GQ series crane application range
 
GQ type fixed load luffing crane, using single-arm rack, steel wire rope luffing and four-point contact ball slewing bearing structure, and set the pulley compensator, can make the approximate horizontal movement of goods, to achieve full amplitude transformer, the load amplitude faster, high work efficiency, can be 360 ° all rotary.This machine has the advantages of novel structure, stable transmission, high efficiency, easy operation, low failure rate.According to user needs, can adopt frequency conversion control, the use of institutions is more stable and reliable operation


The pier fixed crane crane, double SuoPing grab, or more than double cable disc grab grab (lotus), can work full load amplitude loading and unloading.Suitable for frequent continuous operation, the place that a lot of work, such as ports and inland port, the library field, logistics, freight yard, concrete mixing station, power plants and other places of bulk, such as yellow sand gravel, cement, coal, ore, mineral powder, slag, quartz sand, limestone, salt, food, gypsum, garbage, etc.) of the handling operation.
Workability luffing crane stationary arm
 
1. The main technical parameters, please contact to the company's web site www.lsdcm.com, more scheme figure at http://www.lsdcm.com/case
2. The structural characteristics of
1) the jib
Using triangle frame structure, mainly by the channel steel welded together, novel structure, easy manufacture, low quality and easy maintenance.
2) shaft bracket, turntable, base
By the channel steel welding adult glyph structure.Wheel adopt i-steel structure.The pedestal cylinder structure.
3. The main drive system, structure and layout
Hoisting, derricking and slewing driven by motor respectively, each independent system, can separate action, joint action.

Transmission chain hoist:
Motor and hydraulic push rod brake to zq type reducer, drum.The winding wire rope up or down to the goods.
Luffing mechanism transmission chain:
Motor and hydraulic push rod brake to zq type reducer, drum.Winding wire rope hoist boom pitch.
The luffing mechanism adopts double brake.Secondary hysteresis brake the brake smoothly, reduce boom vibration, safe and reliable.
Slewing mechanism transmission chain:
Motor and vertical planetary reducer (within the limit torque coupling, a hydraulic outside foot brake) - > 360 ° rotating pinion and big gear cooperation.
Or the motor - hydraulic brake pedal - worm reducer in a cone (limit moment coupling) - > 360 ° rotating pinion and big gear cooperation.
Crane upper support on the single row four-point contact ball bearing or on a single cross roller bearing, make it smooth and reliable operation.
 
 
 
4. The operation and control
The use of three phase four wire 380 v, 220 v ac power supply.Alternating current (ac), introduced from the terminal power supply box, through the crane sihuan center within collector into the hoisting, derricking and slewing control cabinet.Main controller control ascending, descending, growth, damping, forward, inversion, each have five files.Institutions can work alone can also be joint operation, easy to use, high work efficiency.
5. The characteristics and using range
1) the characteristics of
(1) using single arm frame pulley block compensation system, ensure the goods according to the approximate horizontal movement in luffing process, improves the accuracy of operation, to avoid the displacement of the goods and the consumed power, decreasing amplitude power, improve production efficiency.
(2) using single row four-point contact ball bearing or single cross roller bearing, on the upper part of the vertical force and overturning moment and horizontal force, make the crane can freely and 360 ° rotation.
(3) there are clear, good performance, low cost.
) the applicable scope
3) small and medium-sized ports can be used for loading and unloading of 100 t ~ 2000 t ship, can also be used by yard warehouse loading and unloading groceries or bulk.
