It's designed to bG used in the harshest environments and features active pothole protection for an increased ground clearance, preferred in the contracting environment.

Tallor-made to t11e operator's and contractor's needs in the building Industry. the LEONARDO range of platforms eliminates the need for scaffolding. scissor 111\s and normal push-around units. No more ladders, no outriggers. no !lassies. One man can easily do a job safely. quickly and elffclenlly.

PORTABLE Wnh Leonardo HO, the user c;an travel all over the site with ease-through doorways. up access ramps and Into fight spaces-thanks to the extremely compact slze of lhls ptalform and 35% gradeabillty. Weighting only 508 Kg (1119 Lbs), Ills e<>mpact and light enough to enter most elevators to reach the top Ooors of high bulldlngs in no time at all. Drivable through standard doorways, without the operator leaving the platform.

SAFE Dnveable at its full4.9 mt (9.6') wol'l<.ing height with the maximum load and the platform completely extended at an automatic slow speed. No more exhausting mounUng on and off the platform or scaffold to push it into the right position! Unrestricted capacity 180 Kg (397 Lbs) reduce the need to climb up or down to load material. Built-in tilt sensor, flashing light, audible alarm and active pot-hole protection are all standard features

DURABLE Simple, trouble-free and cost effecUve, the Leonardo range of products Is the result of 1 5 years technical improvement. Maintenance-free lifting mast. carefully selected components and extremely simple desfgn make for low cost servicing: other than controlling the water level in the batteries, all our Leonardo models are virtually maintenance-free.
