On 16th Sep. 2020, one unit 50 ton truck crane QY50KA was loaded on vessel, it will be delivered to Mombase port Kenya.
QY50KA Truck Crane is a competitive product that tailor-made for customers by
Hoisting Crane Business Division, depending on technologies in K-series
cranes in more than 10 years and integrating several latest achievements in scientific
research
The whole crane has leading lifting performance and traveling performance, and
highest hoisting, elevating and telescoping efficiency in the industry. It is widely used in
various working sites such as construction sites, urban renewal, transportation, port, bridge,
oil field, mine field and other complex working environments.
(1) Leading lifting performance and traveling performance
With optimized structure design, boom length 11.4~43.5m, it has strong lifting
performance that is 5%~10% higher than products of same tonnage in the industry.
Large power engine contributes to excellent dynamic performance, strong grade
ability and good pass ability. Max. grade ability is 42%, max. travel speed is 80km/h.
(2) Mature and reliable double pump confluence technology, highest hoisting, elevating
and telescoping efficiency in the industry
The system achieves double pump confluence via telescoping, elevating and hoisting
operation so as to improve working efficiency and satisfy the demands of market and
customers;
Specially designed confluence multi-way valve, double pump confluence technology
is adopted in winch raising and lowering, boom telescoping and elevating up operation,
working efficiency in elevating and telescoping operation is leading in the industry.
(3) Improved reliability of radiation and electric systems, safer lifting and driving
operation
Double fold line winch is used in winch system, which greatly improves reliability.
Waterproof plug-ins with rubber bushinside is adopted in electric system, the crane
has good waterproofness and protection grade reaches IP65.
Air-conditioner condenser is arranged separately, system exhaust port is added to
future improve heat exchange rate of radiation system, permissible ambient temperature is
above 45℃.
Fuel tank made of aluminium alloy is adopted, which has good appearance and
quality, and strong corrosion resistance.
(4) Air-assisting shift gears bring more comfortable operation
Exclusive shift boost protection mechanism effectively avoids unsmooth shifting of
transmission. Compared with products of same tonnage in the industry, shifting force in
driving is reduced by 50%, shifting distance is decreased by 30%, comfort in operation of
customer is improved effectively.
(5) New upgraded outline and humanized design, more comfortable driving operation
With brand new operator’s cab, driver’s cab, engine hook and cover, the crane has
