i think there are a few of you that do not understand what the terms mean in terms of dealing with what manufacturers develop and sell for each model lift they make.
It was explained in my first post and that has not changed for years.
Manufacturers like hyster , yale, cat, any of them all design a model lift and generally they offer 2 options on each model to make the lift more palletable for customers buying them depending on the budget they have for purchasing a new lift.

- a standard model with basic systems
- a premium model with other options they can offer for improved performance or operator comfort and ergonomic comfort.

example: an electric lift can come with standard drive system and controls and contactor controlled hydraulics and basic dash panel with no options for operator access to the system, a standard seat with standard seatbelt. OR...
it can come with standard or high performance drive system and controls WITH hydraulic controller, all sensors for motors, a cushion suspension seat with adjustments and seatbelt with operator presence control incorporated into the circuits, ie: wired into the system, a premium dash panel that does allow for operator or tech access through the dash and will have customization settings that can be set by the operator or fine tuned by the tech servicing it. The drive motors will be either a standard 9" motor or an 11" motor for high performance (yale offers this option in their sit down electric trucks). Cat and hyster and other brand lifts have similar options.
ALL manufacturers are very competitive so you will see very similar options on each brand lift made no matter who manufactures it.

These are just examples of different options trucks are built with and will vary depending what the customer orders on the machine when it is sold.

these would be the differences you would see between a standard truck and a premium truck.
