The Height Rider 15 4-wheel-drive (HR15 4x4) offers one of the most impressive working envelopes in its class. Its compact base allows it to manoeuvre easily in enclosed spaces and its extremely low overall weight helps to minimise transportation costs. The HR15 4x4's 1.8m wide ToughCage offers more space for materials and tools and a 150° fly-boom with 180° cage rotation increases accuracy when positioning the cage. The tough, impact-resistant composite base and larger cross-section steel rails of the ToughCage give strength and durability, while the multi award winning SiOPS® provides additional operator protection. This Hybrid machine incorporates a power-optimised TIER IV compliant engine supported by the machine's battery pack for when extra power is needed. This maintains power and performance while reducing fuel consumption for maximum efficiency. The Innovative 'Diesel Re-Gen' feature also recharges the batteries without a mains power source, giving a 'fast-charge' whenever the machine is idle and the engine running. In addition, an electric-only mode allows zero-emission operation, making it ideal for indoor use, or for quiet, clean operation.
