Question 1

Under BS 7121 and UK LOLER 1998, what is the primary operational distinction of an All-Terrain (AT) mobile crane compared to a Rough-Terrain (RT) mobile crane?

All-Terrain cranes are road-legal for high-speed highway travel and feature multi-axle crab/all-wheel steering, whereas Rough-Terrain cranes are restricted to site-only use. Rough-Terrain cranes feature multi-telescopic lattice booms suited for high-rise lifts, whereas All-Terrain cranes only use fixed pin-jib booms. All-Terrain cranes do not require outriggers when lifting at maximum capacity, whereas Rough-Terrain cranes must always be fully extended. Rough-Terrain cranes are exempt from LOLER 1998 thorough examinations due to their off-road design classification.

Correct Answer:

All-Terrain cranes are road-legal for high-speed highway travel and feature multi-axle crab/all-wheel steering, whereas Rough-Terrain cranes are restricted to site-only use.

Question 2

When traveling a mobile crane on public highways in the UK under STGO (Special Types General Order) regulations, what must the crane operator verify regarding counterweights and boom position?

The boom must be fully retracted, rested in the travel bracket, and axle load limits strictly compliant with STGO category restrictions. The boom must be extended to 50% length with counterweight suspended to balance rear axle pressure. The fly jib must be fully rigged and offset at 30 degrees to reduce overall transport length. Outriggers must be extended 0.5 meters outward to provide lateral stability during high-speed cornering.

Correct Answer:

The boom must be fully retracted, rested in the travel bracket, and axle load limits strictly compliant with STGO category restrictions.

Question 3

What is the core function of crab steering mode on a multi-axle All-Terrain mobile crane?

To steer all wheels in the same direction, allowing the crane to move diagonally into tight site positions. To lock the front axles and steer only the rear axles for high-speed highway cornering. To turn front and rear wheels in opposite directions to minimize the turning circle radius. To automatically adjust outrigger extension lengths while driving across uneven muddy terrain.

Correct Answer:

To steer all wheels in the same direction, allowing the crane to move diagonally into tight site positions.

Question 4

A mobile crane is configured with crab steering, independent rear steering, and front-wheel drive options. When maneuvering on public roads, which steering mode is legally mandatory?

Front-wheel (highway) steer mode with rear axle steering locked in the straight-ahead position. Full crab steer mode to allow rapid lane changes on motorways. Coordinated all-wheel steer mode active at all speeds above 30 mph. Manual rear-steer override activated continuously by the operator.

Correct Answer:

Front-wheel (highway) steer mode with rear axle steering locked in the straight-ahead position.

Question 5

What main advantage does a Rough-Terrain (RT) mobile crane offer over a conventional truck-mounted crane when working on unpaved site ground?

Large oversized flotation tires, high ground clearance, and four-wheel drive capability for soft ground mobility. Higher road speed capabilities enabling inter-city travel without transport low-loaders. Greater main boom length exceeding 100 meters without requiring counterweights. Automatic levelling outriggers that do not require ground matting.

Correct Answer:

Large oversized flotation tires, high ground clearance, and four-wheel drive capability for soft ground mobility.
