Final answer:
The dangerous forklift described is the Articulated Forklift, which has a solid front axle and uses a pivot pin for sharp turns. Operators must exercise caution when entering or exiting to prevent accidents.
Step-by-step explanation:
The correct answer is option Articulated Forklift. The machine described is an articulated forklift, which is designed with a solid front axle and a pivot pin that provides the forklift with the ability to make sharp turns by pivoting its front end.
This articulation can indeed be hazardous when an operator is climbing in or out of the forklift, as it can cause unexpected movement.
It is critical for operators to be fully trained on the safe operation of this type of forklift and to ensure that the vehicle is stationary and secured before disembarking to minimize risk.
In terms of mechanics, the use of hydraulic and mechanical lever systems enhances the machinery's efficiency and ability to handle heavy loads with precision.
The correct answer is option Mechanical lever systems are used in heavy machinery such as forklifts. They allow the front end to pivot when turning the steering wheel, making it potentially dangerous when climbing in or out.
This is known as a pivot pin and it is an important feature in forklift design.
