Introduction of GB/T 35205.6-2023

GB/T 35205.6-2023 Rough-terrain trucks - Safety requirements and verification - Part 6 : Tilting operator's cabs 1 Scope This document specifies safety requirements and means of verification for tilting operator's cabs of trucks covered by GB/T 35205.1 and GB/T 35205.2, where the seat index point height (SIP) is lifted not more than 400 mm when the cab is fully tilted. See Figure 1. This document only deals with significant hazards, hazardous situations or hazardous events relevant to the tilting cab affixed to trucks. 2 Normative references The following referenced documents are indispensable for the application of this document.

In addition, the tilting operator's cab shall be designed according to the principles of ISO 12100 for relevant but not significant hazards which are not dealt with by this document. 4.1.1 Access With the tilting operator's cab in the lowest position, the access to the normal operating position shall comply with the following: - GB/T 35205.1-2017, 4.11 for variable reach trucks; - GB/T 35205.2-2017, 4.11 for slewing trucks. 4.1.2 Operator's seat The seat shall be designed to maintain the operator in the tilted position. 4.1.3 Tilting operator's cab The maximum tilting angle should not exceed 20°from the horizontal axis of the truck chassis. The tilting speed shall not exceed 5(°)/s under normal working conditions. Means shall be provided to prevent uncontrolled movement in case of hydraulic line rupture or interruption of the power supply. 4.1.4 Travel restrictions Provisions shall be made to prevent travel of the truck when the tilting operator's cab is not in the travel position as defined by the manufacturer.
