Product description

Reliability with 90 Tonnes of Capacity

If it’s not broken, don’t fix it! The GR-900EX-4, powered by a Cummins engine, was fully redesigned (not fixed, but redesigned) in 2020 and looks ahead with confidence, boasting its 90.7t of capacity. The new GR-900EX-4 kept the same boom and jib specs as its predecessor, making for a smooth transition. In a world first, this crane has a new Smart Counterweight setup which allows the crane to place the counterweight in two positions which will now boost the radius of the crane substantially.
