GHE4033 portal crane is mobile four links,rack luffing type. It does apply to

operate on jetty or port, rotational support is using slewing bearing, through slewing

driven mechanism to make the crane with 360°fully rotation and move on the rail which

is provided by the port.

This crane has hoisting,luffing and rotation mechanism. main metal structure includes

truss boom,slewing column,rotation platform and pedestal column and framework.

For safety equipment,This crane has load moment limiter,anemometer,aviation

obstacle lights,Lightning arresters and each part has relevant control limitation

protection.380V,50Hz.Crane’s power supply:AC380V,50Hz 3 Phase

general requirement

Crane’s mechanism should meet strength,stiffness and stability

requiremnt.the apperance of the mechanism is easy to maintain,repair,derust

and coating.there are leakage hole to get rid of water in each area.there are

checking passage for each area need check and repair.considering about the

effect of corrosive working environment.main bearing structure is welding structure.

unwelding parts will be applied hinged bolts and strong nuts to conncet

6.2 A frame and boom

A frame and boom are main force components,has enough strength and stiffness.the

windward area is small and wrest resistantance is betterand have a strong bearing

6.3 operating platform,walking board,ladder,handrail

operating platform,walking board,ladder should set at convenient and safe area for

repairing and checking or replacement parts.perating platform,walking board,ladder

are welded by steel,width of passage and ladder is less than 500mm,step distance is

in 180-230mm,walking board and operating platform’s plank use anti-slip steel structure,

ladder useHot dip zinc grille pedal,boom has checking ladder,operating platform,

walking board,ladder setting height is more than 1050mm with double handrail.

column distance is less than 2m,platform ,walking board and passage net height is

less 2m,vertical ladder’s width is less than 400mm,if the height is over 2m,has

protection circle.at the bottom of walking board,platform and passage has guard board

which is more than 60mm

7,Mechanism

7.1 Lifting mechanism

7.1.1 Lifting mechanism is consist of Electric motor, reducer,brake ,and wire rope reel.

7.1.2The brake of the lifting mechanism is normally closed electro-hydraulic block brake,which has good heat dissipation and stable friction coefficient.It ensure the machine can stop at any height accurately and safely in the working range in long-term heavy duty.

7.1.3 At the end of wire rope drum,there is a crane height limiter,which has maximum/Minimum lifting heigth limit fuction.

7.2 luffing mechanism

7.2.1 The luffing mechanism is consist of electric motor,reducer,brake,gear and rack.

7.2.2 The luffing mechanism adopts gear and rack drive,together with boom balancing system.

7.2.3 The luffing mechanism has maximum and minimum amplitude limit device. Decelerate before amplitude reach maximum and minimum.and there is a light indication anf sound alam. When reach the limit position ,the amplitude will stop. Then the luffing mechanism can only working in the opposite direction.

7.3 Rotating mechanism

7.3.1 Rotating mechanism is consist of rotating drive and slewing bearing. Rotating mechanism adopts motor reducer drive,which has features of stable, safety,reliable and achieve 360 degrees all rotary.

7.3.2 Rotating drive device is consists of motor ,limit moment coupling,hard tooth vertical planetary gear reducer,mechanical hydraulic brake,handle brake,output shaft pinion.and rotating bearing device. The limit moment coupling can protect the motor and transmission parts when overload.

7.3.3 The rotating bearing device adopts three row roller bearing device.Equipped with electric pump is convenient for lubricating and ensure it in good lubricate condition.

8.The main components

8.1 Wire rope

The structure and property of the wire rope is selected according to the national

standard,and in the line with crane design specification.what’s more ,it has the

factory certification.

8.2 drum

8.2.1 Made by steel plate bending welding drum,weld annealing and the NDT inspection.

8.2.2 The drum adopts single winding

8.2.3 There are should be at least 3 circle safety-rope ,when the hook at the lowest position.

8.3 pulley

8.3.1 Using hot-rolled pulley,which groove has been precise rolled and sintered.

8.3.2 The pulley is setting the prevent jump rope protection device.

8.3.3 To convenient the replacement and spare parts,when in design and choose the pulley,the seriation and standardization pulley has priority.
