Spring cable reels

Mobile and movable equipment depend on a flexible power supply. Many applications also require the transmission of data signals or the supply of compressed air, hydraulic fluids and gases. To prevent the cables and hoses from being damaged and endangering operation, they must be automatically wound and unwound. The cable can be taken off horizontally or vertically on the left or right side.

Funktioner

1. High plant availability
2. Travel speeds up to 60 m/min
3. Up to 120,000 spring cycles are possible
4. IP55 protected, higher classes available on request
5. Suitable for ambient temperatures from -20 to +40°C
6. Use in harsh environments possible

Chain cables

TLG-type steel drag chains can carry a large number of overhead crane cables and oil pipes with large weight. This type of overhead crane cables is freely suspended (allowing the use of support wheels) and has a large length. The support plate can be made according to customer needs. It is suitable for work mother machines, mobile machinery, etc. Its bending radius is 50-600mm, and the height of the chain plate is 35-150mm, which can be selected arbitrarily.

Funktioner

1. The TLG-A steel drag chain has a stroke of 32 meters.
2. Suitable for all transmission methods.
3. Can be lengthened and shortened at will.
4. The bending radius can be changed by changing the pin shaft.
5. The width of the support plate of the drag chain is 150mm to 600mm, and the interval between the holes is 5mm.
6. The height of the chain plate, that is, the height of the support plate, is determined by the large diameter of the cable. When the machine tool is operating to the maximum extent, if the width of the tow chain exceeds 300mm, and the length of the tow chain exceeds 4m, for stability reasons, you should consider choosing a tow chain that increases the size of the No. 1 specification.
7. The bending radius should be selected according to the large diameter of the cable and should reach 10 times the diameter of the cable. The bending radius can be selected from 50-600mm according to the table given, and the smaller radius can be selected accordingly for small strokes.
8. The length of the drag chain = 1/2 stroke + 4 bending radii, which is only applicable when the fixed connection is at the midpoint of the stroke.
9. The fixation of the drag chain can be selected according to the position of the machine tool. The fixed angle steel can be placed on the periphery or the inner periphery in or outside the drag chain. Under normal circumstances, the connecting part is in the drag chain and to the periphery.

Large festoon systems, cable festoon systems for T-beams

In concrete and steel plants, crane systems are often stretched to their limits. Container gantry cranes in large ports, whose trolleys alone weigh several times as much as a small car, are also subjected to extreme loads every day.

A reliable power supply is essential to ensure that the hoists can perform their tasks day in, day out. As a rule, festoon systems are used for this purpose.

Large festoon systems are manufactured individually for the respective requirement. The scalable systems can accommodate round or flat power and data cables.

The trolley and roller characteristics are always aligned with the carrier system available on site and the speeds travelled. This ensures safe and smooth system operation.

This type of overhead crane cables can be supplied pre-assembled to reduce on-site installation work to a minimum. The use of high-quality materials also ensures high resistance – even to environmental influences such as salty or humid air. At the same time, this reduces the amount of maintenance required, which noticeably increases system availability.

Funktioner

1. Carrying capacity of the trolleys: max. of 35 kg
2. Speeds up to 60 m/min.
3. Curved tracks are only possible with this system.

Small festoon systems, cable festoon systems with C-rail

C-type rail cable trolley is an ideal logistics power supply system, suitable for indoor and outdoor, dusty, and large temperature differences. At present, cable carts are widely used in the mobile power supply of various general-purpose bridge cranes, gantry cranes, electric hoist carts, warehouses, shipyards, docks and other lifting equipment.

Funktioner

1. Low environmental requirements；
2. Running smoothly；
3. Low failure rate；
4. Applicable for flat wire and round wire；
5. Equipped with a buffer device and a cable protection device.

Angle steel flat cable trolley for festoon system

The angle steel flat cable trolley for the festoon system is a new product overhead crane cables that replace wire rope pulleys and C-shaped steel slide pulleys. This type of overhead crane cables have the characteristics of flexibility, tensile resistance, wear resistance, and long service life. Overhead Crane Cables have many advantages such as reasonable structural force, durability, suitability for high-speed operation, and simple installation.

This type of overhead crane cables solves the troubles of wire rope pulleys that often break cables and C-shaped steel card slots, and has a small operating size.(For example: a 10-ton-28.5-meter single-girder crane needs to install 14, and the total length of the angle steel pulley gathered at one end is only 56cm). Due to the reasonable force structure, the angle steel pulley runs extremely smoothly.

This type of overhead crane cables is the choice of electric hoist as the power supply device. Angle steel cable pulleys are mainly used for electric single-beam bridge cranes, electric hoist gantry cranes, and electric hoist power supply cable pulleys for electric hoist gantry cranes. Angle iron hanging cable carts for cranes are divided into two types: round cables and flat cables.

Funktioner

1. Easy to use and free rotation: It can rotate at any angle, easily removing the rotational force generated during hoisting, making it more convenient to use.
2. Thickened materials
3. Bearing rollers, metal bearing pulleys, smooth sliding
4. Galvanized anti-rust
5. It has a reasonable structural force, is durable, and is suitable for high-speed operation.
6. And many advantages such as simple installation.
