专用来源页列出:弹簧可调制动力矩 250–400 N·m、制动轮 300 mm、Ed30/5、65 kg、S1 及 S3-60%(1200 cycles/h),标准电源为 380 V 50 Hz 三相,可选 440–460 V 60 Hz。环境及防腐选项仍按来源条件理解。

Official YWZ9-300/E30A technical data
The dedicated source page states spring-adjustable 250–400 N·m torque, 300 mm brake wheel, Ed30/5, 65 kg, S1 plus S3-60% at 1200 cycles/h, standard 380 V 50 Hz three-phase supply and optional 440–460 V 60 Hz. Environment and corrosion options remain source conditions.
专用产品页提供明确以 mm 标注的字母尺寸。未作说明的 n=12 不纳入尺寸表,其含义和单位不作推断。

Dedicated product dimensions
Lettered dimensions are available with explicit mm units on the dedicated product page. The unqualified n=12 is excluded from the dimension table; its meaning and unit are not inferred.
专用页面将 E=1.0 mm 用作退距/间隙,并列出 F/G1/G2=255/130/295 mm。系列 A 型尺寸表则在尺寸表头下列出 E/F/G1/G2=255/130/295/330 mm。这四个符号的来源适用范围存在冲突。须分别保留两份来源并取得匹配的批准图纸,不以其中一页自动更正另一页。
来源原文(English)
E, F, G1 and G2 differ across manufacturer pages
The dedicated page uses E=1.0 mm retreat/clearance and F/G1/G2=255/130/295 mm. The series A-table uses E/F/G1/G2=255/130/295/330 mm under its dimension header. These four symbols have conflicting source scopes. Preserve both sources separately and obtain the matching approved diagram; neither page silently corrects the other.
制造商单页 PDF 列出以 mm 为单位的 YWZ8/YWZ9 衬垫尺寸及磨损限值,其中包含 YWZ9-300 行。这是衬垫部件资料,不能确认 YWZ9-300/E30A 的衬垫材质、BOM 或装配适配性,图号及批准版次亦未确认。

Official brake-lining PDF — company reference
A one-page manufacturer PDF lists YWZ8/YWZ9 lining dimensions and wear limits in mm, including a YWZ9-300 row. This is a lining component reference; it does not confirm the lining material, BOM or fitment of YWZ9-300/E30A. No drawing number or approved revision is established.
针对订购的 A 型版本,索取带图号/版次的图纸、批准的接口、衬垫材料,以及磨损补偿和释放/监测选项。来源将其描述为非危险区域使用的工作制动器,尚未确认其适用于纯保持用途或防爆场合。

Approved brake drawing and selected options
Request the numbered drawing/revision, approved interfaces, lining material, wear-compensation and release/monitoring options for the ordered A-version. The source describes a service brake for non-hazardous areas; holding-only or explosion-protected suitability is not established.
Request a serial/nameplate photo, the applicable brake and Ed30/5 instructions, electrical configuration and product/batch-linked inspection records. Original image publication rights remain unconfirmed.
The dated YWZ9 series manual lists A=590 mm and ambient -25 to +50 C for 300/E30A; the dedicated current product page lists A=630 mm and -20 to +50 C. The measurement definitions, revision and selected configuration have not been reconciled. Obtain the manufacturer-approved drawing and operating conditions for the offered unit before installation.
