GB/T 18849-2011

📋 Scope / 适用范围 ai_extracted

This standard specifies the performance, test methods, control systems, control forces, and component strength of braking systems installed on the following industrial vehicles as defined in ISO 5053: — Powered industrial trucks of various lifting capacities/load capacities; — Industrial tractors with a rated tractive force not exceeding 20,000 N; — Burden carriers; — Powered industrial trucks for container handling. This standard does not apply to braking in the event of a power failure or any other auxiliary power failure, nor to braking in emergency situations (e.g., activation of emergency switches or shutdown of control systems). This standard applies to industrial vehicles (hereinafter referred to as "vehicles") manufactured after the publication of this standard.
