Hoist Winch

Basic Parameters

Rated Pull Force

10 kN – 5000 kN (1 – 500 t)

Light-duty ≤ 50 kN, Medium-duty 50 – 300 kN, Heavy-duty > 300 kN.

Rated Speed (Wire Rope / Chain)

0.1 – 10 m/min (Electric); 0.05 – 5 m/min (Hydraulic)

Stepless speed regulation available via VFD or hydraulic valve.

Drum Specification (Diameter × Length)

Diameter: 80 – 1500 mm; Length: 300 – 5000 mm

Drum diameter ≥ 16 × wire rope diameter (GB/T 10055 standard).

Rope Capacity

5 – 1000 m

Customized according to working height / traction distance; multi-layer winding drum available.

Work Duty Class

M1 – M8 (GB/T 3811-2008)

Light-duty scenarios M1 – M3, heavy-duty industrial scenarios M4 – M8.

Power System Parameters

Motor Power (Electric Winch)

0.55 – 1000 kW

Higher rated pull force requires higher power (e.g., 10 t winch equipped with 15 – 22 kW motor).

Hydraulic System Pressure (Hydraulic Winch)

10 – 35 MPa

Hydraulic motor displacement 10 – 200 mL/r.

Power Supply Specification (Electric Winch)

AC 380 V / 400 V / 660 V (Three-Phase), 50 / 60 Hz

Special scenarios customizable to 220 V single-phase or DC power supply.

Transmission & Braking Parameters

Transmission Ratio

10 – 1000 (Multi-stage reducer)

Planetary reducer transmission ratio more precise (error ≤ ±0.5%).

Braking Method

Electromagnetic normally-closed brake, Hydraulic disc brake, Band brake

Braking torque ≥ 1.5 times rated load torque, ensuring safe stopping.

Braking Response Time

≤ 0.3 s (Electric); ≤ 0.5 s (Hydraulic)

Rapid braking after power-off / shutdown to prevent load slipping.

Structural Parameters

Overall Weight

50 kg – 50000 kg

Light-duty ≤ 500 kg, heavy-duty up to 50 t or more (including base).

Installation Dimensions (L × W × H)

500 × 300 × 400 mm – 5000 × 3000 × 4000 mm

Fixed type dimensions are larger; mobile type is more compact.

Wire Rope Specification

Diameter: 6 – 60 mm, Strength Grade: 1550 – 1960 MPa

Material: galvanized steel wire rope or stainless steel wire rope, wear-resistant and corrosion-resistant.

Safety & Environmental Parameters

Overload Protection

Alarm at 10% – 20% overload; shutdown at 25% overload.

Equipped with tension sensor or torque limiter.

Limit Protection

Upper / lower limit switches (mechanical + electronic dual protection).

Prevents overwinding of drum causing wire rope breakage.

Protection Class

IP44 – IP65

Select IP54 or above for outdoor / dusty environments; IP65 for humid environments.

Operating Temperature Range

-40 ℃ – +60 ℃ (Standard); -50 ℃ – +80 ℃ (Special Type).

Cooling system required for high-temperature scenarios; special lubricating oil needed for low temperatures.

Noise Level

≤ 75 dB (measured at 1 m distance).

Higher gear precision results in lower noise (precision transmission ≤ 65 dB).

Applicable Standards

Product Standards

GB/T 10055-2023 "Safety Regulations for Lifting Appliances", GB/T 14405-2011 "General Purpose Bridge Cranes".

Complies with national lifting equipment safety standards; some models comply with ISO 4301.
