Lifting of Container Tipping Trailer for Sale Zambia
Bracket Type Lifting
When it comes to packing of this type for container tipping trailer in Zambia, container is placed on the special bracket, the tractor and semi-trailer is put under the bracket, use the hydraulic lifting mechanism on the trailer to lift the box, then evacuate the bracket, put down the container, and the four corners of the contrainer are in place. Lock up and then drive away. The action is reversed when unpacking. The disadvantage of this method is that some special brackets need to be arranged at the loading and unloading place, the gap between the vehicle and the bracket is small, and it is difficult for the vehicle to enter and exit.
Outrigger Type Lifting
Four respectively independent lifting outriggers/landing gears are connected with the corner pieces of the container. Since the outriggers are lifted at the same time, the container is lifted, and then the container tipping trailer is driven under the box. The outriggers are lowered to place the container on the frame, four The outriggers are used to fix the box and the frame, and then the normal transportation can be carried out. The action is reversed when unpacking. There are three ways of outrigger lifting method: mechanical, hydraulic and electric. The disadvantage of this method is that it needs to be equipped with lifting outriggers or self-provided lifting outriggers of the transport vehicle group in the loading and unloading site. The gap between the vehicle and the outrigger is small and it is difficult for the vehicle to enter and exit in Zambia.
Loading of Container Tipping Trailer for Sale Zambia
For the rear loading and unloading method of container tipping trailer in Zambia, the self-loading and unloading mechanism is composed of electric winch, sub-frame, sliding bracket, and corner support wheel. When unloading the trailer, loosen the turn lock of the frame, install the corner support wheels on the side holes of the corner pieces of the container respectively. The hydraulic cylinder lifts one end of the subframe and the electric winch winds the wire rope to move the container together with the sliding bracket. After the corner support wheel at the rear of the container touches the ground, the sliding bracket stops moving backward and the tractor pulls the semi-trailer to run at a slow speed until the front of the container touches the ground. When loading, extend the sliding bracket under the front part of the container supported by the corner support wheel. In the gap, the wire rope head attachment hooks the container corner hole, and the electric winch winds the wire rope to pull the container onto the sliding bracket until the entire container is in position onto the frame. The disadvantage of this loading and unloading method is that it occupies a large area, takes a long time for self-loading and self-unloading, and requires an electric winch with a large drag force in Zambia.
The side loading and unloading method is to install a hydraulic control loading and unloading mechanism at both ends of the semi-trailer frame and use it to hoist the container on the side of the vehicle to the frame of the semi-trailer or hoist the container on the semi-trailer to the ground on the side of the vehicle. When driving, the hydraulic control loading and unloading mechanism is retracted so that the outer dimension is within the allowable vehicle outer dimension limit.
The side loading and unloading method is the most common loading and unloading operation method used by the container tipping trailer. In addition to the self-loading and self-unloading of the vehicle, it also has the function of stacking two-layer containers and loading and unloading adjacent vehicles.
Types of Container Tipping Trailer for Sale Zambia by Structure
According to the structure of the loading and unloading mechanism for container tipping trailer for sale in Zambia, it can be divided into folding hanger type and telescopic hanger type. According to the loading and unloading operation support mode, it can be divided into oblique support leg type and H-type telescopic support leg type.
Telescopic Hanger Type
The hanger and outrigger of the telescopic hanger type loading and unloading mechanism adopt telescopic structure, which are driven by hydraulic cylinders respectively, and the structure is compact. Due to structural limitations, the position of the hinge point on the luffing hydraulic cylinder is relatively low, which increases the force on the luffing cylinder. When the inclined support leg is used, the outrigger distance is short and the pressure on the ground is relatively large. Therefore, it is only suitable for self-loading dump trailer for shipping 20ft containers. When the H-type telescopic outrigger is used, the outrigger can be The overhang distance is increased so it is suitable for self-loading dump trailer for shipping 40ft containers. This H-type telescopic outrigger does not generate horizontal side-slip force, which is more beneficial to the work of the crew, but its horizontal and vertical telescopic legs are driven by two hydraulic cylinders respectively. Due to the structural arrangement requirements for container tipping trailer in Zambia, the vertical support hydraulic cylinder of the H-type outrigger is installed relatively high, the outrigger cannot be arranged in the same plane as the boom. The installation position of the outrigger needs to be specially set, thus increasing the length of the semi-trailer accordingly.
Folding Hanger Type
The folding hanger type loading and unloading mechanism for container tipping trailer in Zambia is divided into two types: telescopic outrigger support and retractable outrigger support. The folding boom type loading and unloading mechanism supported by telescopic outriggers is characterized by large lifting height and working range, which can stack two-layer of containers and load and unload adjacent vehicles. It can also be used for self-loading and self-unloading of 40ft containers. The folding hanger type loading and unloading mechanism supported by retractable outriggers is characterized by a simple structure, and the outriggers and booms can be arranged on the same level. The length of the trailer body is short, the weight is light, and the loading and unloading mechanism can be moved. This type can accommodate self-loading and self-unloading of 20ft and 40ft containers.
The power of the container tipping trailer can use the power of the tractor and the external power. An independent power station can also be added on the semi-trailer ifself.
