Single Girder Crane Price Q&A: 1-20 Ton Models, Specs & Selection
Key Point A single-girder crane (LD Type) typically costs approximately $4,400–$8,900 for 1 ton, $5,900–$11,800 for 2 tons, $7,400–$14,800 for 3 tons, $8,900–$17,700 for 5 tons, $14,800–$29,500 for 10 tons, $23,600–$44,300 for 16 tons, and $29,500–$59,000 for 20 tons. Pricing varies with span, lifting height, and hoist configuration. This article provides reference quotations and selection guidance by capacity tier.
The single-girder crane (LD Type electric single-girder bridge crane) is one of the most widely used lifting solutions in workshops and factory buildings. It consists of a main girder, end carriages, an electric hoist, and an electrical system, with a lifting capacity range of 1–20 tons and standard spans from 7.5 to 31.5 meters. Kelude's LD Type electric single-girder bridge cranes are compatible with CD1/MD1 electric hoists and are well suited for machining, assembly workshops, warehousing, and logistics applications.

The above prices are ex-works reference prices including tax, excluding installation, rail, and electrical conductor rail costs. Actual quotations are determined based on span, lifting height, control mode (remote/handle/operator cabin), hoist model (CD1/MD1/HC differ by approximately 15%–25%), and other factors. For every additional 3 m of span, the main girder price increases by approximately 8%–12%; adding an operator cabin adds approximately $2,200–$4,400.
LD Type Single-Girder Bridge Crane Technical Specifications
Main Girder Structure: The LD type main girder features a box-section design with a built-in I-beam rail. The box material is Q235B (standard) or Q345B (for large spans/high-frequency duty). The top flange, bottom flange, and both web plates are welded using automatic submerged arc welding with H08A welding wire and HJ431 flux. After cutting, the main girder is pre-cambered (approximately L/600 to L/400), and the camber must pass inspection before the assembly proceeds to the next stage.
End Carriage Structure: The end carriages are welded box-section steel structures with wheel blocks mounted at both ends. The driving-side end carriage is equipped with an integrated three-in-one drive unit (motor, reducer, and brake combined), while the driven side is fitted with driven wheel blocks. The LD type crane bridge travel uses individual drive on each side, synchronized via variable-frequency drive (VFD) or soft starter.
Electrical System: Standard power supply is three-phase four-wire, 380 V/50 Hz. The hoisting motor is a conical rotor motor (ZDY or ZDⅠ type), and the bridge and trolley travel motors are conical rotor asynchronous motors. Control is via pendant (wired handle) or wireless remote control (optional). Electrical protection includes short-circuit protection, overload protection, undervoltage protection, zero position protection, and travel limit protection.
Safety Devices: Hoisting height limit switch (weight-type or screw-type), travel limit switches (at both ends of bridge and trolley travel), electronic overload limiter (comprehensive error ≤5%), hook latch, buffers (rubber or polyurethane), and earthing protection.

Frequently Asked Questions
Q: How much does the rail and installation cost for an LD type single-girder crane?
A: The rail cost includes both material and installation. P38 or P43 steel rail material costs approximately $44–$74/m, and installation costs approximately $15–$30/m (including rail clamps, fishplates, and expansion joints). For a 22.5 m span, the total rail length on both ends is approximately 45 m, bringing the combined rail and installation cost to roughly $2,700–$4,700. Foundation work is the customer's responsibility or can be outsourced to a civil contractor.
Q: Can a remote control and operator cabin be added to an LD type single-girder crane?
A: Yes, both can be installed simultaneously. Daily operations are primarily handled via remote control (offering flexible floor operation), while the operator cabin serves as a backup or for high-level maintenance tasks. The remote control has a range of 100–150 m (line of sight) and features an emergency stop and dual-crane interlock function.
Q: What is the warranty and after-sales service for single-girder cranes?
A: Kelude Heavy Industry offers a 12-month full-machine warranty (excluding wear parts), with free repair or replacement of faulty components during the warranty period. After the warranty expires, lifetime technical support is provided, and spare parts are supplied at cost. We respond within 24 hours nationwide and arrive on site within 48 hours. A free annual inspection is included, covering main girder camber measurement, rail wear detection, and electrical insulation testing.
Q: Which is more cost-effective: single-girder or double-girder bridge cranes?
A: For the same lifting capacity, an LD type single-girder crane is approximately 30%–50% cheaper than a QD type double-girder crane. For example, a 10 t/22.5 m LD single-girder crane costs approximately $8,900–$14,800, while a QD double-girder crane of the same capacity costs approximately $22,200–$37,000. However, double-girder cranes are better suited for higher capacities (QD up to 500 t) and higher work duty classifications (above A6). Selection should be based on actual lifting requirements. For a detailed comparison, refer to the comparison table in the LH type bridge crane selection guide.
Q: Can an operator cabin be installed on a single-girder crane?
A: Yes. LD type single-girder cranes come standard with floor remote control, and an optional standalone operator cabin (mounted on the left or right side) is available. Adding the cabin costs approximately $2,200–$4,400 and is suitable for high-level operation or large-span applications. Note that the factory building must reserve clearance space on one side of the rail for the cabin to travel.
Q: What is the maximum span available for an LD type single-girder crane?
A: Standard spans range from 7.5 m to 31.5 m, in 3 m increments (7.5/10.5/13.5/16.5/19.5/22.5/25.5/28.5/31.5 m). Spans exceeding 31.5 m require an LH type hoist double-girder design or a reinforced main girder. When selecting a span, measure the inside distance between factory building columns and subtract the safety clearance on each side (approximately 0.5–1 m per side), then choose the nearest standard span.
Q: How long does it take to install a single-girder crane?
A: From contract signing to delivery and installation, the standard production lead time for an LD type single-girder crane is approximately 20–35 days (depending on span and capacity), with installation and commissioning taking 3–7 days. This includes rail installation, conductor rail installation, electrical wiring, and load testing. Kelude Heavy Industry provides on-site installation services nationwide.
