dvojnosníkový portálový žeriav

V moderných skladových a logistických prevádzkach, efficient material handling is the core of improving operational efficiency, reducing labor costs, and ensuring safety. As a versatile and reliable lifting equipment, gantry crane for warehouse use has become an indispensable part of large and medium-sized warehouses, distribučné centrá, a logistických uzlov. Unlike overhead bridge cranes that rely on the building’s structural support, gantry cranes feature a freestanding portal structure, which allows them to operate flexibly without the need for ceiling reinforcement or permanent runway beams, making them suitable for various warehouse layouts and operational needs.

The primary function of a gantry crane for warehouse use is to lift, pohybovať sa, and stack heavy loads such as pallets, prepravky, časti strojov, surovín, and finished goods. It effectively solves the pain points of manual handling and forklift limitations in heavy load transportation, especially in scenarios where loads are too heavy, spans are too large, or workstations need to be adjusted flexibly. By optimizing the material handling process, gantry cranes not only improve the speed and accuracy of loading, vykládka, and storage but also reduce the risk of goods damage and workplace accidents, laying a solid foundation for the standardized and efficient operation of warehouses.

There are various types of gantry cranes for warehouse use, each designed to adapt to different warehouse sizes, požiadavky na zaťaženie, and operational scenarios. Below is a detailed introduction to the main types, including their brief introduction, core parameters, and characteristics.

1. Single-Girder Gantry Crane

Brief Introduction

As the most common type of gantry crane in small and medium-sized warehouses, the single-girder gantry crane has a simple structure with one main beam supported by two legs. It is mainly used for light to medium load handling and is ideal for scenarios requiring frequent, simple lifting tasks.
