The QUY80U crawler crane is developed with the North American market in mind on the basis of our company's many years of crawler crane manufacturing experience. The product has passed the North American certification. It provides superior lifting performance and optimum safety. And it features loaded travel, 360°full swing operations, and retractable crawlers. The boom length is 42'8''-190'3'' and the fixed jib length is 29'6''-59.
Optimum lifting performance
1) Max. Lifting Torque=360USt.m;
2) The boom lifting performance is well above that of crawler cranes of the same grade engine (265bhp), which complies with the most stringent emission standard in the world.
1) Stringent emission standard
QUY80U is equipment with the Cummins QSL9-Tier 4F engine (265bhp),which complies with the most stringent emission standard in the world.
2) Low Noise Level
The product, as measured in accordance with appendix G of EN3000 and 2000/14/EC, registers a sound pressure level of 74.2dB(A) and a sound power level of 105dB(A)in the cab, with a measurement error if 3dB(A).
1) The primary and secondary hoist winches are designed with the gravity hook-lowering feature.
2) The boom –end single pulley mechanism allows fast lifting of light loads.
Highly Reliable Components
1) It transport weight with crawler beams is not more than 90,000lb(40.5mt); and
2) Its heaviest assembly is 9,700lb(4.4mt), making installation and transport extremely easy.
Complete safety protection measures
Its safety protection measures include torque limiting, hoisting monitoring, hook height limiting, boom rearward protection, and emergency stop button.
1) The centralized lubrication system measuring devices newly added to the hydraulic system are located near crawler beams, where the pressures related to all operational functions are collectively measured.
It features small transport weight and lightweight assemblies.
2) Its transport weight with crawler beams is not more than 90,000lb(40.5mt); and
3) Its heaviest assembly is 9,700lb (4.4mt),making installation and transport extremely easy.
