Bhutan Model 81 Silent Breaker Rock-Breaking Feedback
Customer video shows a model 81 silent breaker working on a large rock in Bhutan. The source table maps it to a 140 mm tool and 20–25 t class.
What the Customer Feedback Confirms
The source folder identifies this as Bhutan customer feedback for a model 81 silent breaker. The customer-supplied worksite video shows an enclosed yellow hydraulic breaker mounted on an excavator and striking a large rock in a mountainous outdoor site.
The LICHI source table maps model 81 to a 140 mm tool and a 20–25 tonne excavator class. The exact carrier brand, carrier model, oil flow, pressure and bracket dimensions are not included in the approved public record, so they are not inferred from the video.

Why Rock Work Needs More Than a Tonnage Match
A 20–25 tonne carrier class narrows the model range, but hard-rock work also requires confirmation of oil flow, pressure, tool shape, carrier stability and the way the operator can position the chisel. The rock type and whether the job is primary breaking, secondary breaking or road excavation should be stated before the tool is selected.
An enclosed silent housing can provide external protection and a different noise profile, but body style does not replace hydraulic matching. The quotation should record the proposed breaker, tool diameter, hydraulic inputs, mounting basis and any data still waiting for confirmation.
Checks for a Similar Mountain or Rock-Breaking Order
- Full excavator model, operating weight and machine nameplate.
- Auxiliary oil flow, working pressure and relief setting.
- Rock type, boulder size and the intended breaking method.
- Worksite access, slope and positioning constraints.
- Bracket or quick-coupler dimensions.
- Chisel type, lubrication plan and bushing inspection route.
- Starter spare parts for the confirmed breaker model.
- Destination port, packing and required support files.
Evidence Boundary
The source material does not provide a measured production rate, total working hours, service interval, fuel figure or written customer quotation. This page therefore documents visible operation and the confirmed model class without turning one short video into a performance guarantee.
Review the WW-140 silent breaker route for the related product class. Then send the actual excavator and hydraulic data using the breaker matching guide.
