LX Type Electric Single-Girder Suspension Crane
The LX Type Electric Single-Girder Suspension Crane (LX monorail crane) is a light-duty rail-mounted lifting device designed for use with CD1/MD1 electric hoists. With a lifting capacity of 0.5 to 10 tons and a span of 2 to 22.5 meters, it is ideal for facilities where the clearance from the crane rail to the bottom chord of the roof truss is ≤500mm. This article provides a detailed overview of the LX Type suspension crane, covering technical parameters, model specifications, dimensional drawings, pricing, and a buying guide.
The LX Type Electric Single-Girder Suspension Crane operates in conjunction with CD1 and MD1 electric hoists, functioning as a light-duty, rail-mounted crane. It is designed for use in factories and warehouses where the clearance from the building rail to the bottom chord of the roof truss is ≤500mm. This unit is floor-operated. The working environment temperature ranges from 25°C to 40°C. Operation in flammable, explosive, or corrosive atmospheres is strictly prohibited.
LX Type Electric Suspension Crane Design Standard
The LX Type Electric Single-Girder Suspension Crane is a commonly used electric suspension crane, also referred to as a single-girder suspension crane, suspension single-girder crane, electric suspension crane, or simply suspension crane. It is manufactured in accordance with the national standard JB/T2603-2008 "Electric Suspension Cranes" (superseding the older standards JB/T2603-1984 and JB/T2603-1994).
The LX Type Electric Single-Girder Suspension Crane is designed to work with CD1/MD1 wire rope hoists or electric chain hoists. The crane bridge wheels travel along the bottom flange of an I-beam, making it a light-duty, rail-mounted suspension crane.
Features of the LX Type Electric Single-Girder Suspension Crane
The electric single-girder suspension crane features a compact design that minimizes the footprint within the workshop. It is particularly well-suited for workshops that lack the corbels required for traditional overhead cranes and is typically installed on the roof structure of flat-roof workshops or steel structure workshops with load-bearing ring beams. The LX Type Electric Single-Girder Suspension Crane is slightly more cost-effective than the LD Type Electric Single-Girder Crane and is widely used in applications with intermittent duty cycles, such as water treatment plants, sewage treatment plants, pump rooms, machining and assembly workshops, industrial and mining enterprises, pharmaceutical factories, and warehouses.
The LX Type Electric Single-Girder Suspension Crane offers two operating modes: floor operation via a wired pendant or wireless remote control (both options can be provided). The crane service rating for this single-girder suspension crane is A3/M3.
The electric suspension crane is designed for a working environment temperature range of -25°C to 45°C, with a relative humidity of ≤85%. It is suitable for use in environments free from flammable, explosive, and corrosive media. For special environments, explosion-proof suspension cranes can be customized. For applications involving molten metal or highly toxic substances, metallurgical suspension cranes can be manufactured to order.
Standard power supply: AC 380V 50HZ. Custom power supply options are available upon request.
The LX Type Electric Single-Girder Suspension Crane consists of the crane main girder, suspension end carriages, electric hoist, and DK electrical cabinet. The power supply system is available in two configurations: conductor rail (busbar) and flexible trailing cable.
Environments containing flammable or explosive media are not suitable for the standard LX Type Electric Single-Girder Suspension Crane. In such cases, the LXB explosion-proof suspension crane should be selected. The power supply system for explosion-proof electric suspension cranes must utilize a flexible trailing cable instead of a conductor rail to prevent sparks from the electrical system that could cause a fire or explosion. This is a critical safety requirement.
Application Scenarios and Customer Cases
The core advantages of the LX Type suspension crane lie in its "no corbel requirement, low cost, and suitability for flat-roof workshops." It is particularly well-suited for the following scenarios:
▎Water Treatment Plants / Sewage Treatment Plants
Pump rooms, filter workshops, and chemical dosing rooms in water treatment plants typically have low ceiling heights, with the clearance from the bottom chord of the roof truss to the rail often less than 500mm, making it impossible to install traditional LD Type single-girder cranes. The LX Type suspension crane mounts directly onto the roof I-beam, eliminating the need for corbel supports and minimizing structural modifications to the building. For a county-level water plant in Xinxiang, Henan, where the pump room had a clear height of only 4.2 meters, we supplied a 2-ton LX Type crane with an 8-meter span, installed above the filter tanks in the chemical dosing room. Paired with a CD1 electric hoist, it handles daily tasks such as lifting sluice gates and chemical bags with ease, at a total cost of under CNY 30,000.
