This case study covers Haitai Crane’s 40 ton single girder RTG crane (Rubber-tired Gantry Crane), exported to the USA in November 2023 for use at bridge and high-speed rail precast girder yards. Rail-free and tire-mounted, the crane relocates freely on site and is used to lift, flip, and move precast box girders and T-beams up to 40 metric tons. Its span is sized to straddle precast girder production lines and storage areas, supporting efficient, safe construction on U.S. highway and railway infrastructure projects.
Présentation du produit
Le 40 Ton Single Girder RTG Crane is a highly maneuverable, small-to-medium-sized material handling device that requires no rail installation. It moves freely on site using rubber tires and is primarily used for lifting, loading, unloading, and stacking light- to medium-duty loads. U.S. customers use this equipment at precast girder yards for bridges and high-speed rail projects: in highway and railway construction, the 19.8-meter span is ideal for spanning precast girder production lines and storage areas, and is used for lifting, flipping, and moving concrete box girders and T-beams weighing up to 40 tons.
Design Highlights of 40 Ton Single Girder RTG Crane for Sale
- Enveloping / side-hung trolley design: as a single-girder structure, the hoisting trolley wraps over and runs along the sides of the single main beam, ensuring structural stability for 40-ton heavy lifts while maximizing under-beam clearance.
- Large-diameter, heavy-duty rubber tires: multiple large rubber tires at the base, paired with a diesel generator set (or electric drive system) and steering mechanism, enable trackless relocation, crab travel, and 90-degree turns.
- Inverted-“U” rigid leg structure: the wide welded steel box-section legs, narrower at the bottom, provide excellent torsional and wind resistance, well suited to outdoor operation.
Multi-part wire rope reeving: the wire rope and heavy-duty hook suspended from the trolley use a multi-part reeving system to deliver the lifting power needed for smooth handling of heavy, large components.

About Haitai Crane: Strength & Qualifications
Haitai Crane specializes in the research, design, manufacturing, and export of gantry cranes, including single- and double-girder gantry cranes, rail-mounted gantry cranes, and rubber-tired gantry (RTG) cranes. Its products are widely used in ports and terminals, shipbuilding, precast component production, and highway and railway infrastructure projects that require heavy-duty material handling.
The company maintains integrated production capabilities spanning structural design, steel fabrication, electrical and hydraulic system integration, and whole-machine commissioning, allowing products to be custom-designed to a customer’s on-site span, load capacity, clearance height, and operating environment. Haitai Crane has a long-standing presence in overseas markets, with products exported to the USA and other countries and regions to provide crane solutions for highway, railway, bridge, and port infrastructure projects.

Frequently Asked Questions about 40 Ton Single Girder RTG Crane
Q1. Can the span and lifting height of this 40-ton single girder RTG crane be customized?
Yes. The 19.8-meter span was designed around the layout of the U.S. customer’s precast girder production line and storage area. Haitai Crane can customize the span, lifting height, clearance, and other specifications based on the on-site working conditions.
Q2. What are the advantages of a single girder RTG crane compared with a traditional double-girder gantry crane?
A single girder RTG crane has a lighter structure and lower cost, and requires no rail installation — it relocates freely, crab-travels, and makes 90-degree turns on rubber tires. This makes it well suited to precast girder yards, storage yards, and other medium-capacity applications where the work area or equipment position changes frequently.
Q3. What types of precast components is this crane suited to handling?
The equipment is primarily used to lift, flip, and move precast concrete components up to 40 metric tons, such as box girders and T-beams, and is widely used in the production and storage stages of highway, railway, and high-speed rail bridge projects.
Q4. How long does it typically take from order to export delivery?
Delivery timelines depend on factors such as crane capacity, span, and the degree of customization required. We recommend customers share detailed on-site parameters and technical requirements so Haitai Crane’s engineering team can assess the request and provide an accurate production and delivery schedule.
Q5. Does the equipment exported to the USA meet local safety standards and certification requirements?
Haitai Crane can design and configure equipment to meet the relevant safety standards of the target market. We recommend customers confirm specific certification requirements (such as ANSI/CE) with Haitai Crane’s technical team before placing an order, to ensure the equipment meets local usage and acceptance requirements.
