5 Ton - 32 Ton Double Girder Semi Goliath Crane with Box Girder

Double girder semi goliath crane is a variant of regular goliath crane with one end supported on a leg running on the ground rail and the other end travelling overhead on wall mounted track, therefore also called Single Leg goliath cranes. The single leg semi goliath cranes offers a cost-effective solution for factory or applications with narrow, confined spaces or crowded machinery.

Main parameters of double girder semi-goliath cranes

The semi goliath cranes is a small or middle scale goliath crane, which can maximize your space utilization. With single gantry girder design, the capacity of single girder double girder semi-goliath craneis range from 1 ton to 16 ton, and with double gantry girder design, the capacity of the double girder double girder semi-goliath craneis from 3 ton up to 32 tons.Due to the semi-gantry frame design and semi-overhead crane design, the single legged double girder semi-goliath craneowns the advantages of full goliath crane and overhead cranes, widely used for material handling indoors and outdoors.

Structures & components of double girder semi-goliath cranes

Semi goliath crane is a special form developed on the base of goliath crane. The semi goliath crane has one end of gantry girder,move on an overhead runway system elevated like an overhead crane supported on the building of factory workshop and at the other side of gantry girder is supported on one gantry girder moving on a rail like a standard rail mounted goliath crane.

Main components of double girder semi-goliath cranes

The double girder semi-goliath craneis mainly consisted of the main crane parts and components such as,crane bridge girder , travelling mechanism, trolley part, electrical control system and other electric part,etc. The main crane parts and components such as , hoist, main girder, crane out-trigger or legs, and ground end beam, are presented for your reference. More information about parts and components of double girder semi-goliath cranes, please feel free to contact us.

Electric Hoist :
Dual speed CD1,MD1 wire rope electric hoist, with single girder design & double girder design, can be mounted on single beam & double beam bridge crane, goliath crane and arm cranes.

Main Beam :
Main girder beam is de-rustd by sandblast and painted with zinc rich epoxy primer, and cut by plasma numerical control cutting machine with high precision.

Outrigger :
The rigid outrigger design and flexible outrigger,are all connected by high -tension bolt.
When the length of span is beyond 30m, a flexible leg is need to reduce the lateral thrust of the loaded trolley to the rail.

Ground End Beam :End beam is de-rustd by sandblast and painted with zinc rich epoxy primer, equipted with wheels which is produced in special vacuum casting workshop with more elastic and durable hard-wearing outer surface.

Electric Hoist Trolley or Open Winch Trolley :Dual speed CD1,MD1 wire rope electric hoist, with single girder design & double girder design, can be mounted on single beam & double beam bridge crane, goliath crane and arm cranes.

Main Beam :Main girder beam is de-rustd by sandblast and painted with zinc rich epoxy primer, and cut by plasma numerical control cutting machine with high precision. The ultrasonic or x-ray flaw detection is used to ensure the quality of the butt welding of tension flange.

Outrigger :The rigid outrigger design and flexible outrigger,are all connected by high -tension bolt. When the length of span is beyond 30m, a flexible leg is need to reduce the lateral thrust of the loaded trolley to the rail.

Ground End Beam :End beam is de-rustd by sandblast and painted with zinc rich epoxy primer, equipped with wheels which is produced in special vacuum casting workshop with more elastic and durable hard-wearing outer surface. .

Semi goliath crane, your economical material handling solution

Semi goliath cranes, the special form of overhead goliath cranes combine the advantages of overhead travelling bridge cranes and goliath cranes, but with higher flexibility than overhead eot crane and lower cost than the standard regular rail goliath crane. Semi goliath crane is a good choice to save investment and space, especially when you are in the following conditions:

• Your plant needs an efficient solution to coordinate forklifts to handle heavy or very long loads to improve safety, efficiency and save time.
• Your lifting volume is moderate which does not need to install an expensive and permanent overhead travelling crane system.
• Your plant has existing overhead cranes, but need an economical and versatile lifting system to supplement the existing crane system.

Semi goliath crane has a widely application for various industrial applications, Generally, semi goliath cranes can be used in the following two typical applications:

• Indoors - Semi goliath cranes is used to cooperate with the the existing overhead bridge cranes to provide more hooks and to improve the productivity of your factory.
• Outdoors - The single leg goliath crane is used outside but near the building, , taking advantage of the existing runway structure, to improve the cost efficient of your building.

All in all, Semi goliath cranes offers your economical material handling solution with lifting capacity up to 32 ton and crane span up to 32 m, which is an excellent alternative solution to expensive overhead cranes. Single leg semi goliath crane is widely used for material handling in open warehouse,mechanical processing workshop, outdoor places, etc. However, standard semi goliath crane is not allowed to be in hazardous environments, such as, the environment of combustible, explosive, dusty and corrosive, etc.
