MGK Model 5t-1200t Boat Handling Crane,Lifting Equipment,Crane

Product Description:

Profile

The MGK Model 5t-1200t Boat Handling Crane is designed according to the user's requirements and it used to transport various hulls. In the design, it is fully considered that the hoisted object may exceed the height of the top cross beam, so the "U" shape structure is selected so as to be lifted into the boat handling crane.

This kind of crane can store ships on shore to make it easy to maintain and repair these facilities and reduce the cost of ship maintenance. The MGK Model 5t-1200t Boat Handling Crane is mainly composed of main structure, control system and the following organizations.

Overall Drawing

Main Structure

The main structure is composed of lower stringer, outrigger, upper stringer and top rail; the lower end of the supporting leg is connected with the lower stringer, and the upper end is connected with the stringer; the upper stringer is connected with the two ends of the top rail respectively to composed of a C-shaped structure.

 Dynamical System

The dynamical system provides electrical energy for diesel generating sets, and is used for the power consumption of hydraulic systems, control systems and lighting.

The main components are:

1. Diesel engine         

 2. Battery pack

3. Connecting piece       

4. Main pump  (Motor / pump)

5. Auxiliary pump        

6. Distributor

7. Hydraulic oil container  

8. Return oil filter

9 .Air filter             

10. Fuel tank

4. Hoisting Mechanism

The hoisting mechanism is composed of hydraulic winch, guide wheel group, fixed pulley block, movable pulley block and sling. The winch is installed on the lower stringer, and the guide wheel set and the fixed pulley block are installed on the upper stringer. The wire rope is connected between the winch, the guide wheel set, the fixed pulley block and the movable pulley block; the corresponding movable pulley block is equipped with a sling for lifting the boat.

The components of hydraulic winch are:

                          1.Brakes 

                          2.Hydraulic motor  

                          3.Reducer  

                          4.Reel     

                          5.Frame

5. Travelling Trolley

Travelling trolley is diagonal structure, the diagonal trolley is placed on the top of the main beam and the side of the sliding track. Chain wheel is arranged at both ends of the top rail of the main beam, and it installed on the main beam what is fixed on both sides of the diagonal trolley. Drive the chain wheel of one end of the main rail to slide through the slider on the main sliding track to make the trolley move horizontal, so as to adjust the the lifting point spacing of the hoisting mechanism.

15. Handling rod of lifting 

16 Handling rod of trolley movement 

17. Handling rod of long distance movement 

18. Handling rod of crane horizontal movement 

Considering the requirement of customer, the developed MGK model 5-120t boat handling crane by our company has following advantages

The MGK model 5-120t boat handling crane is made up of main structure, running wheel sets, lifting mechanism, steering mechanism, hydraulic transmission mechanism, electrical control system and other systems.  The main structure is  type, which can transfer the boat that height is higher than the boat handling crane. The rubber-tyred travelling system has the function of diagnal, 90°steering or steering on site. In line with the requirement, the body of the ship can be placed on the any specified places. It can quickly and flexibly arrange the body of the ship in tow. It can quite shorten the distance among the body of ship, which can save the storage space.  

The lifting mechanism, traveling mechanism and horizontal movement adopts electric-hydraulic , transmission system, which has the advantage of stable traveling of transmission device, show quick reflex, small inertia, high-speed starting, braking and steering, small volume, light weight,compact structure, simple and convenient operation, tending automation. It can realize step speed regulation during operation conveniently, which has overload protection.

The lifting mechanism adopts multiple-point lifting. All the lifting points can realize linkage. Also, it can realize separate adjusting, which can dispersion force on the body of the ship, which can realize balanced lifting. The distance among each point can be moved to adjust for satisfying the requirement of different body of ship.

It adopts soft and strong lifting belts to lift the surface of shipper, houseboat or wooden boat uniformly. And it will not damage the surface of the boat at all.

FAQ

Whether if the lifting capacity and boundary dimension of the products can be ordered in according with the requirement of user?

Certainly.

What’s the manufacturer of the hydraulic and electronic component?

Often, it adopts international mega brand, such as Danvers, Rexroth, Brevini, ABB, Siemens and others. Also, it can use the assigned brand by user.
