The HR21 Hybrid AWD also incorporates Niftylift's new ToughCage technology. Its tough impact resistant composite base and larger cross-section steel cage give extra strength and durability, both protecting the operator and reducing the risk of damage to the cage. As well as resisting damage the new ToughCage absorbs much of the force of an impact preventing damage to the boom. Should damage occur the rails can be replaced separately for a fast low cost repair.
