QUY50 Crawler Crane Main features Outstanding lifting capacity: leading the trade and exceeding your imagination! 1. The control system applied to this type of crane is an electronic management system, which adopts CAN bus technology, has intelligent fault diagnosis function and is equipped with intelligent color display. 2. The pendant plate made of high-strength plate, which has taken the place of traditional wire rope, has the advantages of excellent rigidity, light weight, great load-bearing capacity and low wind drag etc. 3. The crane is equipped with a self-assembly/dismantling system. No auxiliary crane is required for loading, unloading, assembly and dismantling. 4. The actuating time of brakes and the opening time of valves fitted in winch mechanisms can be adjusted freely to optimum matching state. The applied advanced PLC controller can make every speed parameter be adjusted within specified range in accordance with the user's habit, which embodies the ergonomic design of our crane. 5. The slewing mechanism has controllable free swing function which can reduce the impacts on the crane and ensure that superstructure starts/stops slewing more stably. The external slewing ring and slewing reducer with great load-bearing capacity and high precision can ensure stable and precise slewing motion. 6. The traveling mechanism can make the crane have high maneuverability and perform such motions as traveling in straight line, one-side crawler steering, differential steering and turning on the spot as well as traveling with load. 7. The crane has free-fall function. 8. The main pump control system, which has the functions of advanced load feedback and electrically-controlled power adjustment, makes the crane have good jogging performance so as to satisfy the demands in different working conditions required by customers. |

1.Boom system |
|
The boom is lattice structure and of high-strenght tubular product. Main boom Main boom length:13m ¡« 52m Adjusting lengthened boom section length for main boom:3m,6m or 9m Fixed fly jib Fixed fly jib length:6 ¡« 15m Adjusting lengthened boom section length for fixed fly jib:3m Main boom + longest length of fixed fly jib:43m + 15m |
2.Mechanisms |
|
Main hoist mechanism |
| It consists of concealed axial piston hydraulic motor,balanced valve,reducer,normally closed brake,clutch and wire rope.It is independent of other mechanisma to be operated. The main hoist mechanism possesses free-fall function.(Optional) The main hoist mechanism is two-speed type,having two kinds of lifting speeds,which can improve working efficiency. |
Auxiliary hoist mechanism |
| It consists of concealed axial piston hydraulic motor,balanced valve,reducer,normally closed brake and wire rope.It is independent of other mechanisms to be operated. The auxiliary hoist mechanism is two-speed type,having two kinds of lifting speeds,which can improve working efficiency. |
Boom hoist mechanism |
| It consists of concealed axial piston hydraulic motor,balanced valve,reducer,normally closed brake,pulley block and wire rope.It is independent of other mechanisms to be operated. It has ratchet self-locking protecting mechanism,which can prevent luffing gear from slipping because of long time parking. |
Slewing gear |
| It consists of concealed axial piston hydraulic motor,gear reducer,brake,pinion gear and slewing ring.The superstructure can realize 360¡ãslewing via slewing ring which is driven by pinion gear. Since slewing gear adopts closed hydraulic system with controllable sliding control,it is steady to start or brake slewing without impact.With internal gear slewing ring and slewing reducer,slewing gear possesses the advantages of great load capacity and high accuracy to ensure the stability and accuracy of slewing.Slewing can realize stepless speed regulation varying from 0 to 3r/min. The slewing gear can be locked by two mechanical locking devices in front of the slewing table. |
Traveling mechanism |
| It adopts double-motor and double-reducer.Two sets of control levers respectively control two tracks'traveling to realize straight-line traveling,one-sided steering,differential steering,spot turn and traveling with load etc.,which ensure the crawler crane has great mobility and flexibility. Traveling speed:0 ¡« 1.6km/h Gradeability:40%. Tension degree of track can be adjusted by jack.It is very quick,convenient and reliable. |
Mast mechanism |
| It consists of mast,pendant plate of mast,self-assembly/dismantling pendant plate etc.It is used for self-assembly/dismantling of the crane.Before doing this work,the mast should be turned back to connect the pendant plate,disassemble and assemble the counterweight. The mast must laid flat on the rear side of slewing table during traveline. |
Counterweight and counterweight assembly/diamantling mechanism |
| It consists of two pieces of counterweight, mounting pin fo counterweight,fixing chain etc.QUY 50 crawler crane can realize self-assembly/dismantling of counterweigh. |

Centralized display system |
| Large LCD possesses the function of Multilanguage display and can display operating signals collected by PLC controller, such as revolutions of engine, water temperature, fuel pressure, hydraulic pump pressure, pressure of main motors and operating level of basic machine etc. It can monitor working state in real time and give out a yellow or red warning signal when the working state of crane is abnormal. |
4.Safety equipment |
| Load moment limiter |
| It consists of load moment display and digital LCD. When
actual load moment reaches 90% of rated load moment, the warning lamp lights up and the buzzer alarms; when it reaches
rated load moment, the crane stops working automatically to
prevent accidents from occurring due to overload during
operation and ensure normal and safe work. It displays following data: Moment ratio Elevation angle of main boom Main boom length Working radius Actual load Permissible lifting load Max. permissible lifting height |
Hydraulic system |
| The overflow valves in the hydraulic system can restrain abnormal high pressure in loop to prevent hydraulic oil pump and hydraulic motor from being damaged and prevent hydraulic system from overloading. |
| Hoisting limiter |
| Prevent hook from lifting excessively and avoid accidents occurring. |
Boom angle indicator |
| It is mounted at the lower rear side of foot section (namely the right side of operator s cab). The driver can observe the elevation angle of boom clearly from the cab. |
Motion limiter |
| The system can ensure that the angle of actuating arm is within the specified range. |
Level sensor of the complete vehicle |
| Detect the level state of the complete vehicle. |
Anti-unhook device |
| Prevent load from falling off from the hook when lifting. |
Ratchet locking mechanism of luffing gear |
| Prevent luffing gear from sliding down because of long time parking. |