▎Machining and Assembly Workshops
Machining workshops are characterized by dense equipment layouts and frequent but not heavy-duty lifting operations. The A3/M3 service rating of the LX Type crane is perfectly matched to this type of duty cycle—typically dozens of lifts per day, handling workpieces of 2 to 5 tons each. A precision casting facility in Changzhou installed three LX Type 5-ton suspension cranes in its investment casting workshop, covering the shell-building, pouring, and finishing areas. Customer feedback highlighted two key benefits: first, the flexibility of the circular rail layout, allowing the three cranes to cover the entire diagonal of the workshop; second, the speed of installation—only 12 days from order placement to commissioning.
▎Pharmaceutical Factories / Warehouses
Raw material and finished goods warehouses in pharmaceutical plants have low lifting frequencies but require clean equipment with no risk of oil leakage. The LX Type crane, with its electric hoist and conductor rail power supply, offers a cleaner and more reliable solution than older cable-reel systems, eliminating the problem of cable dragging and wear on the floor. A traditional Chinese medicine processing plant in Anhui installed a 3-ton LX Type crane with a 12-meter span in its raw material warehouse for handling herbal medicine bales. After installation, warehouse space utilization increased by 30%—because the suspended design takes up no floor space, shelving can be placed right up against the walls.
▎Factory Retrofits / Temporary Lifting Points
In older factory retrofit projects, a common challenge is "the original building wasn't designed for a crane, but now one is needed." The LX Type suspension crane is the preferred solution for such retrofits—no need to break out corbels or pour new crane runway beams; it simply mounts directly onto the existing roof I-beam. We completed a retrofit for an old foundry workshop of a machinery factory in Zhengzhou. Previously, molds were moved manually; after installing an LX Type 3-ton suspension crane, handling time was reduced from 40 minutes to 8 minutes, with no structural modifications to the building required.

Why Choose Kelude Heavy Industry
The LX Type suspension crane has a simple structure, but there are many nuances in its installation and selection. Kelude Heavy Industry has solid experience in this field:
- No Compromise on Selection: The matching of lifting capacity, span, and hoist model directly impacts performance. We've seen cases where customers bought a hoist separately to pair with an LX main girder, only to find the travel wheel didn't align with the I-Beam flange width, resulting in rework. Our solution is a fully matched four-piece set – main girder, end carriage, hoist, and electrical control system – all test-run before leaving the factory.
- Proven Installation Expertise: The key to LX Type installation lies in the load-bearing calculation of the suspension system and the leveling of the I-Beam Rail. Different factory building structures (precast slab roof trusses, steel structure roof trusses, concrete beams) require different suspension methods. When developing an installation plan, we send personnel to inspect the roof truss structure on-site before finalizing the approach – we don't rely on a "one-size-fits-all" drawing.
- Transparent Pricing: Standard specifications (0.5~10 tons, spans 3~16 meters) are clearly priced with no hidden fees. Custom non-standard spans and special lifting heights are quoted based on the revised material list, with no additional management fees.
If you have an existing factory building where you'd like to add a crane, or if you're unsure whether your roof truss can support an LX Type, send us photos of the site along with the span dimensions, and we'll help you assess the feasibility. Free evaluation – no charge unless we deliver a solution.
FAQ
Q: What's the difference between an LX Type suspension crane and an LD Type single girder crane?
A: The LX Type is a suspension crane – the main girder runs on the factory's I-Beam Rail via a suspension system, requiring no corbels or runway beams. The LD Type is a supported crane – the main girder runs on rails at both ends and requires corbels for support. The LX Type is ideal for flat-roof factory buildings without corbels and is also more cost-effective.
Q: What is the maximum lifting capacity for a suspension crane?
A: Standard LX Type electric single-girder suspension cranes have a lifting capacity of 0.5~10 tons with spans from 2~22.5 meters. Custom non-standard manufacturing is available for special requirements, but due to the limitations of the factory's load-bearing beam structure, we recommend switching to the LD Type or LH Type for capacities exceeding 10 tons.
Q: How much does an electric suspension crane cost?
A: The price depends on the lifting capacity and span. A 1-ton crane with a 3-meter span costs approximately 10,000~20,000 RMB; a 3-ton crane with a 6-meter span costs approximately 20,000~40,000 RMB; a 5-ton crane with a 10-meter span costs approximately 40,000~70,000 RMB. Prices include transportation and Installation & Commissioning. For a detailed quotation, please provide parameters such as lifting capacity, span, and lifting height.
