وصف المنتج

Semi-رافعات جسرية employ a special structural design to adapt to various lifting operation environments.  On one side, the bridge frame runs along an overhead rail, similar to a bridge crane. At the other end, outriggers support the crane, with its end beams resting on the ground and moving on rubber tires or rail-mounted wheels. Compared to standard gantry cranes, it eliminates the need for a supporting gantry leg on one side, reducing costs and expanding the crane's effective working space.

Semi-gantry cranes are suitable for both indoor and outdoor use. Various lifting tools, such as grab buckets and electromagnets, can be selected under the hook.

Types of Semi-Gantry Cranes

Nucleon provides semi-gantry cranes in two types (single-girder semi-gantry cranes and double-girder semi-gantry cranes) and various configurations. Each type can meet your specific lifting needs. Let's take a closer look.

BMH Single Girder Semi Gantry Cranes  handle light to medium-duty lifting operations, with capacities typically ranging from 3 to 20 tons. Their main girder spans the gap between the ground rails and the gantry beam. A trolley hoist moves along the main girder and lifts the load via a hook attached to the hoist. The single-girder design makes these cranes lightweight, easy to operate, and cost-effective. They are ideal for light loads and confined workspaces.

BMG type double girder semi-gantry cranes outperform single girder models by offering greater lifting capacity and a higher lift. They have two main beams that span the gap between the ground rails and the gantry beams. A trolley hoist moves along the length of the main beams and lifts the load via hooks attached to the hoist. Double girder semi gantry cranes handle large loads with ease and offer customization options like lighting, warning devices, and collision avoidance systems.

Semi-gantry Crane Components

A semi-gantry crane consists of several important components, each designed to perform a specific function to ensure smooth and safe operation. The structural diagrams of the BMH and BMG type semi-gantry cranes are shown below:

The main beam uses high-strength steel to deliver high rigidity and strong load-bearing capacity. Its anti-corrosion treatment prolongs service life, and its single-leg design links the opposite side to the factory building, cutting down the footprint and weight.

An electric hoist trolley under the beam enables smooth lifting and precise horizontal movement. Braked rubber tires on the outrigger mechanism ensure smooth travel and accurate positioning. 

The running mechanism employs braked rubber tires to ensure smooth travel and precise positioning along the track.

The electronic control system incorporates a frequency converter and multiple safety devices, securing safe and reliable operation.

المزايا

High Space Utilization: The single-sided support design reduces the number of ground-mounted outriggers, freeing up more usable space in the factory and optimizing factory layout. It is particularly suitable for space-constrained workshops or renovations of existing factories, allowing for flexible installation without large-scale civil engineering.

Wide Coverage and Flexible Layout: Compared to traditional bridge cranes, it covers a wider operating area without the constraints of a fixed track length. Its travel path can be flexibly adjusted to navigate around obstacles within the factory.

Economical and Low-Cost: The simple structure and low material usage result in lower manufacturing costs than full-gantry and bridge cranes; quick installation utilizes existing building structures, reducing installation costs.

Customizable Span and Height: Semi-gantry cranes can be customized to meet different industrial needs. They can satisfy the requirements of large-span workshops or low-level warehouses.

Comprehensive Safety Protection: Equipped with standard safety devices such as movement limit switches and load limits to ensure safe and reliable crane operation and reduce the risk of accidents.

Mechanical Manufacturing Workshops: These semi gantry cranes handle parts and equipment for installation and commissioning. For instance, in machine tool processing workshops, they hoist workpieces and provide both lifting capacity and operational flexibility during the assembly of large mechanical equipment.

Warehousing and Logistics: It enables high-level stacking and rapid lifting of goods. In automated warehouses, it works in conjunction with stacker cranes and conveyors to complete the loading, unloading, and storage of goods. In open-air warehouses or logistics parks, it is used for loading and unloading large goods.

Steel/Sheet Material Handling: In steel mills and processing plants, these cranes are capable of hoisting various steels and plates and efficiently transferring them between production stages.

Construction and Infrastructure Industry: In construction sites and infrastructure projects, it can transport building materials, prefabricated components, and equipment. It can adapt to complex working environments and improve construction efficiency.
