Winner of the International Powered Access Federation's 'IAPA Product of the Year 2018' award, the HeightRider 21 4x4 (HR21 4x4) self-propelled cherry picker will lift 2 persons and their tools to a working height of 20.8m or a working outreach of 13m.

Proportional controls deliver smooth, measured operation while 160º cage rotation and a 150º fly-boom allow precise positioning anywhere in its vast working envelope.

Weighing just 6,640kg, the HR21 4x4 combines innovative weight and space-saving design with an excellent turning circle to deliver outstanding manoeuvrability on-site and lower transportation costs.

The HR21 4x4's 1.8m wide ToughCage (steel cage option available) offers more space for materials and tools and the tough, impact-resistant composite base and larger cross-section steel rails of the ToughCage also give additional strength and durability, while the multi-award-winning SiOPS® provides additional operator protection.

The HR21 4x4 is available with two power options, Diesel-only or Hybrid power:

The Diesel-only option incorporates a versatile and efficient Tier 4 Final/Euro Stage V compliant engine to deliver maximum traction and gradeability, making it ideal for rough or uneven ground.

The Hybrid option incorporates a smaller, power-optimised Tier 4 Final/Euro Stage V 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.
