7 5. Mechanisms Traveling mechanism. Systems 7. Safety Devices Primary and secondary lifting mechanisms The primary and secondary lifting mechanisms are both comprised of an internal variable displacement axial plunger hydraulic motor, balance valve, speed reducer, normally closed brake, and wire ropes; they can be controlled independently of other mechanisms. The wire ropes used are imported from Germany; they are of the highest quality and are anti-rotating. The primary and secondary lifting mechanisms allow for stepless speed regulation from zero all the way up to the maximum speed, thus dramatically enhancing operational efficiency. Primary and secondary lifting mechanisms Drum diameter Luffing mechanism mm m/min Φmm m/3m The luffing mechanism is comprised of an internal fixed-displacement axial plunger hydraulic motor, balance valve, speed reducer, normally closed brake, and wire ropes; it can be controlled independently of other mechanisms. The wire ropes used are imported from Germany and they are not antirotation. Luffing mechanism Operating speed of the outermost layer Diameter of primary and secondary lifting mechanisms' wire ropes primary and secondary lifting mechanisms' wire ropes Rated single rope tension 5t Drum diameter mm Operating speed of the outermost layer Diameter of primary and secondary lifting mechanisms' wire ropes primary and secondary lifting mechanisms' wire ropes Rated single rope tension m/min Φmm m 5t The traveling mechanism is a dual-variable motor dual-reducer type; the hydraulic motor, traveling speed reducer and traveling brake valve are all imported products. The two crawlers are controlled by two different control handles, allowing for a variety of traveling actions such as straight line traveling, unilateral steering, differential steering, pivotal steering, driving with load, etc., thus offering a high level of mobility, maneuverability and flexibility. Traveling speed: ~.km/h. Gradeability: %. Crawler tensioning: crawlers are tensioned through jacks, making adjustment is fast, easy and reliable. Mast jack-up mechanism This mechanism is comprised of the mast, mast jack-up oil cylinder, auxiliary hydraulic system, etc.; this mechanism is used during selfassembling/disassembling (or relocating) of the whole machine. Plate connection is employed between the oil cylinder and balance valve to provide higher safety and reliability. The anchoring rods can be connected, the boom can be assembled, and the crawler assembly and counterweight can be mounted by jacking the mast up beyond perpendicular from its horizontal position. Control room swiveling and luffing mechanism The control room can rotate by from the side of the rotating platform to the front of the rotating platform and be fixed there using locating pins, thus reducing the width of the overall crane and making it easier to transport. The control room's luffing is controlled through oil cylinders; when lifting to especially high heights, the control room can luff upwards by, thereby dramatically expanding the driver's field of vision. Counterweight and counterweight loading/ unloading mechanism This mechanism is comprised of the counterweight base plate, counterweight, counterweight jack-up oil cylinder, load bearing chain, and fixing pin oil cylinder. Hydraulic system The hydraulic system is comprised of a main pump, control valve, hydraulic motor, hydraulic oil tank, and cooler, etc. The hydraulic system employs one of the world's most advanced pump control systems and load sensitive systems; imported products are used for all major components to save energy, and ensure high efficiency, high reliability, and long service life. Capacity of hydraulic oil tank: L. Cooler: aluminium radiator, where the fan is powered by the electric motor. Electrical system DC V, negative ground, x 5AH batteries. The electrical components of the vehicle primarily include: power supply, engine starter, engine misfiring, indicator lights, alarms, lighting devices, fans, windshield wipers, horn, lifting height limiters, hydraulic oil cooling fans, digital display monitor, PLC controller, engine preheater, safety devices, etc.; these appliances ensure that the crane will operate safely and provide a comfortable working environment for the driver and other workers. The whole vehicle employs CAN bus technology, which connects the engine, PLC controller and digital display together with fault detection and self-diagnosis functions. Power system Engine: US Cummins QSL-C5 Rated output power (kw /rpm): 7/ Maximum output torque (Nm/rpm): 5/ Emissions standard: U.S. EPA Tier 3 and EU Stage III For the fuel tank, a large-volume L tank is used to ensure a sufficiently long working time of the engine. Load moment limiter The limiter is comprised of a digital LCD monitor, host computer, signal converter, sensors, etc. When the lifting load reaches % of the rated load moment, an alarm lamp will light up and a buzzer alarm will sound; operation of the crane will stop automatically when the lifting load moment approaches the rated load moment in order to prevent any incidents that may occur as a result of crane overloading during construction operations, thus helping to ensure normal and safe operation of the crane. The digital LCD monitor can display the following data: Moment ratio Main boom elevation angle Working radius Actual hook load Allowed lifting load Maximum allowed lifting height Various overflow valves in the hydraulic system These valves can suppress