简短问答

这类交通工具要看哪些本地机构或走廊规则?

先看本地视角中的型式认定、营运许可与枢纽——不要假定一份全球清单。

Is this a buying guide?

No. Tool-Lifes /vehicles is an educational atlas. It explains history, systems and culture without affiliate rankings.

Are the scores official?

No. The six scores are relative editorial 0–100 marks across the 48 types on this site.

Where do the photos come from?

Lead images resolve from Wikimedia Commons via Wikipedia titles on the English masters, with licences recorded on the credits page.

Why metric units?

Metric is the default. Regional notes (US customary, local brand culture) appear in culture and market chapters.

How is this different from a wiki article?

Each type gets seven fixed-depth chapters, comparable scores and cross-type labs — structured for browsing, not a single freeform page.

安全运行Bulldozer需要按相同顺序追踪能量、信息与机械流。

CBTC、ERS等通用缩写保留,并在上下文中解释。

原理

就Bulldozer而言,Tractive effort vs weight

就Bulldozer而言,Blade load cannot exceed track-ground friction without track spin.

就Bulldozer而言,Ground pressure

就Bulldozer而言,Contact area and machine mass determine sinkage on soft fill.

就Bulldozer而言,Blade capacity curve

就Bulldozer而言,Optimal push distance balances blade fill against reverse time.

就Bulldozer而言,Torque converter stall

就Bulldozer而言,Continuous stall heats transmission fluid and derates power.

就Bulldozer而言,Slope stability

就Bulldozer而言,Center of gravity shifts uphill with raised blade—rollover margin shrinks.

图解

就Bulldozer而言,Push load path

就Bulldozer而言,发动机 torque to blade soil reaction.

就Bulldozer而言,Hydraulic blade control

就Bulldozer而言,Pilot joysticks modulate implement pressure.

运行步骤

01 就Bulldozer而言,Site walk & bench

就Bulldozer而言,Confirm utilities, slope limits, and dump/spread zones before first pass.

02 就Bulldozer而言,Blade setup

就Bulldozer而言,Set angle, tilt, and ripper depth for material type and haul direction.

03 就Bulldozer而言,Push pass

就Bulldozer而言,Maintain steady RPM; avoid spinning tracks that churn subgrade.

04 就Bulldozer而言,Spread & grade

就Bulldozer而言,Feather blade for finish layer; check grade with GPS or laser.

05 就Bulldozer而言,Reverse & reposition

就Bulldozer而言,Use counter-rotation turns sparingly on slopes to limit undercarriage stress.

06 就Bulldozer而言,Shutdown cool-down

就Bulldozer而言,Idle with low hydraulic load, then track tension and fluid checks.

硬性极限

就Bulldozer而言,ROPS/FOPS rating

就Bulldozer而言,Cab structure is certified—never modify or remove posts for visibility.

就Bulldozer而言,Maximum slope

就Bulldozer而言,Manufacturer tilt limits govern sidehill and downhill blade work.

就Bulldozer而言,Blade lift height

就Bulldozer而言,Raised blade raises CG; transport rules cap blade carry height on roads.
