single girder grab overhead crane

LD Type Single Girder Grab Overhead Crane

A single-girder grab overhead crane is a type of lifting equipment consisting of a single main girder bridge structure. It is typically suitable for grabbing bulk materials in small to medium-sized tonnage and medium-span applications. It features a simple overall structure, low cost, and ease of operation. It can be equipped with either a Double Flap Grab Bucket or a Multi Flap Grab Bucket to suit different operating conditions. Single-girder grab overhead cranes typically have a load capacity of 2-5 tons.

double beam grab overhead crane

Double Beam Grab Bridge Crane

The Double-beam grab bridge crane is heavy-duty lifting equipment. They are primarily suitable for large-span, high-tonnage, and high-frequency applications, handling, transporting, and stacking bulk materials. With a duty class up to A6, they are widely used in heavy industries such as metallurgy, ports, power generation, and building materials. Typically, a Double-beam grab bridge crane has a load capacity of up to 32 tons.

Structure And Components

  • Main beam: It is composed of two high-strength steel beams. The double beams are connected to form a stable frame structure. This structure provides strong bearing capacity and torsion resistance.
  • End beam: It connects the two ends of the main beam to form a closed bridge structure. This structure enhances the overall stability of the crane.
  • Grab: It is the core component of QZ grab overhead crane. It can grab bulk materials such as ore, coal, sand and gravel. There are four flap grab bucket and double flap grab bucket. Clients can select one based on material characteristics.
  • Trolley: It is the operating mechanism that carries the grab. It can move freely on the main beam to realize the horizontal transportation of materials.
  • Trolley operating mechanism: It includes the drive motor, reducer and wheel group. It realizes the longitudinal movement of the crane along the track.
  • Electrical system: It includes control cabinet, cables, limit switches, etc. It is responsible for the power supply and operation control of the crane.

Different Types of Overhead Cranes: A Complete Guide

What You Need to Know Before You Choose Choosing the wrong overhead crane creates problems that show up long after installation — in downtime, maintenance costs, and operational limitations. Overhead cranes are among the most widely used lifting systems in industrial facilities worldwide. They mount horizontally above the working area and move heavy loads accurately from point A to point B across the full floor coverage of a bay. But the different types of overhead cranes serve genuinely different purposes. A unit designed for a light-duty repair workshop is not the same machine as one built for a steel mill running three shifts. This guide covers what each type is, where it works best, what it’s made of, and what it typically costs — based entirely on the actual product range available from Voitto Crane. What Is an Overhead Crane? An overhead crane is a lifting system mounted horizontally above a workshop, production line, or warehouse. It moves heavy objects stably and precisely across the full working area below. The structure consists of one or two main girders, two end…
