Haitai delivered a 40 ton hydraulic straddle carrier to a port operator in Mongolia, supporting efficient heavy-load cargo handling at the site. The container carrier features a robust hydraulic system designed for reliable performance in demanding port environments. This case study outlines the customer’s challenges, Haitai’s tailored solution, and the successful delivery and operation of the equipment in Mongolia.
Background: A Growing Demand for Heavy-Duty Straddle Carriers in Mongolia
Mongolia’s logistics sector has seen rapid expansion over the past decade. As cross-border trade with China and Russia intensifies, cargo handling at inland ports and dry ports has become a critical bottleneck. Traditional forklifts and overhead cranes struggle to keep pace with heavier container volumes and tighter turnaround requirements. This is where a heavy-duty 40 ton hydraulic straddle carrier becomes a decisive upgrade.
The client is a Mongolia-based port logistics operator. He was handling steel coils, oversized containers, and prefabricated modules daily, often exceeding 30 tons per lift cycle. Their existing equipment was aging and underspecced for the load demands. After evaluating multiple straddle carrier suppliers from China and Europe, they selected Haitai Crane as their 40 ton hydraulic straddle carrier equipment partner.
Client Project Requirements of 40 Ton Hydraulic Straddle Carrier
Before any design work began, the Haitai engineering team conducted a detailed needs assessment with the Monglian client.
The Requirments they need:
- Need a 40 ton straddle carrier solution with hydraulic drive, not electric.
- Span width of 8.5 meters to straddle standard shipping containers
- Lifting height of 4.5 meters, and full hydraulic steering for tight-aisle maneuverability
- load cycles averaging 18-22 lifts per shift
- extreme seasonal temperatures ranging from -35°C in winter to +38°C in summer
- Handle the terrain in an open yard environment with unpaved sections, and eliminate dependence on centralized power infrastructure.
The Haitai team mapped these requirements directly to a configurable product platform, shortening the engineering cycle from the standard 90 days to 65 days.

Why the Client Chose a Hydraulic Straddle Carrier Over an Electric Straddle Carrier?
| Comparison Criteria | Hydraulic Straddle Carrier | Electric Straddle Carrier |
|---|---|---|
| Drive System | Diesel Engine/Motor + Hydraulic Pump and Hydraulic Motor | Battery/Generator + AC Inverter Motor |
| Environmental Impact and Noise | High noise levels, exhaust emissions (unless hybrid electric-hydraulic) | Zero emissions, low noise, meets environmental standards |
| Maintenance Costs | Requires regular hydraulic oil changes, leak prevention, and complex maintenance | Few maintenance points, simple upkeep |
| Load Capacity and Power | Powerful performance, suitable for heavy-duty operations with ultra-high tonnage (e.g., 100 tons or more) | Quick response, suitable for light to medium loads or automation upgrades |
| Control Precision | Valve-controlled for smooth operation, but with slight lag | PLC control ensures precise fine-tuning of travel and lifting |
| Tire Wear | Hydraulic steering systems are stable when properly matched, but require strict pressure control in the hydraulic lines | Driven by differential or independent motors, resulting in minimal tire wear |
The decision to choose hydraulic straddle carrier rather than battery-electric straddle carrier was driven by three practical factors:
- First, the Mongolia project site lacked a reliable 3-phase power supply in the open yard area. Installing the electrical infrastructure alone would have added significant cost and time.
- Second, hydraulic straddle carriers perform consistently in extreme cold, where lithium battery performance degrades sharply below -20°C.
- Third, the maintenance team on-site had experience with diesel-hydraulic machinery but no background in EV powertrain servicing.
A heavy-duty 40 ton hydraulic straddle carrier built around a proven Cummins diesel engine and a German-designed hydraulic system reduced the technical risk for the client. The total cost of ownership over five years — factoring in fuel, maintenance, and parts availability — was also competitive with comparable electric models, particularly given Mongolia’s current energy infrastructure.
How Did HT Crane Manage the Export and Delivery to Mongolia?
Exporting port cargo handling equipment to Mongolia presents logistical challenges that differ from coastal shipping. The delivery route followed a road-rail combination: factory in China to Erlian (Erenhot) border crossing, then rail into Ulaanbaatar, followed by road transport to the project site. Total transit time was 22 days from factory gate to site.
