Container straddle carrier is a special machine used for short-distance container handling between container terminal and container yard. It straddles the container with a portal frame, and is lifted by a hydraulic lifting system equipped with a container sling for handling and stacking. The container can also be loaded onto the container chassis by a straddle carrier, and the container can also be removed from the chassis. The container straddle carrier has the characteristics of high flexibility, high efficiency, good stability and low wheel pressure, so the container straddle carrier has been widely used in the container handling industry.
In recent years, due to the improvement of container straddle crane technology and the development of hydraulic and other related technologies, container straddle cranes show a diversified trend. In the host configuration, the single-host format still occupies a large market. This form of container straddle, the engine is arranged on the top of the container straddle carriers, control and maintenance is more convenient.
In general, two engines are arranged between the two sides of the door frame, and the safety and stability are significantly improved because of the low position of the engine. In terms of transmission methods, in addition to the traditional mechanical and hydraulic mechanical transmission methods, hydraulic transmission and electrical transmission methods have developed rapidly.
Lifting System
As the lifting structure of the container straddle crane, the winch trolley is equipped with a winch and pulley system, which can make the hoist or lifting device of the winch accurate vertical movement. The spreader uses a mechanical locking system that allows individual electronic monitoring of the locking or unlocking position. In addition, all locking systems have the same design to reduce the need for spare parts.
Steel Structure
The main girder structure of Huadelift’s container straddle carrier is made of high-quality steel, and the inner rail beams are strong and lightweight to reduce welding. The main beam structure achieves the best balance of flexibility and durability through the perfect design.
Dynamic System
Powertrain includes engine, transmission and other power-related systems. High performance, low carbon emission generator sets can save energy costs and protect the environment. At the same time, Huadelift also offers a variety of emission levels of engine units.
Cabin
The cabin is the control center of the container straddle carrier. The control room is equipped with large Windows to provide excellent all-round views. In addition to this, Huadelift has designed ergonomic adjustable seats to make the driver more comfortable during the work process.
Ladders and Mechanical Platforms
Ladders and mechanical platforms provide easy access for operators to get in and out of the cabin as well as to inspect engines, generators, hydraulics, etc.
In the selection of container straddle carrier, in addition to the lifting capacity should meet the needs of the total weight of the container and spreader, loading and unloading handling efficiency, stacking and through the layers of containers, body width, turning radius and stability and other technical performance parameters should also meet the requirements.
1. Lifting Capacity
Container straddle carrier lifting capacity is the maximum total weight of the lifted container and the weight of the spreader and. Usually the unit is expressed in “t”.
2. Stacking and Containers Height
Container straddle stacking and through the container layer (height) of the determination, and the entire container terminal storage area, storage capacity and specific operating conditions have a close relationship.
At present the use of cross-traffic car mode of container terminal yard, usually only two layers of stacking containers, which requires cross-traffic car lifting heavy box can be in two layers of containers through.
3. Loading and Unloading Handling Efficiency
For container specialized terminals, container straddle carrier loading and unloading handling efficiency should be adapted to the shore container cranes. Loading and unloading handling efficiency and cross-truck configuration of the number of units and loading and unloading handling work cycle time. Container straddle crane handling loading and unloading work cycle time is mainly composed of two parts: one is the handling operation time, the second is the loading and unloading stacking time. Container straddle carrier can only reach the highest speed when traveling in a straight line, and must limit the speed when turning.
In addition, the container straddle carrier due to the lifting height is small, in order to reduce the impact load when starting and braking, lifting speed should not be too large.
4. Width Size
Transporter is across the container rows and columns traveling. Its shape width and internal width dimensions will affect the overall layout of the container yard and the width of the lower part of the cross-traffic car. The smaller the spacing between the rows of containers, the container yard can be stacked on the number of containers is more. If the internal width of the straddle carrier is too small, it will affect the straddle carrier in the container or chassis car safe passage.
5. Minimum Turning Radius
Turning radius is an important technical indicator to measure the steering performance of the transporter. In use, the steering performance itself also reflects the maneuverability of the transporter.
The minimum turning radius of the outline of the transporter refers to the transporter handling containers, the steering wheel is at the maximum deflection angle, the outline of the farthest point from the center of the instantaneous turning radius of the arc trajectory. For example, the minimum outside turning radius of a straddle carrier handling a 40ft container is larger than that of a 20ft container.
As a professional container straddle lifting crane manufacturer, Huadelift has rich production experience and project experience. At the same time, as an experienced container straddle crane manufacturer, we can provide customers with the satisfied service.
Customized Services
