Profile

As a kind of crane, the portal crane is widely used in harbor, wharf, station, stockyard and other open yard. At these places, the ships and vehicle need a kind of high-efficiency equipment to handle and transfer the materials, which aims to quicken the turnover of the ships and vehicle. Portal crane has following good performance, such as, advanced performance, high-efficiency  operation, compact structure, balance working system, comfortable operation, reliability and stability, convenient maintaining, good appearance and other advantages. Also, it can make full use of the harbor, wharf and limit site. It can meet the requirement of the access of the vehicle  and the ship with the empty load and full load. Especially, it is suitable for common wharf, which can complete the handling the containers, sundries and bulk material along the front of the wharf. It is a kind of low investment and effective lifting equipment.

On the gate type engine base, it loads rotating part of the portal crane. In fact, the gate type engine base is the main bearing part. Under the gate type engine base, it is equipped with the traveling mechanism, which can run on the rail which is set on the ground. On the rotating part, it is equipped with four mechanisms, such as cantilever and lifting mechanism, rotating mechanism, jib lubbing mechanism. These four mechanisms can realize cooperative work. Then, by means of these four parts, it can realize the installation of the body of the ship and equipment,or it can handle the material.

The structure of the portal crane

The portal crane is mainly divided into two parts, the upper rotating part and the bottom traveling parts.

The upper rotating part include following parts, such as, jib system, propeller strut, rotating platform, cab, machine room and etc. In the machine room, it is installed with lifting mechanism, jib lubbing mechanism and rotating mechanism. The bottom traveling part includes gate seat and traveling mechanism.

The four main parts of the portal crane

Lifting mechanism

As a kind of lifting mechanism, it is used to move the material upward and downward. Generally speaking, by means of changing the spinning direction, it can control the crane lifting the material upward and downward. The lifting mechanism is made up of drive mechanism, coiling system of steel wire rope and fetching mechanism.(The fetching device of the portal crane, commonly, contains hook and grab.)

Jib lubbing system

Making use of the jib lubbing mechanism, the portal crane can change the handling route of the material to complete the loading and unloading the material. Under loading, the amplitude of variation of the jib is called as operation luffing mechanism. Without loading, the amplitude of variation is called as non-operation luffing mechanism. In order to enhance the productivity, the portal crane is widely used operation luffing mechanism.

Rotating mechanism

The rotating mechanism of the portal crane is used to move the lifted material horizontally along the circular arc. Combining with the lifting mechanism and luffing mechanism, it can move the lifted material to the any positions in the luffing range. The rotating mechanism is mainly made up of two part, such as, the rotating and supporting device and the drive part for making the rotating part spinning.

Traveling mechanism

The traveling mechanism is mainly up of three parts which includes traveling supporting device, traveling drive mechanism and safety mechanism. The supporting device includes beam, wheel and lock shaft. The drive device includes electric motor, brake and reducer. The safety mechanism traveling mechanism includes rail clamping device, buffering, normal limit switch, sweeping rail plate and etc.
