10 Ton Portable Gantry Crane for Steel Plate Handling in Oman

An Oman-based customer purchased a portable gantry crane for handling steel plates. We paired a portable gantry crane with an electric chain hoist that travels along the beam: the gantry moves between work areas, while the hoist positions the hook and lifts the plates. After the drawing was approved, English pendant labels, electrical connectors, and separate component packaging were carried out according to the order. The equipment is now in the packaging and shipment preparation stage.

Steel Plate Handling Requirements

The customer purchased the portable gantry crane to handle steel plates. Beyond the equipment configuration, we also had to plan how the crane would be shipped to Oman in separate parts and how those parts would be checked, connected, and assembled on site. The agreed operating method and delivery requirements led to three priorities:

• Move the steel plates: The equipment needed to lift and reposition the plates and remain useful when the work location changed.
• Simplify operation and assembly: The customer needed to identify the electrical connections between components and understand the pendant commands clearly.
• Protect the equipment in transit: The hoist, electrical parts, and gantry steelwork needed protection during separate shipment, with parts easy to check on receipt.

Our Solution for the Project

Technical Specifications

• Rated capacity: 10 ton
• Span: 4 m
• Lifting height: 5 m
• Lifting speed: 2.7 m/min
• Hoist travel speed: 11 m/min
• Gantry crane travel speed: 10 m/min
• Power supply: 380 V, 50 Hz, three-phase
• Control: pendant, with English labels

Rail-Free Travel Across Work Areas

• Rail-free travel across different areas: The gantry moves on wheels rather than following the direction and length of a fixed track. The wheels support 360° steering, allowing the customer to adjust the travel route around the plate pick-up and drop-off points, and workshop aisles. One crane can therefore serve different plate storage and work areas.
• Less track construction and site modification: The equipment does not require a fixed runway or the associated track installation and foundation work. If the plate-handling area changes, the customer can move the gantry instead of extending or rearranging a track. This reduces the time and expenditure associated with track laying and related site work.

Hook Alignment, Smooth Lifting, and Safety Controls

• Adjust the hook without moving the whole gantry: The electric chain hoist travels along the beam on a trolley. If the hook is not directly above the plate lifting attachment or the intended drop-off point, the customer can move the hoist for a small adjustment rather than repeatedly repositioning the entire gantry.
• Smooth chain travel reduces jolting during lifting: The high-strength chain is heat-treated and pre-stretched. Its pitch matches the chain wheel profile, helping the chain run more smoothly during lifting and lowering while reducing jolting and noise.
• Power-off braking and upper and lower limits protect the lift: When operation stops or power fails, the normally closed brake engages automatically to prevent the plate from continuing to descend. The upper limit stops lifting as the hook approaches its highest position; the lower limit stops lowering near the end of chain travel, helping prevent the hook from striking the hoist or the chain from leaving the chain wheel.

Labeled Plug-In Electrical Connections Simplify Assembly

Because the portable gantry crane is shipped in separate parts, its beam, hoist, travel mechanisms, and electrical controls must be connected again on site. Before shipment, we completed the electrical prewiring and brought multiple power and control wires together in matching multipin plug connectors. This allows the customer to connect a group of circuits with one plug connection and helps prevent reversed or mismatched connections.

We also labeled the corresponding connectors. On arrival, the customer can identify each matching interface, plug it in, and then check the operation of each mechanism. This reduces the need to trace and connect individual wires on site. If the hoist, control box, or travel mechanism needs to be removed later, its connector can be unplugged without disconnecting every wire, then reconnected according to the labels. English labels on the control pendant help the customer distinguish the operating commands.

Reinforced Wooden Crates Protect Components in Transit

• Separate packing for easier checking and assembly: We packed the electric chain hoist, electrical accessories, and travel drive parts separately, wrapped the gantry steelwork, and marked the wooden crates with their corresponding contents. Keeping electromechanical parts apart from the longer steel members reduces direct contact and abrasion during handling. The wrapping helps protect the painted steel surfaces from scratches. On receipt, the customer can check the crates and locate the hoist, drive, and electrical parts more quickly.
• Reinforced crates reduce compression risk: The wooden crates use external angle-steel protection or internal supports to keep the tops flat and capable of bearing weight. External steel angles reinforce the corners, while internal supports distribute pressure on the crate panels. This helps reduce the risk of the crate top deforming and compressing the parts inside. The crate shown in the photo has an external angle-steel frame.

Before shipment, we also need to record the accurate weight and dimensions of each item and prepare a packing list. The customer can use it to arrange transport, check the number of crates and their contents on receipt, and find the required parts during assembly.
