Crane Power System: Crane Cables & Cable Drum
Spring Cable Reel & Motorizized Cable Reel

Cable reeling drum for gantry crane, also known as crane cable reel or crane cable drum system is a type of power feeding solution to feed the electricity from the, grid to the gantry crane which can be installed at one end of the operating area or at the center.The gantry crane cable reels are widely used due to the features of small installation space, easy and convenient maintenance, stable & reliable use, and low cost.

Spring cable reels and motorized cable reels are the two main types of gantry crane cable reels which are used to release, retrieve, and store conductor cable for the goliath gantry crane equipment. Our gantry crane cable reels are designed to wind and store flexible cables automatically, with low requirement to maintenance and simple installation, which can be installed stationary, or on a swivel base to enable crane cable to payout in various angles and directions flexibly.

Applications

Crane cable reel and crane cable drum are widely adopted in general use gantry cranes, portal cranes, container gantry cranes and other equipment with similar working conditions to provide power supply, power control or power signal, etc.

The commonly used crane cable reels are usually adopted in the temperature between -20-+40℃, and as for lower and higher temperature, the cold resistance and high temperature resistance crane power line or crane cables should be selected according to the actual application conditions.

Advantages of cable reeling drum for cranes

Crane cable reels may have limited use for standard overhead travelling cranes but offer a perfect electrification method for overhead travelling gantry cranes in tough environments or specialized indoor and outdoor applications.

Crane cable reels can protect crane cable in the corrosive, acidic, or explosive working environments with stainless steel or galvanized steel construction and powder coated components.

Crane cable reeling drums are suitable for demanding applications with high daily duty cycles and crane usage. They are frequently used on the large mobile gantry crane or heavy-duty rail mounted gantry cranes systems.

Main types of crane cable reel

Based on different standards or criteria, the crane cable reels can be grouped into different types, generally, they can be classified into the following types:

According to the driving form of spooling off the crane cable, the cable reeling drum can be sorted into non-electric cable reels and electric driven cable reels.

• The non-electric cable reels also can be grouped into the elastic force or the spring cable reels , heavy hammer cable reels, magnetic coupling cable reels,
• The electron-dynamic cable reels may include magnetic coupling cable reels, torque motor cable reels, hysteresis cable reels and frequency conversion control cable reels , etc.

According to the position of the collector slip ring, it has two forms, the inner slip ring cable reels and outer slip ring cable reels.

According to the arrangement of cables, it can be grouped into the axial single row and axial multiple row cable reels.

According to the winding material, it is divided into cable reeling drum and hose reeling drum.

Spring cable reel for cranes adopts the elastic power of spiral springs to store the cable aromatically. The spring cable reels for cranes are available in three types including slip ring built-in cable reels with compact and delicate contour; slip ring exterior installed cable reels in convenience of service; over hanging cable reels which can coil up longer cables.

Motorized magnetic coupling cable reel

Motorized magnetic couple cable reeling drums are featured as small size, light weight, easy and simple installation and much more, which are widely adopted to deploy and retracting cable in long distance vertically, horizontally and synchronously. The motorized magnetic coupling cable reeling drum are largely used in traveling equipment such as lifting magnet, and electric grab,etc.

Motor-driven cable reel

Motorized cable reeling drum is designed for large specification and in long distance crane cable reeling or releasing which are simultaneously with the crane operation. Based on the power supplying patterns, the motorized cable reels are available with three types including torque motorized cable reels and three phase asynchronous motorized cable reels. Besides, there are specialized motorized cable reels such as motorized cable reels for reeling or releasing power supply cables under 500V and high voltage cables for 6kv and 10kv.

How to select the right cable reeling drum for your gantry crane?

How to select the right type of cable reeling drum for your gantry crane? The selection of the crane cable reels should take considerations of crane cable types and specifications, cable length, crane moving speed, and cable drum installation height, and other factors to meet the demands of the actual working condition of your gantry cranes.

On crane drum designing, it is important to synchronize the winding speed of the crane cable reel and the travelling speed of gantry crane and at same time to ensure the wind tension of the crane cable is moderate to ensure the working life of cable and to prevent cable from loosing and messing up. Accordingly, when you are selecting the right cable reeling drum, the following factors should be considered:

Crane cables types and specifications. What type of crane cables will be used? Round cable or flat cable? What is the section area of crane cable? What is the length of the crane cable? They will affect the selection of cable reeling drum in the following ways:

• Types and sectional area of crane cable .The diameter of crane cable can directly influence the axial dimension of the cable reel and power requirements.The section area of power supply cables are usually from 1.0 to 240mm2. and when it is more than 35 mm2, the non-electric drum may not be a good solution for the counterweight can be extended to 50mm2 and flat cable usually adopts the axial single reel. The types and sectional area of the crane cables can largely affects the selection of crane cable reeling drum.
• Reeling length of crane cable.The reeling length of crane cable can directly affect radial dimension of the cable reeling drum and the power demand. The longer the cable length is, the higher the requirements for power will be. And non-electric cable reeling drum is difficult to accomplish the reeling of cables with large length and in long distance.
• Ground power berth.Ground power berth also directly affect the selection of cable reeling drum, common berth has end power supply and middle power supply. Neutral power supply can't use the non-electric magnetic coupling cable reel.
• The speed of cable reel movement.The travelling speed will affect the motor power of the electric cable reel and transmission ratio.When the speed is more than 60 meters/minute, the frequency conversion control cable reels will be a good option.
• Installation height of cable reeling drum.The installation height of cable reel will affect the motor power of the electric cable reel. The higher the installation height is, the greater the demand for power will be. The installation of cable reeling drum should not exceed the designing requirements.

How to select the right type of cable reeling drum for your gantry crane? The selection of the crane cable reels should take considerations of crane cable types, diameters, cable lengths, moving speed,ground power berth and cable drum installation height, and other factors to meet the demands of the actual working condition of your gantry cranes.
