The Terex RT 100US is a rough terrain crane with a rated capacity of 100 US tons.


The model comes in a Terex branded box sleeve which encloses expanded polystyrene trays.

The review model had no defects or missing parts.

There is an instruction sheet for the model which is pictorial and it has a list of parts, but there are no reeving diagrams.


The carrier chassis has the drive transmission modelled in plastic.  The plastic wheels look good and the large rough terrain tyres have a chunky tread pattern. 

The carrier has painted lights front and rear, and there is very little plastic used.  There are access stairs at the front, silvered metal ladders and metal tanks and boxes.  The engine cover is simple with some texturing, and the exhaust arrangement looks very good with an etched box. There is an attachment point for the hook blocks during transport.

The outriggers are tough plastic and are two stage with an excellent colour match.  They are simple with chevron graphics applied. The outrigger pistons are smooth when extended, and they have plastic pads.

The crane cab has plastic grab rails and a mirror with a reasonably detailed interior.  There are some tiny graphics on the door. 

The crane body is simple with two winches.  The one-piece counterweight block has sharp graphics.

The large main boom ram has a plastic jacket with an excellent colour match.  The boom has a small spooling drum detailed.  There are metal sheaves in the boom head.  A plastic rooster extension is included.

The bi-fold swingaway jib is a very nice metal lattice casting with a plastic solid section which has an excellent colour match. All sheaves are metal.

The hook block has five sheaves and a single line hook is also included.


The axles steer and the range of movement is very good.  The rear axle has some oscillation. 

Access stair handrails at the front can be raised or lowered to accommodate the counterweight being placed on the deck.

The outriggers are fully functional with extending beams and pistons that screw down with smooth pistons.  Plastic pads clip on securely.  The outriggers are strong enough to support the crane wheels-free.

The crane cab tilts and can hold any pose.

The counterweight is detachable.

The boom is raised using the very large ram which has a locking mechanism which is tightened using a supplied key.  It works well when fully tightened and it will hold the boom as desired as long as it is tightened enough. 

The telescopic sections extend smoothly and lock into place when full extension is reached. 

A rooster line extension can be added or left off.

The winch drums can only be turned by finger on the drum.  There is enough friction on the drums to hold most loads, and there is also a positive brake mechanism.

The fly jib can be installed and run at half or full length.  It can be pinned to set offset angles.


This a robust model with a high metal content.

The paintwork is very good as are the few graphics.


It is fully priced.


This is a strong model with nicely engineered functionality.  It looks just a little plain in the Terex colour scheme.


The model first appeared at the ConExpo Exhibition 2017. It also appeared as the European version RT 90 with model number #2115.
