Query: Very good for a simple flash, very bad for a flashpoint

I use a lightsand for about a year with a simple flash and an umbrella, and works very good.I bought another one for a Flashpoint Model II 320A Monolight 150 Watt Second Strobe.But the second time I used the lightstand with the Flashpoint and the umbrella, the lightstand broked down.Fortunately the Flashpoint was protected by the umbrella.Do not use with a Flashpoint or something heavy!
