Tire Type:
Solid pneumatic tires are common; cushion tires may also be available.
Safety Standards:
Designed to meet ANSI/ASME B56.1 safety standards for powered industrial trucks.
Operator Presence System:
Typically includes an operator presence sensing system that disables travel and hydraulics when the operator leaves the seat.
Overhead Guard:
Standard overhead protective structure (OHS) to protect the operator from falling loads.
Forks And Load Backrest:
Standard forks and a load backrest extension to prevent loads from shifting towards the operator.
Features:
Basic instrumentation panel (fuel gauge, temperature gauge, hour meter, warning lights). No advanced infotainment systems typical of passenger vehicles.
Features:
