Crane QY40K5D_1, four-bridge chassis, 45m main boom, 54m longest boom, maximum lifting weight of 45m full boom is 8.9t. The telescopic cylinder is strengthened synchronously, the slewing support base is strengthened, the large-span two-stage outrigger is upgraded, the steel wire rope material of 50t specification, the 340 horsepower engine, the off-road four-bridge special G-type chassis, the counterweight is increased...

In order to ensure the safety of hoisting, QY40K5D_1 uses the industry's 50t φ18 diameter wire rope configuration, which is higher than the standard design, and reserves sufficient safety factors to ensure the product performance to the extreme; upgrade the sinking H-shaped double-section outrigger to ensure stable operation The performance has been greatly improved. Not only the lateral span of the outriggers has reached the industry's largest 7.35m, but also the lower-mounted front outriggers are designed with anti-deformation structure, which prevents shaking and avoiding "inverted eight" during operation, and the long-distance suspension is more stable.

XCMG crane QY40K5D_1, an off-road chassis that meets the requirements of category G driving, compact 2.65m wide, and does not need to be equipped with front safety bars, the cab approach angle is 20°, and the passability is better; 251KW engine, the strongest power in its class, low speed The climbing performance and high-speed transition performance are stronger.

QY40K5D_1 optimizes the design of weight density and volume to fully utilize the width of the vehicle. The space under the weight is more than 500mm, leaving enough space for the sleepers or other tools for hoisting operations, which is convenient to use and reduces preparation time for operations.
