RT55U is a high-end model developed by and an experienced R&D
institute in Europe, which has been approved by CE in Europe. The
product is equipped with two-axle loading chassis and has two types
of driving model, four types of turning models and back-and-forward
driving function. The product has five sections of quadrangular
great circle main doom, H-type outrigger as well as combined
self-removal and installation counterweight. It has three types of
operation models such as operation with the support of outrigger,
operation with the support of tire and hanging when driving. It is
widely used in oil field, mine, road and bridge construction,
warehousing base and other construction sites.
Product Highlights:
1. Technology from Europe, Performance in Leading Level
2. The product is developed by China and Germany with delicate
design. The product has strong comprehensive lifting power with its
38.2m main doom and 17m auxiliary boom under the same boundary
conditions.
Maneuvering and Flexible, Quick and Efficient
3. The max speed reaches 25km/h (37km/h for option) and the max
gradeability is 55% and the min. turning radius is 5.7m. All these
three factors make it flexible.
4.The product is equipped with great power system, specialized
cross-country pattern tire and skid resisting differential locking
gear. All these three factors make it drive over all kinds of road
easily.
Safe and Reliable, No Worry to Handle
5. The product is equipped with lifting protection control system
in case of overload, over-retracting and over-stretching as well as
exclusive technology in this field like rear axle-wheel automatic
return-control system and safety-driving automatic protection
system. All these elevate its safety performance largely.
6. The product is equipped with top features in this field,
professional matching upgrading and systematic evaluation test. And
it has passed test like driving 4,000km and 10,000 times hanging.
Both ensure its reliability.
Economic and Environment Protection, with Cost Saving
7. The product is equipped with optical matching power transmission
system and torque converter with lockout function, which decrease
the oil consumption over 20% at high speed.
8. The flow distribution management technology makes the system
efficient; and the gravity drop luffing system needs no extra power
and save the oil consumption.
