Price of Single Girder Gantry Crane for Open Yard

♦Product Introduction

Single girder gantry cranes are widely used in workshops, warehouses, open yards, and windy outdoor environments where overhead crane runways are not practical. They are typically used together with an electric hoist to perform lifting and material handling operations with efficiency and safety. With a lifting capacity ranging from 2 tons to 20 tons and spans of 10m to 30m, these cranes are suitable for diverse industrial applications. They are designed to operate in environments up to 40°C, with a working duty of up to 25% and wind pressure not exceeding 125Pa. Operation modes can be ground control or remote control, depending on site requirements.

♦Technical Features

The drive system adopts an advanced three-in-one transmission, ensuring smooth and reliable crane movement. The electrical system uses a contactless module with variable frequency control, allowing micro-speed and dual-speed functions for precise positioning and stable inching performance. Standard safety features include overload protection, skew detection, anti-lifting hook protection, and overcurrent protection. The control system typically operates at a safe low voltage (12V for the pendant handle), while the overall electrical components are designed for long service life and high reliability.

♦Selection Principles

When selecting a single girder gantry crane, key considerations include the industry of application, lifting frequency, number of starts per hour, and daily working hours. It is important to remember that single girder gantry cranes are designed as light to medium-duty lifting equipment. For light-duty use, the typical number of starts ranges from 10–80 times per hour, while for medium-duty it ranges from 15–40 times per hour. In harsher environments or higher operating temperatures, the duty cycle should be reduced accordingly to ensure safe and reliable performance.

♦Precautions

Operators must ensure that the crane is securely locked when not in operation. It is strictly forbidden to lift molten metals, flammable or explosive materials, corrosive substances, or overloads beyond rated capacity. When operating with loads outside the supporting legs (cantilever operation), the permissible load must be reduced by 10–20%, and the external suspension length should not exceed one-third of the crane span. For smaller spans, cantilever operation should be avoided. All lifting operations must be performed with the load kept as close as possible to the support legs to ensure stability and safety.

Outdoor Storage Yards: Single girder gantry cranes are widely used in open-air storage facilities for loading and unloading bulk goods, steel sections, containers, and raw materials. Their ability to operate without overhead structures makes them ideal for maximizing outdoor space utilization.

Workshops and Factories: In industrial workshops and manufacturing plants, these cranes streamline material handling processes. They move raw materials to production areas and transfer finished products to storage zones, reducing manual handling and improving efficiency.

Assembly Lines: Their precise and controlled lifting capabilities make them an excellent fit for assembly operations. Whether positioning machinery parts, vehicle components, or large equipment, single girder gantry cranes ensure accuracy and consistency during the production process.

Maintenance and Repair: These cranes are valuable tools for lifting engines, turbines, pumps, and heavy machinery during inspection, servicing, or repair. Their flexibility allows maintenance teams to reduce downtime and complete tasks more safely and efficiently.

Construction Sites: Single girder gantry cranes are often deployed on construction projects to transport steel beams, precast concrete elements, and other building materials. Their adaptability makes them suitable for changing site layouts and evolving project requirements.

Logistics and Warehousing: In logistics hubs and warehouses, they handle pallets, packaged goods, and containers. This improves the speed of loading, unloading, and internal distribution, supporting just-in-time operations.

Shipyards and Ports: These cranes assist in handling smaller vessels, ship components, and marine equipment. They complement larger lifting systems by offering flexibility for lighter, more precise lifting tasks.

Energy and Power Plants: Single girder gantry cranes are also employed in power generation facilities for moving heavy transformers, generators, and maintenance equipment, ensuring safe and efficient handling of critical components.
