Single Girder Overhead Crane for Foundry and Metal Processing Plants

A single girder overhead crane is an economical and efficient lifting solution designed for light and medium-duty material handling applications. With a lifting capacity ranging from 1 ton to 20 tons, it is widely used in workshops, warehouses, production facilities, and maintenance areas. Common capacities include 1 ton, 2 ton, 3 ton, 5 ton, 10 ton, 15 ton, and 20 ton models. The crane is manufactured according to international standards such as DIN, FEM, and ISO, ensuring reliable performance, safety, and long service life.

SEVENCRANE is a professional manufacturer specializing in the design and production of high-quality lifting equipment. We provide a wide range of crane solutions, including single girder overhead cranes, double girder cranes, gantry cranes, jib cranes, and electric hoists, along with related components such as winches, lifting accessories, remote control systems, and end carriages.

Our single girder overhead cranes feature a compact structure, easy installation, smooth operation, and low maintenance requirements. They are suitable for various industries, including manufacturing, logistics, machinery processing, steel fabrication, and general industrial applications.

With extensive manufacturing experience and strict quality control, SEVENCRANE delivers safe, reliable, and cost-effective lifting solutions for customers worldwide. We also provide customized designs, technical support, installation guidance, and after-sales service to ensure each crane meets the specific requirements of different working environments.

1. Overload Limit Switch

The overload limit switch is designed to prevent the crane from lifting loads beyond its rated capacity. When an excessive load is detected, the system automatically stops the lifting operation, protecting the hoisting mechanism, crane structure, and other components from damage caused by overloading.

2. Rubber Buffers

Rubber buffers are installed at the ends of the crane bridge and trolley travel paths. They help absorb impact energy when the crane reaches the end position, reducing vibration and collision forces. This improves operational safety and extends the service life of the crane structure and traveling components.

3. Electric Protective Devices

The electrical system of the single beam overhead crane is equipped with multiple protection functions, including short-circuit protection, phase failure protection, and electrical insulation protection. These devices help ensure stable operation and prevent electrical failures during daily use.

4. Emergency Stop System

An emergency stop button allows operators to quickly shut down crane operation in case of unexpected situations. This safety feature provides immediate control during emergencies, helping prevent accidents and protect both personnel and equipment.

5. Voltage Lower Protection Function

The voltage protection system monitors the power supply condition during crane operation. If the voltage drops below the safe operating range, the system will stop the crane automatically to avoid motor damage, unstable operation, or potential safety risks.

6. Current Overload Protection System

The current overload protection device monitors the electrical current of the crane motors. When abnormal current levels occur due to mechanical problems or excessive loads, the system will disconnect the power supply to protect the motor and electrical components.

7. Rail Anchoring Device

Rail anchoring devices help secure the crane runway system and prevent unwanted movement caused by external forces, vibration, or accidental impacts. They improve the stability and reliability of the crane during operation.

8. Lifting Height Limit Device

The lifting height limit device prevents the hook or lifting equipment from moving beyond the maximum safe lifting position. It automatically stops the hoisting mechanism when the upper limit is reached, avoiding damage to the hoist system and ensuring safer lifting operations.
