You can't go wrong with Westminster hyd.!! I can say first hand that your project will not leave their shop until it is right, Rick Cooney was nice enough to allow me to spend time in his shop while they were building my truck, the men that work with him take pride in their work and they go the extra mile so that you have a truck and crane combination that will last for many years!!
One thing Rick offers is an automatic greasing system for the crane I did not include it in my build and i am kicking myself now ! If you are looking to get a kboom your search is over, this is a one stop shop they do it ALL . I had one leaking hose and Palfinger is right there to cover it under the warranty . Rick always extends the offer to call him and you will get HIM on the phone, if by chance he is out of the shop he makes it a point to call you back by the end of the day .
