RSP Crane Types & Operational Limits

Question 1

Which crane type uses a horizontal boom that can rotate 360 degrees and is mounted on a wheeled carrier?

Accepted Answer

Mobile hydraulic crane

Answer

A mobile hydraulic crane is mounted on a wheeled carrier with a boom that can rotate 360 degrees, allowing repositioning without dismantling.

Question 2

What document specifies the maximum load a crane can lift at various radii and boom angles?

Accepted Answer

Crane load chart

Answer

The crane load chart (also called a capacity chart) specifies the maximum allowable load at each combination of radius, boom length, and configuration.

Question 3

A crawler crane differs from a mobile crane primarily because it:

Accepted Answer

Travels on tracks instead of rubber tires

Answer

Crawler cranes travel on steel tracks (crawlers), which distribute load over a larger footprint and allow movement while under load.

Question 4

When operating a crane near its maximum rated capacity, the operator should primarily consult:

Accepted Answer

The load chart for the exact boom length and radius

Answer

The load chart provides the exact rated capacity for the current boom length, radius, and crane configuration, which must be followed to prevent overloading.

Question 5

What is the primary purpose of outriggers on a mobile crane?

Accepted Answer

To stabilize the crane and increase its lifting capacity

Answer

Outriggers extend from the crane's lower works to provide a wider, more stable base, which increases tipping resistance and allows higher lifting capacities.
