Characteristics of light tire-type container gantry cranes for ports

The light tire-type made in china ship building gantry crane equipment for ports can meet the loading and unloading needs of existing cargo types, and has functions such as customs declaration, inspection, foreign trade, and storage. Moreover, its operation efficiency is high and it can take into account the company’s subsequent container development. Light tire-type container gantry crane has the following characteristics:

The lightweight tire-type container gantry automated ship building gantry crane system can meet the actual needs of different owners. It uses diesel generators and mains electricity as power sources. It can be equipped with diesel generators or power distribution boxes at the yard. The weight of the whole machine is only 70% of the conventional one, because the equipment is designed to be lightweight.

Compared with conventional equipment, the price is 65% lower, and the wheel pressure and dead weight of the whole machine are reduced. Compared with conventional equipment, the basic investment of the equipment can be saved by 1/3. In order to reduce the power of the lifting motor, constant power vector is used for lifting. The lifting mechanism is controlled in a closed loop, while the large and small car operating mechanisms adopt V/F control. In order to realize the deviation correction of the truck, manual method is chosen. Two frequency converters are used to control the two drive motors in the trolley’s operating mechanism, using V/F control. According to the running track of the equipment, the rotation speed of the drive motors on both sides needs to be changed. The driver can use the correction handle on the console to make the wheels on both sides travel at different speeds and correct the operating error of the entire machine cart.

The communication method of Profibus can provide the interface to equipment manufacturers for function expansion without changing the existing hardware. By optimizing the original software configuration and programming, the purpose of increasing functions can be achieved. In order to meet the loading and unloading needs of different types of cargo, optional container spreaders or lifting beam hooks are available. Lifting beam hooks can be used for loading and unloading operations such as spiral steel, rebar and hot-rolled coils. When loading and unloading containers, special container spreaders are used.

In terms of application, it can not only be used for the manufacture of ships. After the trailers transport the containers unloaded from the ship by the quay wall container carrying bridge to the yard or rear, they are stacked by the shipyard crane or directly loaded and transported away, which can speed up the container transportation. Carry bridge or other industrial ship building gantry crane for sale turnaround. A yard that can stack containers with 3 to 4 layers in height and 6 rows in width is usually of tire type, but rail type is also used.

Compared with container straddle trucks, container gantry cranes have larger spans and heights on both sides of the gantry. In order to meet the transportation needs of port terminals, this kind of crane has a higher working level. The lifting speed is 8 to 10 meters/min; the span is determined by the number of rows of containers that need to be spanned. The maximum is about 60 meters, which corresponds to the lifting weight of 20-foot, 30-foot, and 40-foot long containers of about 20 tons and 25 tons respectively. and 30 tons. Container crane manufacturers have struggled and developed in the wave of market economy, and currently have high credibility and good reputation in engineering and construction sevencrane ship building gantry crane. It marks that our service and management level have reached a new height. We are willing to develop together with people of insight from all walks of life to create a better future.
