Hyster H50XL:
Brakes stuck

After setting parking brake and then releasing it, then gas pedal is pushed, takes some throttle and then a clunk and truck starts to move. What could it be??

could be a frozen park brake cable
also could be a misadjusted wheel, self adjusters are not always 'self adjusting' or they tend to over adjust and tighten up if hardware is not right inside.
then again they might just be worn out so badly and hub is grooved out and the shoes are just stuck inside the groove while they are adjusted up.

if you can get the wheel to turn as you say, then try this
these trucks do not adjust from the backing plate side... you have to pull the wheel and get access to the adjuster from the hub side through a hole in the hub so.....
pull the wheel, get a prybar or something to put between the studs and force the hub around till the access hole is lined up with the adjuster at the bottom.
Then deadjust the wheel as far as you can get it
the wheel should come off then.

A note: about the park brake cables...
they connect on the back side of the backing plate to a cantilever/essentric style splined stud, you can just unhook the cable by loosening the bolt on the yoke assy and slide it off the stud at that point and relieve the pressure from the stuck cable (if this is the case)

Sounds to me like the parking brake cable is frozen and not releasing the brakes......going to have to work at it to get the drums off...recommend replacing both park brake cables and shoes....wouldnt be a bad idea to replace wheel cylinders adjusters and hardware while in there.....

Fact of the week

John Lennon had terrible eyesight and was very self-conscious about it. Early in his career, he would not wear his glasses during performances. In the end, John's 'granny glasses' became one of his most iconic trademarks. His last pair, worn on that tragic day in 1980, are kept at 'The Beatles Story' exhibit in Liverpool, insured for over £1 million.
