Telescopic boom lifts typically have a reach of between 40 and 185 feet. However, the tallest boom lift in the world, the Snorkel 2100SJ, can reach 210 feet. Keep in mind reach distances may be different vertically than horizontally – and even in terms of range of motion. Check the specifications before you rent any model. For example, one model may reach to a certain height vertically, but it would be unsafe to extend that same reach horizontally. This may affect your decision based on the kind of work you need it to do.
