رافعة جسرية نصفية أحادية العارضة

A single girder semi gantry crane is a lifting solution. This equipment combines ground-level tracks with overhead tracks, maximizing the use of workspace while reducing initial investment costs. It typically has a lifting capacity of 1–20 metric tons, a span of 5–20 meters, and a lifting height of 4–8 meters. It is widely used in the manufacturing, warehousing, and steel structure fabrication industries.

وصف المنتج

A single-girder semi-gantry crane is a hybrid lifting system. One leg of the crane runs on a ground track, while the other runs on an elevated track within the building. This design is intended to facilitate material handling while reducing structural requirements. Compared to رافعات جسرية, this design requires only a single ground track, which can significantly reduce civil engineering costs. Therefore, it is an excellent solution for facilities where one side of the workshop already has bridge crane tracks or the necessary structural support.

Typically, single-girder semi-gantry cranes are equipped with wire rope hoists or European electric hoists, which offer smooth lifting, precise positioning, and low maintenance requirements. In addition, the use of variable frequency drive (VFD) technology enhances operational stability and minimizes load sway during operation. Users can deploy these cranes for indoor operations or, depending on operational requirements, for outdoor operations as well.

Type of Single Girder Semi Gantry Crane

VOITTO Crane offers different types of single-girder semi-gantry cranes, allowing users to make flexible choices based on their lifting requirements.

Standard Single Girder Semi Gantry Crane: This configuration is specifically designed for general manufacturing applications and is equipped with a wire-rope electric hoist as the lifting mechanism, with a lifting capacity of up to 20 tonnes, suitable for medium-duty operation. This type represents an economical crane solution.

European Type Semi-gantry Crane: Compared with traditional standard semi-gantry cranes, this equipment utilises a compact, low-headroom hoisting mechanism, a structural design optimised in accordance with FEM standards, and high-strength steel, thereby offering advantages such as a lighter dead weight, lower wheel load, quieter operation and greater energy efficiency.

تطبيق المنتج

A single girder semi gantry crane is widely used for material handling operations involving light to medium loads. This equipment is particularly suitable for situations where gantry cranes cannot be installed due to spatial or structural constraints. Below are some common applications of semi-gantry cranes.

• Machining Workshops and Light Steel Structure Workshops: Users use this equipment to lift and handle small- to medium-sized workpieces, moulds, steel plates, sections, and raw materials.
• Automotive Component Factories: Operators use this equipment to lift and handle engines, vehicle chassis, and other components.
• Logistics Warehouses and E-commerce Sorting Centres: Users operate this equipment to lift and handle pallets, cartons, and packaged goods.
• Railway Freight Yards and Road Transhipment Stations: This equipment is used to assist in the handling of small and medium-sized containers or bulk cargo.
• Building Materials Markets and Sheet Material Processing Plants: Users employ this equipment to lift stone, glass, precast panels, and materials of substantial length and width.
• Paper Mills and Textile Mills: Operators control this equipment to lift paper rolls, fabric rolls, and other roll-form materials.
• Small-scale Construction Sites: Users employ this equipment to lift precast concrete components and building materials.

الأجزاء والمكونات

A semi-gantry crane consists of several integrated components; its main structure comprises a single girder, outriggers, a lifting system, end beams, an electrical system, and travel mechanisms. These components operate in unison to carry out material lifting tasks.

• الشعاع الرئيسي: This component supports the hoisting mechanism and bears the lifting load across the span.
• أذرع التوازن: These support one side of the crane and run along the ground rails.
• Ground Travel Mechanism: This drives the crane to move smoothly along the ground rails.
• Elevated Rail Travel Mechanism: This drives the crane to move along the elevated rail girders.
• Hoisting System: This component is responsible for lifting and lowering materials.
• مجموعة الخطاف: Used to grip and lift loads during operations.
• عارضة طرفية: Connects the main girder to the running wheels.
• Rail System: Guides the crane along its path.
• Electrical Control Cabinet: Controls the crane’s electrical system and power distribution.
• أجهزة السلامة: Ensure the safety of the crane and operators during hoisting and travel.
• نظام التحكم: Controls the crane’s hoisting and travel movements via a joystick or remote control.

الأسئلة الشائعة

What is a single girder semi gantry crane?

A single girder semi-gantry crane is a lifting system supported by one ground-running leg and one overhead runway. It combines the advantages of overhead and gantry cranes while reducing construction costs and maximizing workshop space utilization.

How is a semi gantry crane different from a full gantry crane?

A semi gantry crane requires only one ground rail because its opposite side travels on an existing building runway. As a result, it uses less structural steel, occupies less floor space, and generally costs less to install.

Can a single girder semi gantry crane be used outdoors?

Yes. Outdoor models include weather-resistant coatings, wind protection devices, sealed electrical components, and corrosion-resistant finishes. Therefore, they perform reliably in storage yards, construction sites, and outdoor production facilities.

Which industries commonly use semi gantry cranes?

Manufacturing, steel fabrication, logistics, warehousing, machinery assembly, maintenance workshops, construction material yards, and equipment processing facilities commonly use semi gantry cranes because they provide flexible and efficient material handling.
