Mobile Truck Loading System with Front End Loader Hopper
Mobile truck loading systems with built-in loader hopper are used for efficient dumping of materials by wheel loaders and filling bulk trucks. The system consists of a mobile platform, front end loader hopper, loading screw, telescopic loading chute, and dust collector. Screw conveyor can be brought to a horizontal position for easier and safe transport.
When mobile system placed near the desired bulk truck to be loaded, the screw conveyor is lifted to 45 º angle with the help of automatic screw jacks.
A bucket of wheel loader dumps material to the hopper of the system. Rugged enough to withstand incidental contact with the front end loader, the heavy-gauge hopper provides an ample supply of material for the high capacity screw conveyor to run continually as a front end loader replenishes the material.
Optional air jets are available to aid product flow inside the hopper and vibrator to ensure complete and quick flow of the material.
Material inside the hopper is then transferred by inclined screw conveyor to the top of the truck and discharged into the bulk truck through a loading bellow.
The dust created during the process is prevented by a dust collector which is connected to the loading bellow and front end loader hopper. Dust content in the air is trapped by filter units and resent to the hopper with the help of automatically operated pulse jet valves.
Material coming from the screw conveyor is discharged through the loading bellow. At the beginning of truck loading process, the chute is lowered and stops automatically when it reaches to the tanker inlet. Polyurethane coated discharge cone fits vessel inlet to prevent any dust emission during bulk truck loading. Material falls freely through the inner side of the bellow.
After bulk tanker filling is started, a built-in dust collector evacuates the air trapped in the vessel to increase the flow rate of the product . Dust content in the air is trapped by filter units and sent back to the hopper with the help of automatically operated pulse jet valves. The level sensor placed at the bottom monitors the product level in the tanker truck and stops loading when the truck is full. Loading bellow retracts to the top position automatically.
Loading bellow is used for safe and dust-free loading of bulk trucks.
The dust collection system captures the dust created during the emptying of big bags and the loading of tanker trucks. Once the dusty air is filtered, the clean air is thrown out and the dust collected inside the filter is transferred to the loader hopper. The whole system is connected to the wheeled mobile chassis that allows the transportation of the system to the desired location by a tow-bar, forklift, or vehicle.
When loading is completed, the screw jack lowers the screw conveyor automatically to the horizontal position when the system is to be moved to any other desired location.
Various Parts of the System:
Front End Loader Hopper
The material brought by a bucket of a wheel loader is discharged into the loader hopper. Then it is transferred to the screw conveyor. It has a capacity of 5 m3 and is made of ST-37 Carbon Steel. There is the option of having fluidizing air jets to aid product flow inside the hopper and also the optional vibrating engine to ensure the fluidity of the product.
The screw conveyor enables the transfer of the material conveyed from cyclone to tanker loading bellow. It can be brought to a horizontal position when the system is to be moved to another location.
It enables the movement of the screw conveyor and telescopic chute upwards and downwards. When the system is installed in the area, the screw conveyor is lifted to 45 º angle with the help of automatic screw jacks. When loading is over, the screw jack lowers the screw conveyor automatically to the horizontal position. 2 units work in parallel.
It is used for safe and dust-free loading of the bulk truck. Material coming from the screw conveyor is discharged through the loading bellow.
It is used to supply pressurized air needed to operate a dust collector. It has a max pressure of 6 bars.
Electrical Control Panel
There is an electrical panel to control the equipment in the system. The following components can be controlled from the electrical panel.
The Mobile Chassis
The whole system is connected to this wheeled mobile chassis that allows the transportation of the system to the desired location by towbar, forklift, or vehicle. It is made of carbon steel. It has 4 wheels and has swivel jacks to provide rigidity during truck loading.