abnormally high pressures in the circuit, preventing damage to the hydraulic oil pump and motor, and preventing system overload. Height limiter devices The limit switch, movement weight and other components are mounted on the top section boom, and are used to prevent excessive lifting of the hook. When the hook is lifted to a certain height, the limit switch signals the electrical system to automatically stop the lifting of the hook, also setting off an acoustooptic warning through the buzzer and display screen in the control room to prevent overwinding of the hook. Angle indicator The boom angle indicator is located along the lower rear part of the boom's bottom section (right side of control room), allowing the driver convenient, clear visibility of the elevation angle of the boom from the control room. Slewing mechanism It allows for complete self-mounting and dismounting of the counterweight, thereby dramatically improving the crane's utility and reducing the risks involved in manual installation. Digitalized display system Working boom limiting position alarm and protection system The slewing mechanism is comprised of an internal dual-variable displacement axial plunger hydraulic motor, double gear speed reducers, normally closed slewing brake, pinions and slewing bearings; the piniondriven slewing bearing allows for full 3 slewing movements, thereby providing slewing functionality to the upper machinery. The slewing mechanism is equipped with a controllable slip-turn function to reduce shock and allow for higher stability during initiation and braking. The slewing mechanism adopts a closed-type slewing system to reduce shock and allow for better stability during initiation and braking of slewing operations; the controllable free slip-turn function of the slewing mechanism more fully meets operational requirements. The slewing mechanism offers stepless speed regulation within the range of ~.r/min. During transport, the slewing mechanism is lockable through two mechanical locking devices located at the front of the rotating platform, thereby ensuring safe transportation. Outrigger lifting and crawler self-mounting and dismounting mechanism The outrigger jack-up and crawler self-mounting and dismounting mechanism is comprised of the undercarriage outriggers, outrigger oil cylinders, undercarriage operating valves, and crawler power pin, etc. The outrigger jack-up mechanism serves as the primary load carrying mechanism during the crawler self-mounting and dismounting process, while the crawler self-mounting and dismounting mechanism lifts and installs the crawler assembly through the mast and mast jack-up mechanism, and uses the power pin to connect the chassis frame and the crawler assembly together. When no auxiliary lifting equipment is available, the outrigger jack-up and crawler self mounting and dismounting mechanism can independently mount and dismount the crawler assembly, thereby improving operational efficiency, reducing the manual work intensity, and avoiding the risks involved in manual control. The.4-in LCD monitor, with multi-language display capabilities, can centrally display the various operating mode signals collected by the PLC controller, including engine's rotating speed, water temperature, engine oil pressure, hydraulic pump pressure, motor pressure, level of the main machine operations, etc. It can monitor working conditions in realtime; when the crane is working abnormally, the system will emit a yellow or red alarm. Centralized lubrication system The German-imported Beka centralized lubrication system is incorporated to significantly prolong the service life of the whole vehicle. This protection system has a load moment limiter and limit switch for dual-level control, enabling automatic termination of luffing movements of the boom's limited elevation angle position, while also simultaneously triggering an acoustooptic warning. Boom overturn protection device The brace poles, which are of a nested steel tube and spring structure, are mounted at the base section of the. They employ springloaded compression force to provide support and to prevent the main boom from overturning. Whole machine level sensor This electronic level meter displays in realtime the inclination angle of the whole machine and sends an alarm to the digital display screen in order to ensure safe operation of the vehicle.

8 Hook safety latch This device prevents the load from unhooking when lifting heavy loads. Wire rope overwinding and over-release protection device When the wire rope in the drum has been released until only three single wound coils remain, this protection device signals the electrical system to automatically cut off the releasing of rope and the descending hook, also setting off an acoustooptic warning through the buzzer and display screen in the control room.. Control Room The structure of the control room is made entirely of steel, is surrounded by reinforced glass on all four sides, and has laminated glass for its sunroof and windshield. The interior is equipped with a sun shield on the right side, adjustable seat, windshield wipers, electronic control handle, load moment indicator, digitalized display monitor, various switches, auxiliary remote control box operating assembly, air conditioners, electric fans, illuminating lamps, CD player (DVD player optional), cigarette lighters, and fire extinguishers, etc. The control room offers a broad field of vision, and a spacious and comfortable interior.
