Low Headroom Overhead Crane Manufacturer

Product Description

Low-headroom bridge cranes are specifically designed for factories, plants, and warehouses with limited ceiling height. By reducing the height of the hoisting mechanism, they maximize vertical space utilization, enhance operational efficiency, expand available storage capacity, and minimize costly structural modifications. Compared to standard single-girder cranes, the overall height is typically reduced by 0.3 to 0.5 meters.

Nucleon Crane offers various types of low-headroom bridge cranes and customized design solutions to meet your lifting requirements. Contact us today for a tailored lifting solution.

Types of Low-Headroom Bridge Cranes

Low-headroom bridge cranes are categorized into two main types based on main girder structure and rail support methods.

Single-girder low-headroom crane

Utilizes a single I-beam or box girder as the main girder, featuring a lightweight structure and economical cost. Suitable for light to medium-duty operations ranging from 1 to 20 tons, with moderate spans, in workshops, warehouses, and production lines.

Double-girder low-headroom overhead crane

Double-girder low-headroom cranes

Constructed with two box-type main girders, these offer high structural rigidity and stability. Designed specifically for medium-to-heavy loads and large spans, they can handle capacities up to 500 tons and are commonly found in heavy industries such as machinery manufacturing and metallurgy.

Underslung overhead cranes

Based on track support methods, they are further categorized into underslung overhead cranes, where the main girder is suspended from tracks beneath the factory roof trusses, providing flexible spatial solutions.

Parts

Low-headroom bridge cranes are compact lifting devices that optimize pulley arrangements to enable hooks to operate closer to the ceiling, effectively maximizing vertical space utilization in industrial facilities. Their primary components include:

Main and End Beams: Form the primary load-bearing structure of the crane, traveling longitudinally along the rails.
Hoist Trolley: Moves horizontally along the main girder rails, integrating the hoisting mechanism (including motor and wire rope drum), low-headroom pulley block, and hook.
Power and Control System: Includes drive motors, brakes, electrical cabinets, and ground controllers or operator cabs.
Safety Devices: Such as limit switches and overload limiters, ensuring operational safety.

Features

High Space Utilization: Unique low-headroom design allows the hook to reach its maximum position flush against the main beam, effectively increasing lifting height.
Compact and Lightweight Structure: Optimized trolley and end beam design reduces self-weight, lowering requirements for factory foundation load-bearing capacity.
Smooth and Efficient Operation: Typically equipped with variable frequency speed control and precision control systems for smooth starts/stops and accurate positioning.
Modular Design: Core components are standardized and modularized, facilitating selection, configuration, installation, maintenance, and future upgrades.
High Safety and Reliability: Built-in overload limiters, multiple limit switches, and high-grade braking systems ensure safe operation.

Applications

Low-Ceiling Factory Retrofits: Ideal for existing facilities with height restrictions, delivering optimal space solutions.
Production Line Material Handling: Suitable for machining, assembly lines, and other processes requiring frequent, precise lifting operations.
Warehouse Logistics & Storage: Used for material handling, stacking, and loading/unloading within warehouses, maximizing storage space utilization.
Equipment Maintenance & Installation: Designed for confined maintenance spaces, providing lifting support for large equipment servicing and installation.
Specific Industrial Sectors: Widely applied in automotive manufacturing, metal processing, light industry electronics, and other sectors demanding spatial efficiency and precision.
