They shal
16、l have swivel brakes unless by their design they are not eccentric when locked. The brake mechanism shall be designed in such a way that it can only be unlocked by a delberate action. The brake mechanism must effectively pre- vent any rotatlon of the wheel when a horizontal force of 0,30 kN is appll
17、ed through the vertical swivel axis of the castor as close as possible above the castor housing and in the rol 1 ing direc- tion of the castor. The full value of the specified service load Is to be taken Into account when testing the castor brakes. 7.1.3 Oesign load The maximum design load of castor
18、s given by the manufacturer shall be verified by a minimum of 5 control tests. The test load shall be 3 times the maximum design load derived from table 1. One line is taken from each of the five groups In table 1 to establish the maximum design load. The brakes being locked, an Initial vertical loa

20、e objects falling through. NOTE : A fencing Structure can be provided capable of preventing objects as small as brlcks from falling and may be combined with guardrail and toe board or can be an additional and separate component. 7.5.2.2 Handrail It shall be possible to flx a handrail in such a posit
21、lon that its top surface is 1000 t 50 nun above the level of the platform (see figure-5). 7.5.2.3 Intermodlate guardrail It shall be possible to fix a second guardrail, such that neither the space above and between it and the underside of the principal guardrail nor the space below and between it an
