about braking castors

From website http://www.alibaba.com/product-gs/30...showimage.html, there is one hospital bed explanation, THR-MB104E 2-crank manual Hospital Bed.

I have one question as follows:

there is not any brakes on the bed castors, how to immobilize the bed and don't let the bed move ? Of course, there is one "U" shape handle at the end of the bed, does putting up the "U" shape handle mean to let the bed move? and does putting down the "U" shape handle mean to immobilize the bed?

Thanks. Last edit by comnursesall on Jan 5, '11

thanks very much.I have another question about one hospital bed, I don't have image about this bed.This bed has a handle installed in the middle and side of the bed, this handle is very special, I still remember that pushing up handle or pushing down the handle means to lower down the bed head or elevate the bed head.There is one danger here, if you push down the handle, the bed head will drop down dramatically, it is dangerous for patient on bed. So, should be very careful to operate this kind of bed.I can't remeber very clearly, do you have experiece with this kind of bed, how to operate accurately?Thanks.
