45-Ton Rail-Mounted Double-Girder Container Gantr | RFQ Sourcing Details

This 45-ton rail-mounted gantry (RMG) crane is presented as a double-girder container-handling system for loading, unloading, transferring and stacking containers in railway transshipment fields and large container storage yards.

The described assembly includes the main girder, rigid and flexible outriggers, trolley travel mechanism, lifting mechanism, crane travel mechanism, electrical system and operator cab.

The crane can be configured as a single-cantilever, double-cantilever or non-cantilever design to suit the yard layout, container storage method and vehicle flow.

The stated container-handling configurations cover 20-foot, 40-foot and 45-foot containers, with one listed configuration also covering double-20-foot handling. Available operating methods are pendant control, cabin control and remote control.

The listed power range is 110–480 V, 50 or 60 Hz, single- or three-phase, while technical tables also identify three-phase 380 V, 50 Hz configurations.

Published general specifications include an 18–35 m span, 5–15 m/min lifting speed, A5 or A7 work duty, frequency speed control and rainproof protection with a wind-speed alarm. Color options are yellow, orange, red or customized. Customization is stated as available.

Several values in the supplied information describe different crane models or configurable variants rather than one fully reconciled 45-ton specification. Capacity tables list 35, 41 and 70-ton container-crane options, while a separate MG-series table lists main capacities from 10 to 100 tons.

Span, lifting height, wheel count, wheel load, motor selection and operating speed also vary by configuration.

Buyers should therefore obtain an approved technical proposal that explicitly identifies the rated load, container spreader, span, lifting height, outreach, rail gauge, wheel loads, duty class, operating speeds and electrical standard for the intended project.

Certification entries identify CE, RoHS and ISO 9001, and the product information states that a machinery test report and outgoing inspection video are provided. Buyers should confirm which documents apply to the ordered crane and request copies for review before manufacturing or shipment.

The published warranty information is inconsistent: one section states 12–24 months, while another states 12 months after the cargo leaves the port. The final contract should define the exact warranty start date, duration, exclusions, spare-parts responsibility and service method.

Installation guidance, manuals, commissioning scope, civil and rail requirements, operator training, local regulatory acceptance and any engineer travel costs should also be agreed in writing.
