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

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.
