Industrial maintenance and bolting

Controlled bolting crews work far from any socket: wind turbines under construction, pipelines, refineries outside classified zones, pylons. Today, a small generator set powers a 1.5 kW hydraulic pump that only works two hours out of eight.

A single-phase 230 V electric pump (1.5 kW, 7 A) runs on the NV-P36, NV-W36 and NV-W50: about 3 h of actual tightening on the 3 kWh models, 5 h on the NV-W50, i.e. a full day of bolting.

Battery tools (36 V packs) recharge from any model: an NV-C24 recharges around a dozen packs, an NV-W50 nearly thirty. At height, the tools go up; the station stays at the bottom and recharges them.

Limits: no three-phase, and a pneumatic pump requires a compressor, which must be sized separately.

1.5 kW hydraulic pump at 60% average load (900 W): 2 h 54 on an NV-W36, 4 h 46 on an NV-W50.
