Description
The NR electric rope hoist represents the culmination of Weihua's extensive years of research and development, as well as its rich global market experience. It is a new-generation electric hoist that has been designed and manufactured in strict accordance with international standards such as ISO, GB, FEM, DIN, and BS. This hoist is capable of creating the utmost value for users through its outstanding durability, high-quality construction, and remarkable cost-effectiveness. It offers four distinct structural designs for users to select from, with a hoisting capacity spanning from 1 ton to 80 tons. The standard work duty is FEM 2M / ISO M5.
NR Electric Hoist Types/Models:
1. NRL (Low-Headroom Monorail Hoist)
2. NRS (Standard-Headroom Monorail Hoist)
3. NRT (Double-Rail Trolley or Crab)
4. NRF (Foot-Mounted Hoist)

Advantages
When purchasing a marine travel lift for sale, it is recommended to conduct a professional evaluation in the following four areas:
Energy-Efficient & Cost-Saving
Equipped with a high-efficiency permanent magnet motor meeting Grade 1 energy efficiency standards, the NR hoist achieves 30–40% energy savings and supports 0.1–3000rpm stepless speed regulation. Motor power is reduced by 30% compared to traditional hoists.
High-Precision & Intelligent Control
Advanced frequency conversion positioning technology enables millimeter-level inching and micro-speed operation for precise load handling. Smart features include zero-speed hover to prevent load slipping, electronic anti-sway, zone load limiting, and multi-hook synchronization for coordinated lifting.
Compact & Modular Design
The C-type structural layout with large-diameter drum minimizes left/right dead zones and maximizes lifting height. Modular design allows flexible configuration across 3–80t capacity with four structural types (standard, low-headroom, trolley-mounted, foot-mounted) to suit varied applications.
Maintenance-Free & Long Service Life
Hardened gear reducers are pre-filled with premium lubricants, requiring no replacement over the product lifecycle. Maintenance-free wire rope, electromagnetic disc brakes with automatic clearance compensation, and nylon rope guides (wear-resistant, no
