Product Description As a dedicated equipment for heavy hoisting, the used QY70KC Crane has enhanced heavy-load operation performance through special debugging. Its hydraulic hoisting system adopts a dual-circuit design, which can output strong power synchronously, easily handling the hoisting of heavy objects such as wind turbine towers and large bridge components. Wear-resistant bushings are added at the boom joints and sealed to reduce wear and leakage caused by long-term heavy loads. Combined with the upgraded anti-sway algorithm, it can accurately control the swing range of heavy objects. Even in complex working conditions such as wind power sites and cross-river bridges, it can maintain stable and efficient hoisting performance, a core advantage that ordinary medium and small tonnage cranes cannot match.Different from conventional used equipment, this used crane has undergone in-depth renewal of core components: the main winch has replaced the new steel wire rope and performed tension calibration, greatly improving the hoisting speed and load-bearing stability; the slewing bearing has been disassembled and cleaned, then filled with special grease, making the rotation action smoother without lag; the hydraulic oil tank has been thoroughly cleaned and replaced with high-quality filters, effectively avoiding system failures caused by oil contamination. In addition, all key welds of the whole machine have undergone ultrasonic flaw detection to eliminate potential cracking risks, making the used equipment close to the new machine standard in structural strength and operation reliability, and solving customers' concerns about the performance of used equipment.The used QY70KC Crane has added an intelligent operation and maintenance system, which can collect key data such as hydraulic system pressure, boom stress, and engine speed in real time, and display them intuitively through the panel, allowing operators to grasp the equipment status at any time and predict faults in advance. At the same time, the system has a built-in maintenance reminder function, which automatically prompts maintenance items such as filter replacement and grease filling according to the operation time, avoiding component loss caused by missed maintenance. The cab is equipped with a high-definition touch screen, which supports one-click storage of operation parameters. For different hoisting scenarios (such as wind power, bridges), preset parameters can be quickly called, greatly shortening the scenario switching time and improving the overall operation efficiency.
