Aerial manoeuvres
What is elevation?
Raising the ladder through an arc
Aerial manoeuvres
What is depression?
To lower the ladder through an arc
Aerial manoeuvres
What is extension?
To increase the length of the ladder
Aerial manoeuvres
What is housing?
To decrease the length of the ladder
Aerial manoeuvres
What is training?
To rotate the turntable to the left or right
What do all aerial appliances have, that can aid in getting an injured casualty down to ground level?
Stretcher
What is the difference between ‘rest down’ and ‘bridge’, on a turntable ladder pitch?
Rest down is when the cage rests onto a surface, to allow access, whereas bridge is allowing access at a 90° angle, such as through a window, therefore the cage isn’t resting on a surface
What are the benefits of a TL?
Six answers
Quickest to setup and deploy
Longest reach of any LFB aerial
Can rest in buildings to create a rough staircase for up to 12 people
Can be used (with restrictions) in winds up to 60mph
Low level jack beams allowing easier deployment
Detachable floodlights
What are the benefits of an ALP?
Five answers
4 person cage capacity
Highest quantity of water delivery
The articulated tip boom allows the ALP to reach over parapets
Wheelchair access
Rear wheel steering for increased manoeuvrability
Benefits of the HP?
Two answers
6 person cage capacity
Can be used (with restrictions) in winds up to 50mph
What should be done if communications break down between the head of the ladder and the base operator?
The cage should be withdrawn from the hazard area
