Environment-friendly cranes

The EC400 (16,000 ft.-lb.-rated; 4000-lb. lifting capacity) and EC500 (25,000 ft.-lb.-rated; 5000-lb. lifting capacity) cranes feature a "piggy-back" or double-boom design that provides more strength than traditional square boom designs. They also use a nontoxic, noncarcinogenic hydraulic oil that's recyclable and biodegradable. The EC400 has manual boom reach options of 16 or 20 ft., and the EC500 manual boom reach is 20 ft. Both fit comfortably behind the profile of most chassis cabs. Stellar Industries Inc. 800-321-3741. www.stellarindustries.com
