1. What is the feature of double girder gantry crane?

Here are the key features and characteristics of a Double Girder Gantry Crane:

 

Enhanced Lifting Capacity: The double girder configuration allows for higher lifting capacities compared to single girder cranes. These cranes are capable of handling heavier loads, ranging from several tons to several hundred tons.

 

Wide Span: Double girder gantry cranes are designed to cover a wide area or work zone. The span between the two girders can be substantial, enabling the crane to cover larger areas and accommodate wider workspaces.

 

Increased Hook Height: The double girder design provides increased hook height, allowing the crane to lift loads to greater heights. This feature is particularly beneficial in facilities with high ceilings or when lifting loads to elevated positions.

 

Smooth and Precise Operation: Double girder gantry cranes are known for their smooth and precise operation. The presence of two girders ensures improved stability and minimizes swaying or deflection during lifting and movement.

 

Versatile Applications: These cranes are used in a wide range of applications across various industries. They are commonly found in steel plants, shipyards, construction sites, manufacturing facilities, warehouses, and other heavy-duty environments where lifting and moving heavy loads is required.

 

Customizable Features: Double girder gantry cranes can be customized with various features and options to meet specific operational requirements. This includes the addition of auxiliary lifting mechanisms, automation systems, specialized lifting attachments, and safety features.

 

2. Do you use double girder crane indoor or outdoor?
We can use it both indoor and outdoor , if use outdoor under special environment temperature, humidity, need to use special motor.

 

3. What is the maximum capacity of double girder gantry crane?

Usually double girder Gantry Crane maximum can reach up to 100 t. 15 ton gantry crane is more popular.

 

4. How often should lightweight gantry crane be inspected?

Cranes that are used for "normal" or "heavy" provider have to have their periodic inspections carried out yearly. Only cranes in "severe service" are required to be inspected quarterly. A crane that hasn't been used for greater than a month however much less than six months requires all widespread inspections earlier than being used.

 

5. What are the common problems for double girder gantry crane?

1) Parts are deformed, cracked or rotted.

2) Screws or locking nails are loose.

3) Worn, cracked or deformed parts, such as sales, bearings, shafts, gears, rollers, locking and clamping installations.

4) Excessive wear of forklift system components, turning inside, ratchet and ratchet.

 

6. What is CT and LT for gantry crane electric hoist?

In the context of gantry crane electric hoists, "CT" and "LT" are abbreviations that refer to specific types of control systems used for operating the hoist.

 

CT (Cross Travel):

CT, which stands for Cross Travel, refers to the horizontal movement of the electric hoist along the gantry crane's bridge or girder. The CT control system allows the hoist to travel laterally along the bridge, enabling it to reach different areas within the crane's operating range. The CT control typically includes buttons or a pendant station that allows the operator to initiate and control the horizontal movement of the hoist.

 

LT (Long Travel):

LT, which stands for Long Travel, refers to the gantry crane's ability to move along a track or rails in the longitudinal direction. The LT control system enables the crane to travel back and forth along the length of the gantry structure, providing mobility and allowing the crane to cover a wider area. The LT control usually includes buttons or a pendant station to control the crane's longitudinal movement.

 

In summary, CT refers to the control system that governs the horizontal movement of the electric hoist along the bridge or girder, while LT refers to the control system that governs the longitudinal movement of the gantry crane along the track or rails. Both CT and LT controls are essential for the safe and efficient operation of gantry crane electric hoists, providing operators with the ability to position the hoist precisely and transport loads within the desired areas.

 

7. What is the power system for double girder crane?

We usually use Cable reel and uni=pole bus bar line, you can tell us your working current then we recommend you the suitable type power system.

 

8. What are the main factors that influence price?

Several factors can influence the price of a gantry crane. Here are some of the main factors to consider:

 

Lifting Capacity: The lifting capacity of the gantry crane is a significant factor that influences its price. Higher lifting capacities require stronger and more robust components, such as girders, hoists, motors, and structural materials, which can contribute to a higher cost.

 

Span and Size: The span of the gantry crane, which refers to the distance between the legs or support structures, can impact the price. A longer span may require additional materials and structural reinforcements, leading to increased costs. Additionally, larger-sized gantry cranes generally have higher prices due to the need for larger and more substantial components.

 

Customization and Special Features: The inclusion of customized features, specialized attachments, automation systems, advanced control systems, and safety features can significantly affect the price. These additional features require engineering expertise, specialized components, and integration, resulting in higher costs.

 

Manufacturing Standards and Quality: Gantry cranes manufactured to meet specific standards, such as international safety standards or industry-specific regulations, often come at a higher price. Quality components, precision engineering, and robust construction can also impact the cost of the crane.

 

Hoist Type and Specifications: The type and specifications of the electric hoist used in the gantry crane can influence the price. Factors such as lifting capacity, lifting speed, hoist brand, and specialized features (e.g., variable frequency drives) can contribute to variations in price.

 

Installation and Shipping: The cost of installation, transportation, and shipping logistics can add to the overall price of the gantry crane. Factors like crane size, weight, complexity, and the distance to the installation site can affect these costs.

 

Supplier and Brand: The reputation, expertise, and brand value of the gantry crane supplier can impact the price. Established brands with a history of quality products and services often command higher prices.

 

Market Demand and Currency Fluctuations: Market demand and currency fluctuations can also affect the pricing of gantry cranes. Supply and demand dynamics, economic conditions, and currency exchange rates in the manufacturing and purchasing countries can influence the final price.
