Fuwa QUY50A

The Fuwa QUY50A crawler crane offers a maximum lifting capacity of 50 tonnes, making it ideal for general construction, utility work, and other medium-duty applications. This crane is equipped with a flexible main boom configuration that can extend from 13 to 52 meters. Additionally, the fixed jib extends from 9.15 to 15.25 meters, allowing for a combined reach of 67.25 meters when both the boom and jib are used together. The QUY50A is well-suited for projects requiring moderate height and lifting versatility.

Powered by a D6114ZG2B diesel engine producing 128 kW at 2000 rpm, the QUY50A provides efficient power for its hydraulic system, which includes main and auxiliary winches driven by hydraulic plunger motors. These winches achieve hoisting and lowering speeds of up to 70 m/min on high speed and 35 m/min on low speed using a 20 mm diameter wire rope. The boom hoist operates at a speed of 45 m/min, allowing for precise control over boom positioning. The crane has a swing speed of 2.7 rpm and a travel speed of 1.1 km/h, enhancing its maneuverability on job sites.

The QUY50A’s undercarriage is designed for stability and mobility, with 118 track shoes per side and a track width of 760 mm. It can handle a gradeability of 40%, enabling it to operate effectively on slopes and uneven terrain. The ground bearing pressure is 0.069 MPa, which supports stability during lifts while minimizing impact on softer ground surfaces. The crane’s counterweight totals 16 tonnes, providing additional stability for safe operation.

This crane includes essential safety features, such as hook and boom over-hoist prevention devices, a moment limiter for load monitoring, and an emergency brake system for the winches. The cab is equipped with a comfortable seat, air conditioning, and large electronic monitors, providing a secure and ergonomic environment for the operator. The cab also includes a fire extinguisher and an adjustable chair, ensuring comfort during prolonged operations.

With multiple hook block options of 50, 15, and 6 tonnes, the QUY50A can handle a variety of lifting tasks. The crane’s overall weight is 50 tonnes (with the basic boom and 50t hook block), making it manageable for transport between sites. The A-frame is extendable and retractable, facilitating efficient setup and breakdown, while the machine’s dimensions allow for easy transport and storage.

The Fuwa QUY50A’s design prioritizes versatility, safety, and operator comfort, making it a practical choice for contractors who need a reliable, mid-capacity crawler crane for a range of lifting operations.
