ASME B56.5:2004 pdf download Safety Standard for Guided Industrial Vehicles and Automated Functions of Manned Industrial Vehicles
GENERAL SAFETY PRACTICES
4.1 Introduction
4.1.1 Before putting a guided industrial vehicle sys-tem into service,the user shall be responsible for allfactors affecting the operation and maintenance, as referenced in Part Il of this Standard.
4.1.2 Guided industrial vehicles can cause injuryor damage if improperly used or maintained.4.1.3 Part Il contains safety standards applicable tovehicle operations.Unusual operating conditions mayrequire additional safety precautions. Guided industrialvehicles which can be operated by manual controls mayhave restricted operational characteristics.
4.1.4 Part IV contains safety standards applicable toautomated functions of manned industrial vehicles.
4.2 Modifications，Nameplates，Markings,Capacity,and Stability
4.2.1 Except as provided in para. 4.2.2, no modifications or alterations to a guided industrial vehicle, whichmay affect the capacity, stability, or safe operation of thevehicle shall be made without the prior written approvalof the original vehicle manufacturer or its successorthereof,When the vehicle manufacturer or its successorapprove a modification or alteration, appropriatechanges shall be made to capacity plates, decals, tagsand operation and maintenance manuals.
4.2.2 In the event that the vehicle manufacturer isno longer in business and there is no successor in interestto the business, the user may arrange for a modificationor alteration to a guided industrial vehicle, providedhowever, the user shall
(a) arrange for modification or alteration to bedesigned, tested, and implemented by an engineer(s)expert in guided industrial vehicles and their safety:
(b) maintain a permanent record of the design, test(s)and implementation of the modification or alteration;
(c) make appropriate changes to the capacity plate(s)decals, tags, and operation and maintenance manuals;and
(d) affix a permanent and readily visible label on thevehicle stating the manner in which the ehicle hasbeen modified or altered together with the date of themodification or alteration, and the name of the organiza-tion that accomplished the tasks.
4.2.3 The user shall see that all nameplates and caution and instruction markings are in place and legible
4.2.4 When utilizing lifting equipment such as elevators, cranes, ship hoisting gear, etc., to relocate a guidedindustrial vehicle, the user shall assure that the capacityof the hoisting equipment being used is not exceeded
4.2.5 The user shall consider that changes in load(s)load position(s),or dimension(s)coupling types(s) orposition(s), and floor surface condition(s) or batteryweights may affect rated capacities and safe operationOnly stable or safely arranged loads shall be handled
4.2.6 The user shall be responsible for the load stability and retention, When deemed necessary by the userverification shall be required.
4.2.7 Some users may decide to establish, for theitown use, stability requirements that will vary from thosein para. 8.7.4. However, the requirements in para.8.7.4should serve as a guide for the user, working with themanufacturer, in establishing his own more stringentrequirements.
4.3 Stopping Distance
4.31 The determination of the vehicle’s stoppingdistance (whether used as a load carrying vehicle or atow vehicle) depends on many factors, such as othervehicle and pedestrian traffic, clearances, condition ofthe floor, and stability of load(s). The prime consideration is that the emergency braking system shall causethe vehicle to stop prior to impact between the vehiclestructure and the obstruction.
4.3.2 Caution should be exercised with changedenvironments. Changes in weather, surface conditionsor applications may affect the vehicle stopping distancespeeds, loads, brake settings, and/or operation shouldbe adjusted accordingly.
4.4Sensors
If a load exceeds the width and/or length of the vehicle, the user should require that sensors in the directionof travel covering the maximum moving width and/orlength be provided to prevent contact between the loadand any obstruction.
