All crane column casings are applied<br />

with a pearl structure coating for longlasting<br />

UV protection.<br />

Qualities of synthetic casings<br />

at a glance:<br />

- Optimal light-weight construction<br />

- Ergonomic shapes<br />

- High resistance to temperature<br />

and UV rays<br />

- Premium appearance and surface feel<br />

- Impact-resistant, sturdy and robust<br />

Job-oriented stress tests confirm<br />

the durability of synthetic<br />

casings.<br />

The process: In R-RIM (Reinforced reaction<br />

injection molding) two components<br />

(polyol and isocyanate) and a flexibilizer<br />

are mixed in a so-called mix head to<br />

increase impact resistance and injected<br />

under high pressure into a molding<br />

tool. The exothermic reaction of the<br />

components produces the thermoset<br />

plastic polyurethane, which can then be<br />

removed from the tool.<br />

Treads designed to be both functional<br />

and highly resistant are produced with<br />

the aid of a polyamide plastic reinforced<br />

with fiber glass. These components<br />

are formed using the well-established<br />

injection molding process.<br />
