I. Principle and Characteristics:
The working principle is similar to that of steel tape measure, using the coil spring as the power to rewind the cable. When the cable is pulled out, the coil spring is tightened. When the external force is withdrawn, the coil will automatically rewind the cable by using the energy stored by the coil spring, with good synchronization performance.
Two, model description:
Three, selection guidance:
1, spring type cable reel voltage range: below 500V;
2. Classification of spring type cable reel:
① According to the installation mode
A: vertical take-up B: Horizontal take-up (roll moving)
F: suspended take-up C: horizontal take-up (fixed reel)
② According to the length of the cable, it is divided into three series of 15, 20 and 25m;
(3) Design special types according to user needs:
A. Speed up type (reel length up to 50~60 meters), used in electric flat car CLQ-I reel inconvenient installation conditions;
B. Multi-cable type: one reel reel 2 cables of different specifications;
C. Cable type: the cable for transporting water, steam, oil and other media;
3. The length of cable provided by the user for the reel is about: L+ 2 loops are reserved for the reel.
4. The directions of cable collecting and laying on the drum have been indicated in the scheme size drawing. If you have special requirements, please explain when ordering.
5. If the cable reel needs to be installed in the single beam truck and electric hoist, please explain the single beam steel specification used when ordering, so as to prepare the corresponding roller support parts for convenient installation and use.
Applicable to cables, equipment and working conditions
Suitable for the horizontal and vertical retracting of power supply cables and multi-core control cables below 35 mm2, such as lifting electromagnet sucker, grab , electric flat car and other equipment and similar working conditions.
Five, the size of the structure: the following are several common types for users' reference, can be based on the user of a variety of different working parameters scheme
Design, tailored to meet the needs of users.
