarantee timely after-sales response during peak construction periods and will never delay your schedule! Addressing the metro construction demands of “tight deadlines and zero downtime,” we've developed a “Specialized After-Sales Assurance Plan.”

Professional Answer: The operating difficulty is low. Employees can quickly master the equipment after 1-2 days of training, and we provide full-process complimentary training! Firstly, our equipment operation design is highly tailored to construction scenarios. The standard wireless remote control features clearly labeled buttons with only six core functions: lift, lower, crane left traverse, crane right traverse, trolley left traverse, and trolley right traverse. The logic is simple and intuitive, much like operating a standard remote control. Second, the equipment features a semi-automatic mode. You can preset lifting paths and positioning points. Employees simply press the start button, and the equipment automatically completes the lifting operation, reducing operational complexity.

Professional Answer: Rest assured, our equipment fully meets safety standards for subway corporations and construction departments, with all required compliance certifications in place! We hold enterprise qualification certifications and possess relevant credentials for supplying subway construction equipment, serving as a qualified supplier for multiple subway corporations.

Professional Answer: Absolutely! Our specialized metro construction cranes have served over 50 metro lines nationwide, with equipment performance highly recognized by both contractors and metro operators. If you wish to visit a site, I can arrange a nearby project based on your location and construction phase. You set the timing and itinerary—I’ll accompany you throughout, addressing all questions about metro hoisting operations to ensure you see firsthand and buy with confidence.
