Therefore, our gantry crane with European hoist has entered into Ethiopia market.
Gantry crane specification plays a vital role in installing and maintaining the crane, and the gantry crane’s service life is likely to be extended by complying with the crane specifications strictly.
1. Product Description
Different from bridge crane, gantry crane achieves its lifting work by supporting several legs on the ground, which is free from the limitation of plants. Consisting of main frame, cab, trolley travelling system, crane travel equipment, electric control system, etc. gantry crane system is of large span and large lifting capacity.
2. Main Application
This kind of product is widely used in different kinds of places such as rail-way lines, warehouses, docks, material yards, shipyards, container ports, etc. Nowadays, it has been regarded to be the necessary machinery equipment of improving the labor conditions and efficiency.
It mainly used with different types of electric hoists or lifting hook for general lifting purposes, if it is necessary to use in other special environment, please contact Ellsen Company, we can provide best solution to you.
Hoisting mechanism mainly consists of driving device, wire rope coiling system, loading device, and safety protection devices. Among this, driving device contains electric motor, gear reducer, brakes, group reel, and couplings, which drives the whole machine operating.
Trolley Travel Mechanisms
Travelling mechanism drives the trolley move, generally, it is mainly featured of low speed shaft.
Frame gantry is composed of main beam, end beam, bottom crossbeam, supporting legs, trolley track, platform, handrail, cab, and stepladder, etc. They are made up of the basic foundation of one gantry crane.
· Main Beam: Generally, applying Q235B model material of the beam is for the purpose of staying rigidity and stability.
· End Beam, the main beam and end beam is connected by high-strength bolt to ensure its safety, every bolt is marked before delivery.
· Supporting Leg: Adopting the rigid leg and flexible leg when the span length of the crane exceeded to 35 meters, it can improve the flexibility and affordability of the whole set.
· Bottom Crossbeam: To increase the carrying capacity of the crane, it is connected by high strength bolt to protect the crane’s stability.
· Cab: the arrangement of cab’s setting are fully considered of operator’s safety, easy-operating and maintenance.
Crane Travelling Equipment
· The crane gantry achieves its separating travel by the supporting of wheels。
· The structure of crane’s driving mechanism is convenient to the installation, maintenance and disassembling.
Electrical Control System
· Three-phase voltage or customized by the clients’ demand.
· Power supply mode: sliding cable lines, cable reels, or diesel generation.
· The circuit structure for the function of out-voltage protection.
The operator must install the crane with its qualified license.
Practical setup project should be scheduled before installation.
Debugging the machine after installing the crane, rectify and debug until it come up to the national standard.
Inspection and acceptance of the structure, basic dimension of the crane at buyer’s site.
Testing loading capacity after installation and debugging, going approval rating and filling in the inspection report.
7. Safe Operation
The qualified operators should operate the gantry crane according to the safe specifications strictly in order to protect the crane safety.
8. Equipment Maintenance
Carrying out routine maintenance according to maintenance plan, ensuring the crane is in line with safety requirements.
Besides, Ellsen Company can help the customer do crane repair if it is necessary.
What is a gantry crane? Speaking of gantry crane definition, as the deformation of the overhead cranes, it is a gantry lifting equipment that used in different working occasions, such as container port, shipyards, dock, offshore, etc. For its appearance and structure looks like a portal or a gate, it has been called gantry crane.
The Basic Component and Structure of a Gantry-crane
What is a gantry? A crane gantry mainly consists of bridge, supporting legs, electric control system, crane travelling system, trolley travel mechanism, lifting organ, cab, etc.
1. Basic Frame of A Gantry Crane
The basic frame of gantries such as main beam and supporting legs are composed of box-shaped or truss structure. Different structures are of their own advantages. Box-shaped crane is for the advantages of strong-rigidity and easy-maintenance, while the truss-shaped structure is of strong wind-resistance ability but light lifting capacity.
2. Electric Control System
Electric control system in gantry mainly refers to gear reducer, brakes, electric motor, etc. The three of them controls the travelling of the trolley machines and cranes.
3. Crane and Trolley Travelling Systems
Crane travelling system and trolley travel mechanisms can achieve running once energized. And there are three power supply mode of gantries, cable reels supply, diesel generators and sliding wires supply.
Ellsen Group adopts to advanced level wheels in the crane. All wheels are of compact structure and smooth moving, which ensure the smooth operation and high-safety of the whole set.
4. The Settings on Cab
Ground operation and air operation are two forms of gentry crane. In order to decrease the labor intensity and guarantee safety of the operators, it is necessary to build a cab on the crane, besides, operators control in the cab can also increase the accuracy of the goods and materials handling.
Gantry Crane Features and Advantages
1. Widely used in outdoor and indoor places for material handling works.
2. Compared with overhead crane, granty crane is of low demand on the plants.
3. Once exceed to 30 meters in span length, flexible leg and rigid leg need to be set to improve the safety of gantries.
4. Ground sill is required in heavy-duty gantry cranes.
5. Cantilever cranes need to be used with saddle to improve safety.
Ellsen Gantry Innovation＆Breakthrough in Technics
1. Ellsen electric control system adopts to the advanced lever ABM three-in-one or SEW three-in-one motor, which proves the integration of gear reducer, brakes and electric motor.
2. Advanced buffer and intelligent overhead limiter ensure safety operation.
3. First-class emergency shutdown system in Ellsen Grantry crane.
4. Guard net in trolley travelling mechanism to protect safety.
5. European type crane and electric hoist can be matched to enhance working efficiency and extend lifetime services.