Haitai’s export team pre-coordinated customs documentation including the certificate of origin, packing list, commercial invoice, and CE conformity declaration. All structural components were shipped partially disassembled to comply with road dimension restrictions at the border. On-site Haitai technicians handled reassembly and commissioning over four days. The client’s operators received a structured 16-hour training program covering daily inspection routines, load chart compliance, and hydraulic system fault diagnosis. Equipment delivered successfully within the agreed schedule.
On-Site Performance: Results After 6 Months of Operation
Six months after commissioning, the client reported measurable improvements across key performance indicators. Average yard throughput increased by 34% compared to their previous mixed-equipment setup. Unplanned downtime dropped to less than 1.5% of total operating hours — well within the industry benchmark of 3%.
The 40 ton hydraulic straddle carrier handled steel coil bundles and 40-foot HC containers interchangeably without reconfiguration. The only maintenance intervention during this period was a routine hydraulic fluid change at the 500-hour mark, completed by the on-site team using locally sourced Haitai-approved fluids.
The client confirmed that the Cummins engine performed reliably through a -28°C winter period without cold-start issues, validating the design selection. This customer success story has since been cited by two other Mongolia logistics project operators currently in early-stage procurement discussions with Haitai.

Frequently Asked Questions (FAQ)
Q1. What is the lead time for a 40 ton hydraulic straddle carrier from HT Crane?
Standard production lead time is 60 to 90 days from order confirmation, depending on configuration and current factory scheduling. For the Mongolia project, Haitai completed manufacturing in 65 days due to the client’s modular spec matching an existing platform design. Buyers with urgent timelines should discuss factory slot availability and partial prefabrication options during early-stage inquiry. Providing complete technical requirements — span width, lifting height, operating temperature, and load type — upfront can reduce engineering review time by two to three weeks.
Q2. Can the hydraulic straddle carrier handle both containers and irregular heavy cargo?
Yes. Haitai’s 40 ton hydraulic straddle carrier is designed for versatile cargo handling, including ISO containers, steel coils, timber bundles, and oversized modules. The lifting beam can be configured with spreader attachments for standard container handling or flat beam adapters for irregular load profiles. The Mongolia client uses the same unit for both 40-foot HC containers and steel coil bundles without swapping hardware. Haitai recommends specifying your primary cargo type during procurement to ensure the correct spreader geometry and hydraulic pressure settings are pre-configured at the factory.
Q3. What after-sales support does Haitai provide for equipment delivered to Mongolia?
Haitai provides a 12-month on-site warranty covering all mechanical and hydraulic components. For Mongolia and Central Asia clients, the after-sales program includes a remote diagnostic service via telematics, a spare parts package shipped with the machine covering consumables for the first 1,000 operating hours, and access to a Mandarin and English-speaking technical support hotline. For major repairs beyond the local team’s capability, Haitai can dispatch a field engineer to Mongolia within five to seven business days. Clients are also enrolled in Haitai’s annual maintenance reminder program to prevent early-stage wear from escalating.
Q4. How does Haitai handle export documentation and customs clearance for Mongolia?
Haitai has an in-house export compliance team experienced with the China-Mongolia trade corridor via Erlian/Erenhot. Standard documentation includes the commercial invoice, packing list, certificate of origin (Form A or RCEP-eligible), CE declaration of conformity, and customs HS code classification support. For oversized or over-weight components, Haitai coordinates transport permits in advance. Buyers are responsible for Mongolia-side import duties and local customs clearance, but Haitai provides a detailed shipping advisory document to support the process. Experience from past Mongolia logistics project deliveries means documentation errors — the most common cause of border delays — are effectively pre-screened.
Q5. What factors most affect heavy-duty straddle carriers price for port applications?
The four primary cost drivers for a heavy-duty straddle carrier are: rated capacity (ton class), span and lifting height combination, engine brand (Cummins vs. DEUTZ vs. domestic alternatives), and certification requirements (CE adds engineering overhead). Secondary factors include tyre specification (solid rubber off-road tyres cost more than standard pneumatic), spreader type, and telematics or load moment indicator packages. For Mongolia or similar markets, buyers should also budget for export packaging, inland freight to the border, and commissioning costs. Haitai offers tiered pricing models — base machine, standard package, and full turnkey — to fit different procurement structures.
