‌L Type Single Beam Trolley Gantry Crane

Product Overview

L type single beam trolley gantry crane is a medium and light gantry crane with an electric trolley, which has the obvious features of "L" legs, making it easier for the crane to handle goods at a long distance.

It is ideal for outdoor applications where lifting facilities are provided without the cost of a building or any supporting steelwork.

L type single beam trolley gantry crane is the best choice for outdoor material processing.

It is widely used in cement plants, construction industry, electronics industry, warehouses, railways, food, papermaking, engineering and other industries.

But it is strictly forbidden to use it in dangerous environments such as high temperature, flammable, explosive, corrosive, etc.

Depending on your actual use, there are different gantry cranes for customers to choose from.

We have an experienced team of crane engineers.

We design the right gantry crane system for you, and provide a full range of after-sales services to enable your crane to operate quickly, stably and reliably.

• Overload protection device, overcurrent protection device, overvoltage protection device, track clamp, weight overload protection device, high-quality durable polyurethane material buffer, crane travel limit switch, low voltage protection function, emergency stop system, current overload protection system, etc.

Applications & Working Conditions

The ‌L Type Single Beam Trolley Gantry Crane is used across industrial plants, warehouses, steel mills, power stations, ports and logistics centers. It is available with optional lifting attachments such as lifting beams, electromagnets, grabs, C-hooks and coil tongs for special material handling.

Standard models operate in ambient temperatures from -20°C to +50°C. For special environments, we can supply explosion-proof electrics, high-temperature paint systems, dust-proof protection or corrosion-resistant coatings. Tell us your working condition and our engineers will confirm the correct configuration.

Customization Options

We customize span, lifting height, working class, control mode (pendant, wireless remote or cabin), and add frequency conversion speed control, explosion-proof protection or special coatings to suit your environment. Tell us your requirements and our engineers will prepare a tailored proposal.

Standard Supply Scope

Your order includes the complete crane structure, travelling mechanism, hoisting trolley or hoist, electrical control system, safety devices (limit switches, overload limiter, buffers, emergency stop), operation manual and inspection certificates. Optional extras include wireless remote control, frequency inverter, cabin with heater/air conditioner, lighting and special lifting attachments.

Quality Control & Testing

All structural welding is performed by certified welders and inspected before painting. Each crane undergoes no-load and full-load testing on our test bench, including brake test, limit switch verification and electrical safety check. Third-party inspection (SGS or buyer-nominated) is available before shipment.

Packing & Shipping

Cranes are shipped in knockdown form with steel structure, wheels, trolley, electrics and hardware carefully packed to prevent damage during ocean freight. Export packing follows our standard seaworthy specification, with wooden cases for electrics and control panels. Delivery options include FOB, CIF and DDP to your port.

Installation & After-Sales

We offer installation supervision and commissioning by our engineers, or fully turnkey installation by our experienced team. After commissioning we provide operator and maintenance training, a complete documentation package, and 24/7 spare parts and technical support for the lifetime of the crane.

What to Include in Your Inquiry

To receive an accurate quotation, please send us the following details with your inquiry: required lifting capacity (ton), span or working radius, lifting height, duty / working class, control method (pendant, radio remote or cabin), power supply voltage, site environment (indoor, outdoor, high temperature, dusty, explosion-proof area), and quantity. The more detail you provide, the faster our engineers can confirm the design and price.
