A modern-day, boom-equipped truck operates on the same principle as the basic ? .
lever
A modern-day, boom-equipped truck is a labor saving device because ? .
it requires fewer workers to perform a given task
The Archimedes Principle states that the weight of an object will increase in proportion to the distance that it moves from the fulcrum point.
False
The load charts for a bucket truck should be located ? .
at the boom tip
A boom-equipped truck can tip over even if there is no weight at the end of the boom.
True
The way the truck is set up prior to using the boom will not affect the load capacity of the boom during normal operation.
False
The boom must not be operated if the truck is at an incline of more than ? .
5°
Placing outrigger pads under the outriggers can help prevent ground penetration.
True
The total weight of the load is equal to the weight of the object being lifted.
False
The purpose of the hydraulic overload protection (HOP) system is to protect the unit from ? .
structural overload
An object that is attached or frozen to the ground can be safely lifted after factoring in its true weight to the load calculation.
False
As the radius of the boom changes, so does its capacity.
True
The required load charts for the equipment in use must be posted at the point of operation.
True
When calculating loads to be moved with a jib, it is necessary to check both the jib capacity chart and the main boom chart.
True
There are ? basic types of pin plates used in jib positioning.
