Coal industry to benefit from new bins

In response to a renewed demand for coal by South Africa’s government and Eskom to replenish the country’s stockpiles following last year’s electricity shortage, Bell Equipment has introduced specialised coal bins and high volume haulers.

According to Bell Equipment marketing manager, Stephen Jones the company launched these niche products after seeing a need in the market place for companies to increase their coal output, while at the same time reducing the capital expense of their operations.

Currently the company has low-density coal bins designed for the flagship B50D and the B40D and is designing a similar bin for the B30D.

“The coal bins are fitted with a tail gate and have significantly larger heaped capacities. In the case of the B50D coal bin the volumetric capacity has been increased by 46% from 28.7 m3 to 42 m3. Similarly the B40D bin has been increased by 41% from 23.4 m3 to 33 m3,” Jones says.

Bell Equipment’s new low-density coal bin. The B50D is fitted with a tail gate and the volumetric capacity has been increased by 46% from 28.7 m3 to 42 m3.

The proposed B30D coal bin will have a heaped capacity of 26 m3, which is a 47% increase in volumetric capacity compared to the 23.4 m3 of the standard bin.

“The design process parameters of the coal bin had to ensure that the standard truck geometry was retained, such as the standard chassis, tip cylinders, chassis load points and axle weights. These parameters ensure that the full factory warranty and ADT resale value is maintained by simply refitting a standard bin for resale or transplanting the bin to a new base carrier at the time of trade-in,” Jones explains.

Importantly the centre of gravity of all trucks fitted with a coal bin has not changed and stability has not been adversely affected.

The on-board weighing system, which Bell Equipment pioneered on factory-built trucks, monitors the load to ensure that the gross weight does not exceed the rated specification. This promotes the effectiveness of the braking and retardation systems.
