ASME B30.25:2003 pdf download.SCRAP AND MATERIAL HANDLERS.

(d) On wheel-mounted handlers, the travel and steering mechanism shall be designed to permit a controlled stop in the event of the 1065 of engine power.

25-1.4.2 Travel Brakes

(a) Rail-mounted handlers shall be equipped with brakes capable of bringing the handier to a stop while descending the maximum

grade recommended for travel. In addition, means shall be provided to engage brakes manually. Such engagement means shall be ca

pable of holding the handler stationary on the maximum grade recommended for travel, and shall remain engaged in the event of loss of power.

(b) Crawler-mounted handlers shall be equipped with a service brake system, a secondary brake system, and a parking brake system

that meet the brake performance requirements specified in ISO 10265. The brake system.s may use common components; however, in the event of a failure of any single component, the remaining brake system(s) shall provide handler stopping capability meeting the

secondary brake system performance requirements specified. After being applied, the parking brake system shall not be dependent

upon an exhaustible energy source.

(c) Wheel-mounted handlers shall be equipped with a service brake system, a secondary brake system, and a parking brake system and meet the brake performance requirements defined in ISO/SAE J3450. The brake systems may use common components; however, in the

event of a failure of any single component other than a tire, the remaining brake system shall provide handler stopping capability meeting the secondary brake system performance requirements specified. After being applied, the parking brake system shall not be dependent upon an exhaustible energy source.

(d) Prior to being placed in service, all new or modified handlers shall be tested by the manufacturer or assembler/modifier to

verify that the brake systems meet the specifications in paras. 25-1.4.2(a), (b), and (c).
