Overview:
This drawing is for a BMGO double girder semi-gantry crane, model BMGO 15/5t-25m-12m A6.
The crane is a double girder semi-gantry crane fitted with an NRT electric hoist and a cabin with air conditioner. A semi-gantry crane has one leg running on a ground-level rail and one end supported on an existing runway beam or building structure. This design is common for outdoor storage yards where one side of the yard already has a column or beam suitable for crane support, and the other side needs a ground-level leg with a wheel.
The crane is designed for handling gas tanks, oil tanks, and large pipes — typical pressure vessels and large diameter pipes used in the oil, gas, chemical, and energy industries. It has a 15 t main hook and a 5 t auxiliary hook, so it can handle heavy vessels with the main hook and use the auxiliary hook for smaller lifts or for tilting and positioning. The runway length is 150 m, which is a long outdoor storage yard for storing and moving these large items.
The crane uses cabin control with an air-conditioned cabin. In an outdoor yard, weather conditions can range from hot sun to cold wind, and the air conditioner keeps the operator comfortable and focused. Lifting speeds are 0.45/2.7 m/min for the main hook and 0.7/4.0 m/min for the auxiliary hook, with two-speed control for precise positioning of heavy vessels.

FAQ (BMGO 15/5t-25m-12m A6 Double Girder Semi-Gantry Crane Drawing)
Common questions about semi-gantry cranes, BMGO double girder semi-gantry cranes, NRT electric hoists, 15 t main hook, 5 t auxiliary hook, 25 m span, 12 m lifting height, cabin control with air conditioner, outdoor use, gas tank and oil tank handling, large pipe handling, and P43 rail.
1. What is a BMGO double girder semi-gantry crane?
A BMGO double girder semi-gantry crane is a lifting system with two main girders supported on one side by a ground-level leg that runs on a rail, and on the other side by a travel beam supported on an existing building structure or column. It is different from a full gantry crane (two ground legs) and from an overhead crane (both sides on elevated runway beams). BMGO semi-gantry cranes are used in outdoor storage yards, warehouses, and workshops where one side of the yard already has a beam or column suitable for crane support, and the other side needs a ground leg because the building structure cannot carry the full crane load.
2. Why does this semi-gantry crane have an air-conditioned cabin?
This crane is designed for outdoor use, where the operator is exposed to sun, heat, cold, wind, and rain. An air-conditioned cabin keeps the operator comfortable in all weather conditions, which improves concentration and safety during long shifts. The cabin is mounted on one side of the bridge with an access ladder. Cabin control also gives the operator a clear view of the load, which is important when handling large pressure vessels and pipes that need precise positioning.
3. What is an NRT electric hoist and how does it work on this crane?
NRT electric hoist is a type of wire rope electric hoist used on overhead and gantry cranes. The "NRT" designation refers to the hoist series and its design features, which typically include a compact frame, a two-speed lifting motor, a built-in travel mechanism, and a wire rope drum. On this semi-gantry crane, the NRT hoist is mounted on the trolley and handles the 15 t main hook and the 5 t auxiliary hook. Lifting speeds are 0.45 / 2.7 m/min for the main hook and 0.7 / 4.0 m/min for the auxiliary hook, giving the operator slow speeds for precise positioning and faster speeds for normal lifting.
4. What types of loads can this crane handle — gas tanks, oil tanks, and large pipes?
This crane is designed for handling gas tanks, oil tanks, and large pipes in an outdoor storage yard. These are typically pressure vessels and large diameter pipes used in the oil, gas, chemical, and energy industries. The 15 t main hook handles the heavier vessels, and the 5 t auxiliary hook handles smaller lifts or helps tilt and position the load. The 12 m lifting height and 25 m span give good coverage of the storage yard, and the 150 m runway lets the crane travel the full length of the yard to reach any storage position.
5. What does BMGO 15/5t-25m-12m A6 mean?
BMGO = double girder semi-gantry crane. "15/5t" = 15 t main hook, 5 t auxiliary hook. "25m" = 25 m span. "12m" = 12 m lifting height (12.5 m for the auxiliary hook). "A6" = ISO A6 duty class (M6). A6 is a medium to heavy duty class, suitable for outdoor storage yard use where the crane is working regularly but not continuously at full load.
6. Why are two-speed lifting speeds used on this semi-gantry crane?
The crane uses two-speed lifting — 0.45 / 2.7 m/min for the main hook and 0.7 / 4.0 m/min for the auxiliary hook. The slow speed is used for precise positioning and for the final approach when setting a heavy pressure vessel or a large pipe into place. The fast speed is used for normal lifting and lowering, which saves time over a long lift. This combination is common on cranes that handle heavy, delicate, or high-value loads like gas tanks and oil tanks, where accurate positioning matters.
7. What rail types are used on this semi-gantry crane?
This crane uses square bar 40×40 on the upper travel beam side and P43 rail (recommended) on the ground leg side. Square bar rail is a simple, low-cost rail type used for light and medium duty, while P43 is a standard crane rail profile that handles higher wheel loads and gives better running performance. The combination is chosen to match the wheel loads and the existing structure on each side of the crane. For outdoor use, both rails should be installed with proper drainage and corrosion protection.
8. What power supply does this semi-gantry crane need?
This crane runs on 3-phase, 440 V, 50 Hz. This covers the 1.5 / 9.5 kW main hoist motor, the 0.8 / 4.9 kW auxiliary hoist motor, the trolley travel motors, the long travel motors, the air conditioner, and the control system. If your site uses a different voltage or frequency, Yuantai can supply the crane with a custom power supply to match your local grid.
