What is Single beam gantry crane

1. Single beam gantry crane is a general-purpose crane, which is mostly used for loading, unloading or grasping materials in open places and warehouses. Our products have two forms of ground operation and indoor operation. There is no external revolving gantry crane in the box, which is used together with the hoist. It adopts steel pipe legs and small windward area. It is the best light door crane in open places and windy areas. There are two operation modes: free operation and ground operation. The lifting capacity is GN = 2-32t, the span is 10-35m, the ambient temperature is below + 40 ℃, the working system is 25%, and the wind pressure is not greater than 125pa

2. Technical features: three in one transmission system, electrical contactless module speed regulation control, and can realize micro speed and two speed proximity frequency conversion function, so that the operation, lifting and electric are particularly stable. It is equipped with overload alarm, skew hoisting, secondary protection against hook punching, missing item overcurrent protection, etc. the console (handle) adopts 12V safety voltage, so as to realize the multi-functional protection of hoist single beam. When the voltage is within 380V + 5 ~ – 10%, the electric control can be used for 2 million times for a long time.

3. Selection principle: use industry, start, jog times / 1H. Practical time per day. It must be noted that the inching and starting of light crane are GN / 10 ≈ 80 times / 1H, GN / 2 ≈ 40 times / 1H, GN / 1 ≈ 15-20 times / 1H, high temperature 50 ℃ and harsh environment times / 1H ÷ 2 (indicated when the altitude is more than 800m).

4. Precautions: 1. When the crane stops working at the operation site, the user shall lock the crane in time. 2. There is no wire above the main switch of the crane. It is strictly prohibited to lift high-temperature solution, flammable, explosive, corrosive (acid, alkali, plating, steaming moisture), overload, dust and other dangerous operations. 3. The total length of the external suspension of the gantry crane is less than 1 / 3 of the mid span, and 90% of GN at the external suspension limit. The crane can run only when the heavy object is moved to the inside of the leg. The weight gn of the crane running outside the leg shall be reduced by 10-20%. When the external suspension exceeds one third of the middle of the span, GN shall be reduced by sections. Under the above conditions, the heavy objects must be close to the outrigger crane before operation, and the small span should not be operated outside the leg.

Single beam gantry crane with L shaped leg

L model single beam gantry crane is matched with trolley, a kind of track travelling mid-light type crane. It is ideal for outdoor applications where lifting facilities are provided without the cost of a building or any supporting steelwork. They are also suited to indoor applications where existing building structures are not suitable to take overhead cranes, and where additional supporting steelwork would result in a loss of floor area. It can be constructed with a cantilever to allow handling outside the rail centers.

Main parameters of the single beam gantry crane

• Lifting capacity: 5~50t
• Span length: 18~35m
• Lifting height: 6~12m
• Working class: A4, A5
• Ambient temperature: -20~40℃

What are the risk factors and preventive measures of single beam hook gantry crane

The gantry crane starts running

1.  Attention shall be paid to whether there are people or objects in the track accessories
2.  When the crane is running, people cannot stand or pass under the beam or cantilever
3.  The lifted heavy objects shall not be over the head to prevent the heavy objects from falling suddenly.

Precautions:

1.  Install alarms at both ends of the ground beam of the gantry crane. When the gantry crane is running, alarm first. Install infrared limiters or other limit sensors at both ends of the ground beam to stop people or objects automatically
2.  Strictly implement the operating procedures for special equipment management,
