Question 1

What is a semi gantry crane?

Accepted Answer

A semi gantry crane is a lifting system with one side supported by an elevated runway and the other side supported by a floor-running leg. It combines the advantages of an overhead crane and a gantry crane, making it suitable for workshops with limited space or existing runway structures.

Question 2

What is the difference between a semi gantry crane and a full gantry crane?

Accepted Answer

A full gantry crane has supporting legs on both sides and normally runs on ground rails. A semi gantry crane has one floor-running leg while the opposite side operates on an elevated runway. This design can save floor space and make better use of an existing workshop structure.

Question 3

What lifting capacities are available for semi gantry cranes?

Accepted Answer

The lifting capacity can be customized according to the customer's requirements. Different configurations can be designed for light, medium or heavy-duty applications. Please provide your maximum load and working conditions so we can recommend a suitable capacity.

Question 4

Can the semi gantry crane be customized for my workshop?

Accepted Answer

Yes. The crane can be customized according to your workshop dimensions, lifting capacity, span, lifting height, running length, power supply, working class and control method. We can develop the configuration based on your actual working area.

Question 5

Does the customer need to prepare the floor rails?

Accepted Answer

The required floor rail system can be supplied as part of the crane solution. Rail specifications and gauge should be determined according to crane capacity, wheel loads, running conditions and workshop layout.

Question 6

Can a semi gantry crane work in an existing factory?

Accepted Answer

Yes. One of the major advantages of a semi gantry crane is its adaptability to existing workshops. It can be designed around existing building structures and available floor space, subject to checking the runway, foundation and rail conditions.

Question 7

How do I choose the correct crane span?

Accepted Answer

The required span depends on the distance between the crane supporting points and the working area that needs to be covered. Customers can provide workshop drawings or the relevant dimensions, and our engineers can help determine a suitable crane span.

Question 8

How do I determine the required lifting height?

Accepted Answer

The lifting height should be based on the highest position the load needs to reach and the available headroom inside the workshop. We recommend providing the required hook height, building height and working clearance for accurate design.

Question 9

What power supply does the crane require?

Accepted Answer

The power supply can be customized according to the installation location. Voltage, frequency and phase should be confirmed before production. Common industrial power configurations can be accommodated according to the customer's local electrical standard.

Question 10

Is the semi gantry crane suitable for outdoor use?

Accepted Answer

Yes, the crane can be designed for outdoor applications when required. For outdoor installation, factors such as weather conditions, wind load, rain protection, corrosion protection and electrical enclosure requirements should be considered during engineering.

Question 11

What safety devices can be installed?

Accepted Answer

Depending on the application, the crane can be equipped with overload protection, emergency stop, lifting and travelling limit switches, motor protection, warning alarms and other safety devices. The configuration can be adjusted according to the working environment and applicable requirements.

Question 12

What type of hoist is used on a semi gantry crane?

Accepted Answer

The crane can be configured with a suitable electric hoist according to lifting capacity, lifting height, working class and operating frequency. Electric wire rope hoists are commonly used for medium- and heavy-duty material handling applications.

Question 13

Can the crane lift steel plates and heavy steel structures?

Accepted Answer

Yes. Semi gantry cranes are widely applicable to steel fabrication and metalworking environments. They can be configured for handling steel plates, profiles, fabricated structures, machinery components, molds and other heavy loads.

Question 14

How difficult is installation after the crane arrives?

Accepted Answer

Installation requirements depend on the crane configuration and site conditions. We can provide installation drawings, technical documents and assembly instructions. For larger projects, installation guidance or technical support can also be discussed before shipment.

Question 15

How can I get a customized semi gantry crane quotation?

Accepted Answer

Simply send us your basic requirements, workshop drawing or available dimensions. Our engineers can evaluate the working conditions and recommend a suitable semi gantry crane configuration. We can then prepare a customized technical proposal and quotation based on your project requirements.
