KEY DEALER FEATURES

All-Steel "Nitchi-Matic" Construction Unlike modern hoists that use aluminum castings, the Nitchi MH-5 series features a frame made of two rugged steel side plates. This ensures maximum protection against dynamic shock loads and eliminates the risk of housing cracks under extreme industrial stress.

Dual Braking System for Maximum Safety This unit utilizes a redundant braking system featuring an electromagnetic brake and a mechanical load brake. This combination ensures positive load spotting and prevents any "drifting" of the 10,000 lb load, even during power interruptions.

Fuji High-Performance Motor The integrated Fuji Brake Induction Motor is world-renowned for its durability and rapid braking response. With a 30-minute rating and Class B insulation, it is built to withstand frequent use over long production shifts without overheating.

Precision Helical Gearing The first-stage helical gear reduction operates in a continuous oil bath. This design reduces gear tooth impact and vibration, resulting in a significantly quieter operation and a longer drivetrain lifespan compared to standard spur-geared hoists.

Ultra-Tough Case-Hardened Load Chain Nitchi's proprietary alloy steel load chain features a carbonized hard surface that resists erosion and wear several times longer than conventional through-hardened chains, while the soft core maintains the elasticity essential for safe material lifting.
