The eight most common heavy machinery in modern port terminals (2)

At present, information technology has been applied to all aspects of port production, from internal production scheduling, terminal operations, business management, and security supervision of port enterprises to external EDI data exchange, logistics platforms, and port platform construction. In the next few years, the port machinery and equipment market will expand rapidly. Let's take a look at the most common machinery and equipment currently in port terminals.



Empty container stacker


Empty container stacker is the key equipment for container transportation. The stacker is widely used for stacking and transferring empty containers in ports, docks, railway and highway transfer stations and yards. It is a supporting product for shore bridges, field bridges, and front cranes. It has the advantages of fast moving speed, high operation efficiency, flexible maneuverability and space saving. In recent years, with the rapid development of the domestic logistics industry, the number of containers in each container yard and transfer station has increased significantly, the problem of small and tight sites has arisen, and site costs and site restrictions have been expanded. Therefore, all freight yards and transfer stations are considering using height. Each container stacker production plant meets user requirements by improving the mast device in its working mechanism. Now there are empty container stackers with a lifting height of 20m, 9 stacking yards, and a 13m mast height. 


The stacker is mainly composed of power transmission system, steering system, frame system, mast system, spreader system, cab and operating system, air conditioning system, electrical system and hydraulic system. When the stacker is working, the spreader lock pin locks the container, the lifting hydraulic cylinder expands and contracts and drives the chain to move the container up and down the mast; the expansion and contraction of the tilting hydraulic cylinder realizes the mast leans forward and backward; the diesel engine output power passes the walking transmission system Drive the whole vehicle to walk, so as to realize container handling and stacking operations.


At present, the market prospects of high-reliability and superior-performance products, as well as mechatronics forklifts and stackers equipped with advanced electronic technology are promising. Relying on the development of warehousing, develop new varieties, especially forward-moving forklifts and stacker trucks. The calculator technology has been gradually promoted and applied on electric forklifts, and it is equipped with information control. The unmanned forklift will be suitable for the needs of toxic or special environments, and has a large space for development.

With the acceleration of internationalization, product safety has become a threshold for Chinese companies to enter the international market. The square and pointed appearance of the forklift is being replaced by a streamlined arc shape, which improves the driver's field of vision and improves operational safety. 



Container spreader


Container spreader is a large-scale special equipment for container handling. It is suitable for freight storage, water transportation ports and docks. Because it is a special equipment, it has the characteristics of high reliability, stable operation and high operating efficiency. It is an important auxiliary tool for lifting equipment.


Container spreaders are usually used in conjunction with loading and unloading equipment such as shore container cranes, tire-type container portal cranes, rail-type container portal cranes, container straddle carriers, and portal cranes. It has a structure compatible with the container box, and is connected to the box corner pieces of the box through a turn lock for lifting operations. Container spreaders can be divided into unpowered spreaders and powered spreaders according to the presence or absence of power sources.


The container spreader adopts the structure design of semi-automatic or automatic elastic zipper control. The entire operation process of the spreader does not require the use of auxiliary components. It is a purely mechanical operation mechanism. Opening and closing makes the operation of the spreader convenient. Improved the efficiency of container handling operations.

Floating crane


A floating platform carrying a crane, which can be moved to any place in the port where it is needed, either moored or moved to an anchor to transfer cargo. Floating cranes can usually lift overweight cargo. Mainly used for loading and unloading of large cargo. There are lifting equipment on the ship, and the boom is fixed and rotary. The lifting capacity generally ranges from hundreds of tons to thousands of tons. Can also be used as a port engineering ship.


Cranes are generally divided into two categories, one is that the boom can rotate 360 degrees, and the other is that the boom is fixed in one direction on the ship. By pulling the anchor chain in different directions, the weight is rotated. The former has a very complicated structure and mechanical structure, and its lifting capacity is relatively small. Lifting vessels are also called floating cranes. It is used for water lifting and hoisting operations. It is generally non-self-propelled and also self-propelled. A crane is mounted on the ship. Frequently operated cranes are self-propelled, and their cranes can be rotated. When lifting very large pieces, two cranes can be used for operation.

Wheeled container gantry crane


Wheeled container gantry cranes (commonly referred to as field bridges) are specialized machinery for large-scale professional container yards, loading and unloading standard containers. It is not only suitable for container yards, but also for container yards.


The field bridge is powered by a diesel engine alternator. It adopts digital frequency conversion speed regulation and can move in two directions within the container yard. Equipped with a telescopic spreader capable of lifting 20-foot and 40-foot containers. Field and bridge spreaders often use fixed guides. In order to reduce the sway of the spreader, a mechanical stabilizer is installed. For the convenience of the box, it is equipped with a small angle slewing device for the spreader, in order to be able to change the field operation. Equipped with 00 ~ 900 right-angle steering mechanism. Under normal circumstances, the field bridge span has been standardized to 23.47 meters (six rows plus walkways), and non-standard span bridges can also be supplied. The lifting height can guarantee the lifting of a 40 'long 9'6 "container over four (or five to six) stacks of containers.


The field bridge is supported on large tubeless tires of 4, 8, or 16 wheels. The number of rounds is designed according to the requirements of the site wheel pressure. The cart walking mechanism can be four-wheel or two-wheel drive. In order to prevent the collision between the field bridges and between the field bridges and the containers, a manual correction system and a four-corner anti-collision device for the cart are provided.


The trolley running machinery can be driven by rack or dual-axis, single-axis, and runs smoothly. There is a cab under the small frame, and the driver operates the entire crane in the cab.


The field bridge adopts AC or DC speed regulation system, which has good speed regulation and constant power control, and can automatically adjust the lifting speed according to the weight of the box.
