Bộ dụng cụ cẩu trục dầm đôi 20 tấn và 30 tấn cho Ai Cập: Tiết kiệm chi phí vận chuyển 20% (không bao gồm dầm chính)

We supplied NLH 20 t and NLH 30 t double girder overhead crane kits to a customer in Egypt. Both cranes have a 17 m span. The customer will fabricate the main girders locally. We provided separate main girder fabrication drawings and supplied the hoisting trolleys, end carriages and long travel drives, electrical systems, conductor rails, and wear parts.

The Customer Needed 20T and 30T Double Girder Overhead Crane Kits

The customer plans to fabricate the main girders locally and requires 20 t and one 30 t double-girder overhead crane kits, both with a span of 17 meters. The scope of supply includes the hoisting trolley, end carriages, long-travel drive mechanisms, and electrical systems; we will also provide the fabrication drawings for the main girders.

• Equipment: one NLH 20 t crane and one NLH 30 t crane
• Span: 17 m for each crane
• Controls: wireless remote control and wired pendant
• Power supply: three phase, 380 V, 50 Hz; control voltage 48 V
• Each crane includes conductor rails and accessories, plus one set of wear parts

Local Girder Fabrication with Our Drawings Saves 20% on Shipping Costs

We offered a solution in which the customer fabricates the main girders locally and purchases only the overhead crane kits from us. We provide the girder fabrication drawings, allowing the customer to avoid cross-border shipping of four main girders, each approximately 17 meters long. With an FOB Qingdao price of approximately USD 39,000, this solution is expected to reduce the customer’s shipping costs by around 20%.

Main Girder Fabrication Drawings for the 20 t and 30 t Cranes

Separate main girder fabrication drawings were supplied for each crane so the customer can arrange local fabrication. Both cranes have a 17 m span, measured as the center distance between the two long travel runway rails. The trolley gauge is 2.4 m on both cranes, measured between the trolley rails on the two main girders. The drawings show the end carriage connection interfaces and mounting space for the hoisting trolley and walkway.

The general arrangement drawings specify 40 × 60 mm trolley rails for both cranes and P30 runway rails. Wheel loads are 67 kN for the 20 t crane and 95 kN for the 30 t crane. Use the relevant wheel load when checking runway beams and supports.

Same Travel Speeds, Different Hoisting and Drive Configurations

Both cranes use two speed hoisting. The slower speed supports precise positioning, while the faster speed can be used for routine lifting when appropriate. The trolley moves the load across the bridge; the long travel drive moves the crane along the runway.

The 30 t crane has higher power trolley and long travel motors. Both cranes can be operated by wireless remote control or wired pendant for hoisting, cross travel, and long travel.

Conductor Rails and Wear Parts Supplied with the Cranes

We supplied a four pole enclosed conductor rail system rated at 400 A. Each pole is 101.1 m long, for a total of 404.4 m across all four poles, with the required accessories. The rails run along the runway, and a collector mounted on the crane draws power as it travels.

Each crane includes one set of wear parts. Hoisting mechanism spares include a rope guide, a complete wire rope, and a hoisting motor brake disc. Electrical spares include contactors, and hook spares include safety latches. The parts are listed by crane capacity so the customer can check each set on receipt and select the correct parts during maintenance.

Shipping and Packing the Double Girder Overhead Crane Kits

Before shipment, we packed and secured the components to protect them during transit. End carriages and trolley frames were wrapped in protective film and fastened with straps to prevent movement, impact, and abrasion. Conductor rails and electrical accessories were packed in wooden cases for protection against crushing and impact.

Planning to Fabricate the Main Girders Locally?

Where suitable local steel fabrication resources are available, we can supply the crane without the main girders. The customer can fabricate the girders to the drawings while we configure the hoisting trolleys, end carriages, and long travel drives to match rated capacity and building conditions. Conductor rails, controls, and wear parts can also be included according to project requirements.

For a quotation, please provide the rated capacity, span, lifting height, available headroom, runway rail specification, and power supply. Identify which components will be fabricated locally so we can confirm connection interfaces, define the drawing and equipment scope, and prepare a quotation.
