ASME B56.5:2004 pdf free download.Safety Standard for Guided Industrial Vehicles and Automated Functions of Manned Industrial Vehicles.
ASME B56.5 defines the safety requirements relating to the elements of design, operation, and maintenance of powered, not mechanically restrained, unmanned automatic guided industrial vehicles and automated functions of manned industrial vehicles. It also applies to vehicles originally designed to operate exclusively in a manned mode but which are subsequently modified to operate in an unmanned, automatic mode, or in a semiautomatic, manual, or maintenance mode.
This Standard applies to guided industrial vehicles in automatic mode of operation in nonrestricted areas. Portions of this Standard, when designated, also apply to semiautomatic, manual, and maintenance modes and restricted areas of vehicle operation. It is recognized that restricted areas may exist, and require the user and/or manufacturer to determine appropriate safety provisions.
Portions of this Standard, when designated, also apply to automated functions of manned industrial vehicles.
This Standard does not apply to passenger-carrying vehicles.
2 PURPOSE
The purpose of this Standard is to promote safety through the design, construction, application, operation, and maintenance of unmanned guided industrial vehicles and automated functions of manned industrial vehicles.
This Standard may be used as a guide by governmental authorities desiring to formulate safety rules and regulations. The Standard is also intended for voluntary use by others associated with manufacturing or use of unmanned guided industrial vehicles and automated functions of manned industrial vehicles.
(2) For emergency operation, the maximum deceleration rate shall be commensurate with emergency stop dynamic criteria. See para. 4.3.1.
(d) Monitorinc. Loss of speed control shall require an emergency stop.
8.7.2 Steering. Steering characteristics shall not degrade vehicle dynamic stabilib
8.7.3 Ramps
(a) Definition. A variation in floor grade in excess of 3% and of a length where rating data variance is required shall constitute a ramp. See para. 8.171(a).
(b) Speed Control. Means shall be provided to control vehicle speed on ramps consistent with the application. Vehicle travel speed and safe speed limit on ramps shall be agreed to by the manufacturer and user as part of system parameters. Vehicles rated for ramp operation shall have provisions for starting and stopping on ramps.
(c) Braking. Controlled braking means shall be provided on vehicles which are designated for automatic ramp operation. Emergency braking performance shall be the same as for level horizontal operation. See para. 8.8.1.
8.7.4 Stability. For vehicles with lift of more than
300 mm, the stability requirements of ASME 1356.1 shall apply. For vehicles with lift of 300 mm or less, the stability requirements of ASME B56.8 shall apply.
8.8 BrakIng Functions
8.8.1 Vehicles shall have the following braking functions. Multiple functions may be provided by a single braking means.
(a) Emergency Brake. Emergency braking shall be provided for all vehicles. The emergency brake shall be mechanically set and require power or force from a source external to the brake to release. During automatic operations, this brake may be automatically actuated and deactuated. The prime consideration is that the emergency brake shall cause the vehicle to stop prior to impact between the vehicle structure and the obstruction.
(b) Parking Brake. A parking brake, which may be a part of or include the service brake or emergency brake, shall be provided. When a vehicle is stopped, this brake should be applied to prevent inadvertent movement of the stationary vehicle.
(c) Service Brake. A service brake, which may be a part of or include the parking brake or emergency brake, shall be provided. During manual operation, this brake is used for slowing or stopping the vehicle.
8.8.2 Controlled braking may be provided. Controlled braking is a means for slowing or stopping the vehicle. This may be accomplished by electrical or mechanical means.
