we have actually built cranes for them. what we have done for our own facility is purchase the hoist, the end trucks and the electrical stuff and prints, then fab the crane ourselves. it's very easy and saves a lot of money. i do like the variable speed on the motors, makes for smooth operation. mechanically we have not had any problems.

We use them on manual beam trolly electric hoist.  They are really good from a service standpoint, and also keep great inspection records so we are always OSHA compliant.
