Twenty years of fierce market competition and persistent improvement

have made Zoomlion the industry leader it is today.

In 2011, we will strike forth again with comprehensive optimization and upgrade for our

QY25VF series.

Aiming to further improve and empower our 25t cranes - the mainstream mid- and

light-duty vehicle model - the QY25VF series will now feature a much more attractive

overall appearance and provide world-leading performance parameters in lifting height,

main boom length, working speed, and lifting capacity, etc.

Boom: it offers powerful lifting performance, is suited to a wide range of operating modes, and features smooth boom retraction movements.Slewing: slewing movements feature excellent smoothness and inching performance, making the crane ideal for use in various hoisting operations that require precise positioning.

Boom/SlewingZoomlionFully Hydraulic Truck CraneQY25VF

Cruciform cross section and adoption of Class HG80 high-strength steel material;Large outrigger span, excellent overall structural rigidity, and optimized overall mass distribution;In order to fully realize the boom's potential, the boom structure has been optimized using the ANSYS finite element analysis technique;Industry-leading boom manufacturing techniques. In the building of our cranes, we use imported 3000T boom bending machines from Sweden, industry-leading head-end butt joint dies and boom straightening machines, advanced specialized boom double-side boring machines and three-coordinate plotting measures;We offer a wide range of operating modes to choose from. Our vehicles' outriggers can be used in a semi-extended operating mode that allows the boom to retract freely, i.e. the third, fourth and fifth sections can extend before the second section;We also offer an embedded slider design and have adopted automatic sliding compensation technology.

We have adopted controllable slip-turn technology, similar to the Anti-lock Brake System (ABS), for our slewing brake;A large-diameter external geared slewing bearing is used to increase carrying capacity and to enhance the smoothness and maintainability of slewing;A high-performance 28 clino-axis slewing motor is employed, featuring small size and high volumetric efficiency. When working together with the new slewing speed reducer, it increases slewing smoothness and the service life of the transmission system; With an optimized system, the minimum stable slewing speed can reach 30min 12sec/revolution;The lateral rigidity of the rotating platform has been optimized, and the rotating platform's center of gravity has been lowered.

Luffing: high efficiency and stable movements.

Lifting: high efficiency, long service life, and stable movements.

Luffing/Lifting

Luffing movements are fast, with only 40 seconds needed to elevate the boom;

A large-diameter luffing oil cylinder is used, the diameter of which is 240mm;

A lowered power design has been used for the luffing hydraulic system.

The single rope speed of the main winch is 120m/min, and the single rope speed of the auxiliary winch is 100m/min;

Top-quality 4V wire ropes have been incorporated that are twisting and wear resistant;

A concealed dual-range winch has been adopted to deliver more effective rope guidance;

Both the main and auxiliary winches use variable displacement motors to guarantee high operating efficiency

and improved versatility of parts and components;

The hydraulic system and flowrate matching of valve parts have been comprehensively optimized.
