1 Ton Overhead Crane: 1 Ton Single Girder Underslung Crane for Sale

1 ton single girder underslung crane for sale with electric wire rope hoist. An under running crane is typically an underhung single girder crane where the wheels ride or operate on the bottom flange of a runway beam or track. The hoist/trolley wheels will ride on the lower flange of the bridge beam or track. Dongqi manufactures & supplies a wide range of single girder underslung cranes with different configuration as per customer requirements.

Usually suspended from roof trusses, underslung cranes are mainly used for maintenance purposes inside small areas, such as pumping stations and small workshops. Single girder overhead underslung cranes are compact in design and construction, making them ideal for low buildings that require maximum hook height.

Underslung Single Girder Crane Design:

Mechanical parts of underslung crane:

• Single main girder, welding box structure and camber meeting national standards.
• Steel plate material Q235 or Q345B (equals to foreign steel plate Fe3 or Fe52).
• Main welds joint adopts union melt welding, nondestructive inspection.
• After welding, main girder of the underslung crane is through shot blasting treatment, gets Sa2.5 class, and eliminate welding stress.
• Main girder and end girder of the underslung crane adopts bolted connection to ensure strength and accuracy of the whole set.
• Trolley and underslung crane adopt three-trinity driving mechanism, frequency stepless speed regulating, hard-tooth surface, disc brake.
• Crane driving IP55, F class insulation, contact continuity reaches 40% ED.
• Epoxy zin-rich paint, a long service life, beautiful outlook and lustre.
• Crane buffer block, anti-derail end plate.

Electrical parts of underslung crane:

• Safe slide wire: high conductivity, small voltage drop and swift current collector slide speed.
• Lifting mechanism: independent control system for trolley and crane, synchronous and individual operation is possible.
• Electric control box: reasonable layout, simple maintenance and insulation class IP55.
• Underslung Crane Cables: flat cable, galvanized track and cable pulley for trolley traveling power supply.
• Electric contactless module speed regulation controlling.

Protection devices of underslung crane:

• Overload warning.
• Secondary class anti-clamp.
• Sound and light alarm devices.
• Circuit self-check protector.
• Flow phase lack protection, etc.

Underslung crane operation:

• Underslung crane has several operation methods for your selection: ground flashlight door, remoter, flashlight door+remoter, etc.
• Ground operation is simple and professional operator is not required and more freedom is given to the underslung crane operator.
• Double stop button or rocker type joystick.
• Customized operation design for the underslung crane is available.

Underslung Single Girder Crane Design Features:

• Ceiling supported runway system for under running cranes will maximize usable floor space.
• Most commonly used in light to medium duty cycle applications.
• Can have longer crane spans with 2, 3 or even 4 runway beams to support the under running crane system.
• Interlock into a monorail or spur rail with an under running crane systems.
• Under running cranes are most commonly used in assembly plants, fabrication shops, maintenance areas and manufacturing facilities.
• Underslung cranes with single girder is installed taking support of roof structure and is ideal to be used for minimized loading applications. It is completely suitable to be utilized in warehouses, industries, dockyards, automotive, aerospace, and architectural industries.

Dongqi Overhead Underslung Crane Advantages:

• Good quality with competitive price.
• Reasonable structure, favorable performance.
• Easy to use, operate and maintain.
• Control the load easily and position the load exactly.
• Smooth starting and stopping.
• Superior safety and reliability.
• Low noise, commodious cabin and good view.
• Low dead weight low your cost.
• Easy maintenance for parts.
• Longer serving life.

Underslung Single Girder Crane Unique Attributes:

• Optimum design of the structure avoiding dead weight and reducing the cost of the equipment.
• Very much suitable for power house cranes where these cranes are used for maintenance.
• Economical Design by providing manual long and cross travel facility with a provision for using either an electric hoist or a motorized chain pulley block.
• Low head room which in turn reduces the cost of the shed/building.
• Customized design to match the budget of the customer.
• Highly Competitive Prices.

Difference between Top Running and Underslung overhead crane:

• Support structure: Underslung cranes can be suspended directly from the roof structure or other overhead beam. top running cranes need independent columns to support the end trucks and the bridge beam.
• Capacity: As underslung cranes are suspended from the roof structure, they are available only on lighter capacities, usually less than 16 tons. The capacities of top running overhead cranes are much larger. The safe working load of top running cranes can even up to 500 ton.
• Configuration: Because of the light capacity, underslung cranes usually adopt the single girder configuration, although double girder under running crane is also available in some special cases. But the top running overhead crane equipped with double girder is more frequent.
• Utilization of space. Something unique to underslung cranes is their ability to make full use of the available height and the tight space. They can ensure efficient material handling even in plant where very little space is available.

How to Buy Underslung Crane?

To install an underslung crane, the roof structure must have the ability to withstand the weight that imposed by the underslung cranes itself and the load.
