分数是本图鉴内的相对0–100分。用于浏览，不是工程规格。
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.
Bulldozer的推进、结构、控制与安全在同一运行包线内耦合。先分清各系统名称与职责，便于故障模式与合规审查。
下方仪表为设计裕度、可维护性与人因的相对评分，用于同级平台比较。
系统
车身·载荷路径
就Bulldozer而言，Sealed and lubricated track links with idlers, sprockets, and rollers spread machine weight over soft ground. Track tension and shoe width set ground pressure and flotation on sand or mud.
推进·动力
就Bulldozer而言，Push blade mounts on a C-frame with hydraulic lift, tilt, and angle cylinders. Cutting edge and end bits are consumables; pitch cylinders adjust penetration on hard fill.
制动·能量回收
就Bulldozer而言，Turbocharged diesel drives a torque converter and powershift or hydrostatic transmission to final drives at each sprocket. Low-speed lugging torque defines dozer class more than road speed.
车载网络
就Bulldozer而言，Load-sensing pumps feed blade, ripper, and auxiliary circuits. Joystick pilot controls modulate flow for fine grading versus full push loads.
乘员安全
就Bulldozer而言，FOPS/ROPS cab with AC and pressurization keeps dust out; rear and blade cameras assist blind-side work near haul roads.
热管理
就Bulldozer而言，Single or multi-shank ripper mounted on the rear beam breaks compacted rock or frost ahead of blade passes.
相对量表
热点
就Bulldozer而言，Track link pins
就Bulldozer而言，Worn pins elongate pitch and derail tracks under side load on slopes.
就Bulldozer而言，Final drive seals
就Bulldozer而言，Planet gear oil leaks contaminate 制动s and destroy internal gears.
就Bulldozer而言，Cutting edge wear
就Bulldozer而言，Rounded edges slip rather than cut, raising fuel burn and cycle time.
就Bulldozer而言，Hydraulic cylinder rods
就Bulldozer而言，Scored rods from dust ingress cause seal failure and blade drift.
就Bulldozer而言，Turbocharger coking
就Bulldozer而言，Low-RPM high-load operation without cool-down clogs turbine passages.
材料
就Bulldozer而言，Through-hardened track shoes
就Bulldozer而言，Quenched steel shoes resist abrasion on rocky sites.
就Bulldozer而言，High-strength blade steel
就Bulldozer而言，Curved moldboards combine yield strength with weld repairability.
就Bulldozer而言，Chromium facing edges
就Bulldozer而言，Hard-facing on cutting edges extends change intervals.
就Bulldozer而言，Biodegradable hydraulic oil
就Bulldozer而言，Some sites mandate env-friendly fluid for leaks near waterways.
