The hatch cover gantry crane is a frame-type gantry crane custom-designed for the longitudinal movement of ship hatch covers. Featuring high efficiency and portability, it is widely used on various types of vessels and is suitable for harsh marine environments.
This crane can not only be used for the installation, dismantling, and maintenance of hatch covers, but also undertake cargo loading and unloading operations on the deck.
Additionally, other lifting equipment can be retrofitted on its top platform according to different requirements.
Key Features
The YFM hatch cover gantry crane comes with a host of outstanding features:
All types of hatch covers + multi-ship type adaptation, support customization
Exclusive design for ship working conditions, high strength, and corrosion resistance
The twin winch is raised and lowered synchronously, and the hatch cover opens and closes smoothly
The electric hoist is multi-purpose and covers the whole deck operation
Hydraulic/electrical dual control, a full range of international authoritative certifications
Well-known brand core components, high reliability, and long life
The opening and closing efficiency has increased by 30%+, and the cost reduction and efficiency increase have been significant

How to choose between electric and electro-hydraulic Hatch Cover Gantry Cranes?
Selection Principle: Choosing between Electric and Electro-Hydraulic Type requires prioritizing three core factors: operating conditions, performance needs, and O&M costs. The following targeted comparison and recommendations are designed to meet the specific requirements of marine and port operations.
| Comparison Dimension | Hatch Cover Gantry Crane - Electric | Hatch Cover Gantry Crane - Electro-hydraulic |
|---|---|---|
| Power Principle | The motor directly drives the hoist and traveling mechanism with a short mechanical transmission chain. | The motor drives the hydraulic pump, which transmits power through hydraulic oil to actuate the executive mechanisms. |
| Core Advantages | Simple structure, low energy consumption, low maintenance cost, and fast response speed. | Large lifting capacity, stable operation, strong overload protection, and precise speed regulation capability. |
| Core Limitations | Prone to impact under heavy-load conditions, limited speed regulation accuracy, and high-power motors required for high loads. | Regular maintenance of the hydraulic system requires slightly higher energy consumption, and oil viscosity to be considered in low-temperature environments. |
| Applicable Load | SWL ≤ 20 tons | Heavy loads (SWL≥ 20 tons) |
| Maintenance Difficulty | Low; only regular inspections of the motor, reducer, and electrical system are required. | Medium; regular replacement of hydraulic oil and seals, as well as pipeline leak detection, are necessary. |
| Initial Cost | Relatively low | Relatively high (hydraulic system increases hardware costs) |
Selection Recommendation:
- Electric Model – Ideal for small to medium load applications requiring low initial cost and minimal maintenance.
- Electro-hydraulic Model – Ideal for heavy load applications demanding high operational stability and accurate speed control.

FAQ
Q: What information do I need to provide when inquiring?
A: The following information is required: Load capacity, span, and lifting Height, Drive Mode and Drive Configuration, Certification Requirements, and Other Supplementary Requirements.
Q: What is your lead time?
A: Our usual lead time is 3.5 months, but it might be extended a bit according to different classification society certifications.
Q: What is your minimum order quantity (MOQ)?
A: Our minimum order quantity (MOQ) is 1 unit. The larger the order quantity, the more favorable the price will be.
Q: How do you ensure the crane's quality?
A: Our products will only be shipped after passing FAT(including no-load, load, and overload tests). We also provide a 2-year after-sales warranty period. Additionally, we can obtain inspection and certification from major third-party classification societies and provide the corresponding certificates, with successful cases available for reference.
Q: What are your payment terms?
A: Our standard payment method is telegraphic transfer (T/T), with 30% as the down payment and 70% as the progress payment. Terms are negotiable and adjustable based on actual circumstances.
Q: How do you transport the cranes?
A: We have two transport options: knocked-down parts in standard containers, or a full unit via cargo ship. We'll negotiate the exact method based on the crane's actual size.
