Batasan Beban Pada Dump Truck Eps. 2 - Serial Analisis Pembebanan Alat Angkut

Main Ideas

The video explains how to determine whether a dump truck’s load is within permitted limits. It builds on the previous episode, which identified the truck’s load components:

• Cabin and chassis
• Vessel/body
• Payload
• Operator

Adding these components gives the total load. The calculation can also show the loads on the front and rear axles.

Comparing the Load with GVW

The total is compared with the truck’s gross vehicle weight (GVW), which the video uses as the truck’s load limit:

• A total below GVW is an underload.
• A total above GVW is an overload, although the manufacturer may permit a limited overload tolerance.

Overload Tolerance

Overload tolerance varies by truck and must follow the manufacturer’s recommendation. The presenter gives examples of tolerances ranging from 20% to 30% for some trucks, and cites a 10% limit for an HD785 based on its manual.

Tolerance may be calculated as a percentage of payload or GVW; the presenter says it is commonly calculated as a percentage of GVW. Loads must not exceed the manufacturer’s maximum permitted tolerance.

Minimum Load

The presenter cites Indonesia’s Ministry of Energy and Mineral Resources Decree 1827/2018, Attachment 2, page 137, point 2(c), as requiring a minimum load of 90% of GVW.

According to the video, a load below 90% may be physically safer, but it is not permitted and results in inefficient use of the truck. Lower production may also reduce company profits and government tax revenue.

Practical Method

1. Calculate the relevant load components and add them together.
2. Compare the total with the truck’s GVW.
3. Check the manufacturer’s manual or contact the manufacturer to confirm the permitted overload tolerance.
4. Confirm that the load is:
   • At least 90% of GVW, and
   • No greater than GVW plus the manufacturer’s permitted overload tolerance.
5. Apply these limits during commissioning. An oversized vessel may push the truck above the upper limit, while an undersized vessel may prevent it from reaching the 90% minimum. Either condition may cause the truck to fail commissioning.

The next episode is expected to apply this analysis to a specific dump truck.
