LH Type Electric Hoist Overhead Crane: Specs & Selection Guide
Key Points The LH-type electric hoist overhead crane (twin-girder hoist crane) offers a lifting capacity of 5–32t, spans of 10–30m, and lifting heights of 6–24m, featuring a twin main girder design with an electric hoist hoisting mechanism. Reference pricing: 5t approx. $12,000–$22,000, 10t approx. $18,000–$33,000, 20t approx. $33,000–$56,000, 32t approx. $44,000–$82,000. Positioned between the LD-type (single girder) and QD-type (double-girder winch) cranes, it suits medium-duty applications. Units with a lifting capacity of 3t and above fall under special equipment regulation.
The LH-type electric hoist overhead crane—also referred to as the LH-type twin-girder hoist bridge crane—is a mid-tonnage solution that bridges the gap between LD-type single-girder cranes and QD-type double-girder winch cranes. Built with twin main girders for load-bearing support and an electric hoist as the hoisting mechanism, it delivers the required lifting capacity and span while keeping equipment costs in check. This makes it a popular choice for medium-duty applications demanding 5–32t lifting capability, including machine shops, assembly workshops, warehousing and logistics, and small-to-medium steel structure workshops.
This article provides a complete breakdown of LH-type electric hoist overhead crane specifications, pricing, and selection guidance across key dimensions such as technical parameters, price ranges, structural features, and selection criteria—helping procurement and engineering teams quickly match the right model to their needs.
Technical Parameters Explained
The core parameters of the LH-type twin-girder hoist bridge crane span multiple dimensions, including lifting capacity, span, lifting height, work duty, and travel speeds. Configuration varies by model, so selection should always be based on the specific operating conditions at hand.
Lifting Capacity and Span Overview: Standard lifting capacities for the LH-type are 5t, 10t, 16t, 20t, and 32t. Spans range from 10m to 30m in 3m increments. Standard lifting height is 6–24m, with custom heights available based on building clearance. The work duty classification is A3 to A5, suitable for light-to-medium and medium duty lifting cycles.
Travel Speeds: Lifting speed is available in single-speed (3.5–7m/min) or two-speed (7/0.7m/min) configurations. Long travel speed ranges from 20–45m/min, while cross-travel speed is 20m/min. The two-speed option provides better control for precise positioning and light-load hoisting.
Hoisting Mechanism: The crane uses either a CD1/MD1 electric hoist or an HC-type square box hoist. The CD1 is a single-speed hoist, the MD1 is a two-speed hoist, and the HC-type square box hoist is engineered for heavier loads and more frequent duty cycles.
Operation Mode: Standard configuration includes floor-mounted remote pendant control. An optional independent operator cab (left- or right-mounted) is available, offering better visibility at the expense of a higher overall equipment price.
Price Reference by Model
The price of an LH-type electric hoist overhead crane is influenced by a combination of factors, including lifting capacity, span, lifting height, operation mode, hoist type, electrical configuration, and crane rail length. Below are reference price ranges from Kelude for each model in standard configuration (floor remote control, standard span, standard lifting height):
- 5t LH-type electric hoist overhead crane: approx. $12,000–$22,000
- 10t LH-type electric hoist overhead crane: approx. $18,000–$33,000
- 16t LH-type electric hoist overhead crane: approx. $27,000–$44,000
- 20t LH-type electric hoist overhead crane: approx. $33,000–$56,000
- 32t LH-type electric hoist overhead crane: approx. $44,000–$82,000
Prices above are ex-works and include tax, but exclude installation, transport, crane rail, and electrical busbar costs. Final quotations are calculated on a case-by-case basis depending on specific parameters and operating environment. Adding an operator cab typically increases the price by $3,000–$7,500, and upgrading from a CD1 hoist to an HC-type square box hoist adds approximately 15%–25% to the cost.

Selection Recommendations: For lifting capacities between 5–20 t with moderate duty cycles (Work Duty A3–A4), the LD type is a suitable choice. If you need 5–32 t capacity with the added stability of twin-girder support (Work Duty A3–A5), the LH type is preferred. For capacities above 32 t or duty classifications of A6 or higher, the QD type should be selected.
Structural Features
The LH-type hoist bridge crane offers the following key structural advantages:
- Twin Main Girder Box Construction: The main girders feature a welded steel plate box cross-section, delivering high strength, excellent rigidity, and strong torsional resistance. Compared to the LD single-girder design, the twin-girder configuration provides superior stability and reliability when handling heavy or oversized loads.
- End Carriages and Travel Mechanism: The end carriages are fabricated from welded steel plate and come equipped with both driven and idler wheel blocks. The bridge travel uses an individual drive system on each side, ensuring synchronized movement with smooth acceleration and braking.
- Electric Hoist Lifting Mechanism: The electric hoist is suspended beneath the trolley frame and travels along rails mounted on the main girders. The hoist is available as a CD1/MD1 model or an HC-type square box hoist, with the hoist gearbox and motor integrated into a single compact unit for easy maintenance.
- Safety Devices: Standard equipment includes a hoisting height limit switch, travel limit switches, overload limiter, buffers, and hook latches. LH-type cranes with a capacity of 3 t or more are classified as special equipment and must pass supervision inspection before delivery. Users are required to schedule periodic inspections with their local special equipment inspection authority.
Kelude Heavy Industry maintains strict control over welding quality and assembly precision throughout the structural design and manufacturing of LH-type hoist bridge cranes, ensuring every unit meets applicable national standards and user requirements.
Selection Guide
When selecting an LH-type electric hoist bridge crane, work through the following steps in order:
- Determine Lifting Capacity: Start with the actual weight of your heaviest load, apply a safety factor of 1.1–1.25, and round up to the nearest standard tonnage (5/10/16/20/32 t). For example, a maximum load of 8 t would call for a 10 t crane.
- Determine Span: Measure the clear distance between the inner faces of your building columns, subtract a safety margin of approximately 0.5–1 m on each side, and select the nearest standard span. Larger spans require deeper main girder cross-sections, which increases cost.
- Confirm Lifting Height: Measure the vertical distance from the floor to the highest hook position, then add clearance for the hook and lifting spreader. Select a standard value within the 6–24 m range; heights above 24 m require a custom design.
- Choose Operation Mode: Floor-mounted remote control (standard) is ideal when the operator needs to follow the load on the ground. A cabin is recommended for high-level operation, applications requiring a clear field of vision, or long-span installations — allow space alongside the building columns for cabin access.
- Select Hoist Type: The CD1/MD1 hoist is the standard recommendation for cost-effective performance. For capacities of 20 t or more with frequent duty cycles (approaching A5), the HC-type square box hoist is recommended, as its hoist gearbox and drum design are better suited to heavy-load operation.
- Confirm Work Duty: Select A3, A4, or A5 based on average daily lifting cycles and load factor. Higher duty classifications require larger safety margins in the motor and structural components, which increases the unit price.
