Crosby Group Products ReferencePersonnel Platform – OSHA 1926.1431 and ASME B30.23Dear Crosby Customer,OSHA implemented revised rules for personnel lifting by use of a platformand a crane in the construction industry with the publishing of the final rule1926.1431(g)(1)(i)(A) and 1926.1501(g)(4)(iv)(B) Hoisting Personnel.ASME has developed ASME B30.23 under the procedures of ANSI. ASMEB30.23 establishes the design criteria, equipment characteristics andoperational procedures which are required when material handling equipment,as defined by the ASME B30 Standard, is used to lift personnel.Based on a review of these documents, Crosby is providing recommendationson the use of our products to meet both the OSHA and ASME requirements.Crosby does not recommend when personnel can be lifted or not. Ourrecommendations relate to the use of our products when the decision is made.The Market Leader: Yesterday, Today and Tomorrow“Crosby: There is No Equal”Copyright 2015 The Crosby Group LLCAll Rights Reserved

A falling load may cause serious injury or death. Hook must always support the load. The loadmust never be supported by the latch. See OSHA Rule 1926.1431(g)(1)(i)(A) and1926.1501(g)(4)(iv)(B) for personnel hoisting bycrane or Derricks. A Crosby S-319N, S-320N,S-322N, S-1327, and A-1339 Hook with an S-4320latch attached (When secured with cotter pin)may be used for lifting personnel. An S-4320 Latch is only to be used with a CrosbyS-319N, S-320N, S-322N, S-1327, and A-1339 Hook. DO NOT use this latch in applications requiringnon-sparking. Read and understand these instructions beforeusing hook and latch.WARNING ANDAPPLICATIONINSTRUCTIONS Always inspect hook and latch before using.Never use a latch that is distorted or bent.Always make sure spring will force the latch against the tipof the hook.Always make sure hook supports the load. The latch mustnever support the load. (See Figure 1 & 2.)When placing two (2) sling legs in hook, make sure theangle between the legs is less than 90 and if the hook orload is tilted, nothing bears against the bottom of this latch.(See Figure 3 & 4.)Latches are intended to retain loose sling or devices underslack conditions.Latches are not intended to be an anti-fouling device.When using latch for personnel lifting, select proper cotterpin (See Figure 5). See Step 7 below for proper installationinstructions. Never reuse a bent cotter pin. Never use a cotter pin with a smaller diameter ordifferent length than recommended in Figure 5. Never use a nail, a welding rod, wire, etc., in place ofrecommended cotter pin. Always ensure cotter pin is bent so as not to interferewith sling operation. Periodically inspect cotter pin for corrosion andgeneral adequacy.Figure 5RIGHTWRONGRIGHTWRONGFigure 1Figure 2Figure 3Figure 4Hook IdentificationCodeDFGHIJKLNRecommendedCotter Pin † The current SS-4055 latch kit and the PL latch will not fit new 319N, 320N, or322N hooks.
