They needed to reach both sides of the runway as well as the area between the rails. Some load handling positions were below rail level, so both hooks needed enough downward travel to reach them.<\/p>\n\n\n\n<ul>\n<li>Ambient temperature: \u221245\u00b0C to +40\u00b0C in both operating and non-operating conditions.<\/li>\n\n\n\n<li>Lifting capacity and duty: A 32 t main hook and a 12.5 t auxiliary hook on each crane, with an overall A6 duty classification. Hoisting, trolley travel, and gantry travel all required variable speeds.<\/li>\n\n\n\n<li>Horizontal reach: A 32 m span with a 12.5 m cantilever at each end.<\/li>\n\n\n\n<li>Vertical reach: The main hook can lift 10 m above rail level and the auxiliary hook 11 m.

The material provides the strength required to carry the loads and low-temperature impact toughness to help reduce the risk of brittle fracture under impact.<\/li>\n\n\n\n<li><strong>Heaters for hoist and travel motors.<\/strong> The main hoist, auxiliary hoist, trolley travel, and gantry travel motors all have anti-condensation heaters. These help keep the motor interiors warm when stopped, reducing the risk of condensation as the motors cool and helping protect the winding insulation.<\/li>\n\n\n\n<li><strong>Heated, insulated operator cabin.<\/strong> The enclosed operator cabin is mounted beneath the hoist trolley and travels with it. The enclosure limits air exchange, insulation reduces heat loss, and the heater supplies warmth for the operator.<\/li>\n<\/ul>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.hndfcrane.com\/wp-content\/uploads\/2026\/11\/russia-gantry-crane-box-girders.jpg\" alt=\"Box girders in the fabrication workshop\"\/><figcaption class=\"wp-element-caption\">Main girder made of Q355E steel<\/figcaption><\/figure>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-1 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.hndfcrane.com\/wp-content\/uploads\/2026\/11\/russia-gantry-crane-hoist-trolley.jpg\" alt=\"Hoist trolley and drive assemblies\"\/><figcaption class=\"wp-element-caption\">Hoisting motor with heater<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.hndfcrane.com\/wp-content\/uploads\/2026\/11\/russia-gantry-crane-travel-bogies.jpg\" alt=\"Gantry travel bogies\"\/><figcaption class=\"wp-element-caption\">Traveling motor with heater<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"dual-hook-lifting-32-t-main-hook-12-5-t-auxiliary-hook-and-variable-speeds\">Dual-Hook Lifting: 32T Main Hook, 12.5T Auxiliary Hook, and Variable Speeds<\/h3>\n\n\n\n<p>Each crane has two hoisting mechanisms. The 32 t main hook handles heavier loads, while the 12.5 t auxiliary hook handles loads within its own rated capacity. The overall crane duty class is A6. The main hoist and gantry travel mechanisms are M6; the auxiliary hoist and trolley travel mechanisms are M5.<\/p>\n\n\n\n<p>The speed ranges are:<\/p>\n\n\n\n<ul>\n<li>Main hoist: 0.95\u20139.5 m\/min<\/li>\n\n\n\n<li>Auxiliary hoist: 1.33\u201313.3 m\/min<\/li>\n\n\n\n<li>Trolley travel: 3.7\u201337 m\/min<\/li>\n\n\n\n<li>Gantry travel: 3.2\u201332 m\/min<\/li>\n<\/ul>\n\n\n\n<p>The auxiliary hook can lift faster within its rated capacity. Near the set-down point, the operator can use a lower hoisting speed to adjust hook height and use trolley and gantry travel to position the load horizontally.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"working-range-32-m-long-span-design-with-12-5-m-double-side-cantilevers\">Working Range: 32 m Long-Span Design with 12.5 m Double-Side Cantilevers<\/h3>\n\n\n\n<p>We employ a gantry with a 32m span, featuring 12.5m cantilevers on each side of the main girder, providing a total lateral coverage of 57 meters. The trolley can travel from within the span onto either cantilever, allowing the hooks to reach pickup and set-down points outside the rails. For example, the crane can pick up materials from outside the runway and move them inward for placement, or move a load from inside the span out to a cantilever for unloading.<\/p>\n\n\n\n<p>Both hoists can lower 10 m below the gantry rail level. Using rail level as the reference, the main hook can lift 10 m above it and the auxiliary hook 11 m above it.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"double-girder-gantry-cranes-packing-and-shipment\">Double Girder Gantry Cranes Packing and Shipment<\/h2>\n\n\n\n<p>Before shipment to Russia, we packed the equipment according to each component\u2019s dimensions, shape, and protection needs. The box girders, legs, and travel mechanisms were shipped separately. The long girders were placed lengthwise on the vehicles and secured with straps to limit movement in transit. Protective covers were fitted to the mating faces of selected girder sections to reduce the risk of impact during handling and loading.<\/p>\n\n\n\n<p>The hoist trolley was covered with a tarpaulin to protect its exposed mechanisms. Cabin glass and smaller components were packed in wooden crates to protect them from impacts during loading, unloading, and transport.<\/p>\n\n\n\n<p>The shipment included Russian-language technical passports, general arrangement drawings, and electrical drawings to help the site team check assembly positions and electrical connections when the equipment arrived.<\/p>\n\n\n\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.hndfcrane.com\/wp-content\/uploads\/2026\/11\/russia-gantry-crane-trolley-shipment.jpg\" alt=\"Tarpaulin-covered trolley secured for shipment\"\/><figcaption class=\"wp-element-caption\">Tarpaulin-covered trolley secured for shipment<\/figcaption><\/figure>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-2 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.hndfcrane.com\/wp-content\/uploads\/2026\/11\/russia-gantry-crane-components-on-truck.jpg\" alt=\"Packed crane components loaded on a truck\"\/><figcaption class=\"wp-element-caption\">Packed crane components loaded on a truck<\/figcaption><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\">\n<figure class=\"wp-block-image\"><img decoding=\"async\" src=\"https:\/\/www.hndfcrane.com\/wp-content\/uploads\/2026\/11\/russia-gantry-crane-girder-shipment.jpg\" alt=\"Gantry crane girder and travel assembly prepared for transport\"\/><figcaption class=\"wp-element-caption\">Gantry crane girder and travel assembly prepared for transport<\/figcaption><\/figure>\n<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"selecting-a-gantry-crane-for-a-cold-weather-site\">Selecting a Gantry Crane for a Cold-Weather Site?<\/h2>\n\n\n\n<p>If your project involves lifting materials in a cold climate, tell us what you need to lift and where the crane will operate.
