I got a call the other day where a fire captain asked, “What are the maximum angles/percent grades it can track up and traverse?” These guys are running fuels reduction crews on the sides of some pretty steep hills in the west and it’s important to keep the teams and the equipment safe from slippage or damage.
The maximum operating slope for a track brush chipper is typically 30 degrees, though this can vary significantly based on the specific machine and working conditions.
In addition to safety concerns, the maximum slope question points to being mindful that the equipment isn’t angled in such a way that it reaches a point where the engine won’t be starved of oil. Of course, there are important factors that influence safe operation like; soil conditions, obstacles, etc. Are you tracking on firm ground, sandy dirt, concrete or mud? Each condition requires consideration and adjustment in how the incline is approached and traversed.
Here are some tips to consider when traversing steep inclines:
- Limit the slope angle: Do not exceed the maximum recommended slope angle of 30 degrees (70%). Rule of thumb is 30 degrees max intermittently and 15 degrees continuous
- Travel uphill: When moving the track chipper across a slope, orient the machine so the track end is facing uphill to improve stability and balance.
- Avoid diagonal movement: Do not travel diagonally across a slope, as this greatly increases the risk of the machine tipping.
- Make sure no one is standing or working in the area below the chipper that’s climbing an incline.
- Obstacles: Large rocks, stumps, or other debris can cause the machine to tip. A tracked chipper should not be operated near the unprotected edges of embankments or drop-offs.
Operator and operational safety
- Operator position: When tracking over a slope, the operator should remain on the “uphill” side of the machine for better control and safety.
- Best operators: Only allow highly skilled and experienced operators to work on steep slopes. Safe operation relies heavily on the operator’s skill and judgment.
- Travel speed: Keep your speed slow and steady on inclines.
- No passengers: Chippers are not designed for passengers. Do not allow passengers to ride on any part of the machine.
- Personal protective equipment (PPE): Always wear the appropriate PPE, including a hard hat, safety glasses, hearing protection, and tight-fitting clothing.
- Exclusion zone: Maintain a safety exclusion zone of at least 10 meters around the chipper to keep unauthorized personnel away.
In conclusion, safely using a track chipper on an incline requires careful attention to the machine’s capabilities, the terrain’s condition, and the operator’s positioning. Before you begin work on a slope, always conduct a thorough site assessment. The maximum recommended operating slope is a safety guideline, not a guarantee.
Be safe out there!
