One feature that is included in many new models of all terrain cranes is the load limit indicator (LMI). The load limit indication is a computerized indicator with several sensors all over the all terrain crane which alarm the operator when the crane is going over the load capacity. This system is very simple to use for each all terrain crane model. The operator enters the maximum load capacity into the system as well as the angle of the lift and the radius of the boom of the all terrain crane. The load limit indicator is then able to monitor the progress of the lift and alarm the operator when the machine is overloaded.
The all terrain cranes for sale today have usually one engine which powers the undercarriage and the crane itself only. The upper part of newer all terrain crane models is run by hydraulics, unlike older all terrain cranes which used two engines. Simply said, one engine pulls the crane down the road and runs its hydraulic pump, while the other engine runs the upper part of the crane. This design of all terrain crane is still favored by older operators, because the newer all terrain cranes for sale have seal leaks, as they complain.
One of the most popular all terrain cranes for sale is probably the all terrain mobile crane. Yes, almost all all terrain cranes are mobile, as all cranes are meant to actually “move loads” from one place to another. However, some have increased mobility. Today, on the market can be found many different brands of all terrain mobile crane including Liebherr, Grove, Terex, Demag and Kato.

As many report, the Liebherr LTM 1750-9 is the best nine-axle all terrain mobile crane in the world. It has a lifting capacity of 750 tonnes and a specific telescopic boom designed for travel and work on construction sites. But this all terrain mobile crane was shadowed by another Liebherr crane, the LTM 11200-9.1. This all terrain mobile crane was the world’s largest in 2011. This crane is able to lift 1,200 tonnes and has an eight-part telescopic boom with a range of about 100 meters.
