There are actually a range of security features which are common to certain kinds of trucks like seat belts on sit-down vehicles. On most stand-up vehicles there are dead-man petals as well. In addition, some manufacturers are providing more features like speed controls which could reduce the overall speed based on steering angle and load height.

Support and Service
Making certain you would maintain access to high levels of support and service is a very important part of lift truck selection. There seem to be a range of new players within the lift truck industry each and every year. Although they provide a nice price and a decent lift truck design, if they do not provide the local or regional service and support infrastructure, you must be ready for major stress when the lift truck breaks. Every type of lift truck goes down eventually and service, parts and general questions must be addressed at some point.
You would usually want to have a nearby dealer or repair shop with a complete supply of the parts you need for your specific unit. Be sure to visit the repair shop or the dealership and check their parts room so as to try to know how many parts they stock. Make certain to ask that if they do not have the part you require, where will it come from? Hopefully, the answer would be from a local or regional distribution facility.
Try to get some additional ideas on the models currently used in your vicinity. This is doubly important for specialty trucks like turret trucks. If there are only a small amount of trucks being used in their service area that you must assume they may not be stocking many if any parts for them. Also, they may have very little overall experience in servicing that model as well.
