FAQ (Frequently asked questions)
Nominal load describes the load that the rope winch is capable of carrying in the first, that is, the lowest rope layer. The actual load diminishes with every additional rope layer in relation to drum diameter. (see diagram)
2 Does the rope speed change while coiling up/ unwinding the rope?
For the first rope layer it doesn’t, of course. Rope speed increases with every additional rope layer in relation to drum diameter. (see diagram)
3 What about rope capacity?
Rope capacity does not increase linear to the number of layers, so for example a drum with 3 layers can hold more than 3 times the storage of the first layer.
4 Why do you use a grooved drum?
A grooved drum improves proper coiling (passively).
5 What does a pressure roller do?
A pressure roller prevents the coiled up rope from uncoiling violently.
6 In which cases would I use a traversing unit?
Using a traversing unit means being able to actively guide the rope, which again improves proper coiling, especially that of big rope drums and heavy ropes.
7 What’s the difference between winches according to DGUV 54 and those according to DGUV 17?
DGUV 17 winches have a permission to be used on stages and for scenic performances.
haacon delivers DGUV 54 as standard. Winches according to DGUV 17 deliver as well.
8 Does haacon supply winches according to ATEX norms?
No, it doesn't.
9 Are haacon electric rope winches suitable for passenger transport?
No, the standard winches are not authorised for passenger transport. haacon however may also deliver so-called "Man-Riding" winches.
10 What is the difference between lifting winches and pulling winches?
Pulling winches are exclusively for pulling loads horizontally.
Lifting winches have to be equipped with a limit switch.
11 Why is it that at least two layers have to remain on the drum at any time?
All the rope clamp does is fixate the end of the rope when mounting the rope. The necessary holding force is generated by the two mounted rope layers.
12 Is a rope included in delivery?
No, the rope is not included in delivery, however may be delivered as accessory. Unless agreed otherwise, ropes are delivered lose.
13 Which safety class is right for my purposes?
Please see table of safety classes below.
14 In which cases do I need overload protection?
According to the safety regulation on winches, you need overload protection for nominal loads exceeding 1000 kg.
15 When would I use a slack rope device?
A slack rope device is needed for loads that can cause blockage during downward movement (guided loads).
16 Which control voltage does haacon use?
Control voltage of 230 V is standard, a version of protective low voltage (24 V DC) is available.
17 Can I get electric rope winches ready to plug?
No, this is not possible as it contradicts relevant safety regulations.
18 Does haacon use pole-changing motors?
No, haacon equips its electric rope winches with frequency converters.
19 Why do you use frequency converters?
They offer more benefits:
- Continuously variable or multi-stage speed control
- Integrated overload protection
- Smooth starting
- Unrestricted usability for 230 and 400 V supplies
20 In which cases would I use 230 V or 400 V motors respectively?
400 V motor is the best possible option concerning technics.
We recommend a 230 V motor if the winch is used for mobile applications or if there is only 230 V supply available.
21 Cable pendant remote control with direct or indirect control?
In direct control, the drive of the motor is carried out directly by the cable pendant remote control. This version is simple and low-priced if options like limit switch, engine protection or overload protection are not required.
For indirect control, you have the option of whether you want overload protection or not. It always includes engine protection and is therefore prepared for all options (limit switch). It is thus possible to retrofit existing winches.
