Wacker
Rammers — BS 50-4s and BS 60-4s
Key innovation: First 4-cycle rammer with low-oil shutoff
Wacker is the first manufacturer to offer a 4-cycle rammer with low-oil shutoff, the company says.

Wacker
Portable generators: GP 3800A, GP 5600A, GPS 5600A, GP 6600A, GPS 6600A
Key innovation: GFCI system for all receptacles
Wacker's premium portable generator series features a central ground fault interrupter (GFCI) system for all receptacles, including 120-volt and 240-volt twistlocks. The new GFCI sensor offers personal protection to operators no matter which receptacle is being used by monitoring all outlets for current leakage. It trips the main circuit breaker in the event of a current leakage. This system is designed to improve durability and reliability because the GFCI sensor only monitors current, eliminating the possibility of damage from over-current. If a current leakage is detected, the GFCI triggers the main circuit breaker, which is rated to handle the total current output of the entire generator and can withstand current surges and repeated tripping without a problem. Conventional GFI-protected generators use small auxiliary breakers built into each 120-volt duplex receptacles, which can be damaged by over-current or repeated tripping, and are a frequent maintenance item on rental generators.
