Problem
|
Clamshell Grab Solution
|
|---|---|
|
Shovels too slow for coal/sand
|
Two shells close like jaws – grabs 1–6 m³ per cycle. One button = full load
|
|
Material spills during travel
|
Tight seal when closed – zero spillage, even for fine sand/grain
|
|
Need fast loading/unloading
|
10–15 cycles/hour → moves 80 tons/hour (vs. 10 tons/hour by shovel)
