Different Loads Of Electric Hoist Need to select a suitable diameter for the rope,but do you know how to select it ? now,lets try wroking with HMIC on it together.
Currently,the Wire rope electric hoist is one of the most popular products in the area of small and light lifting equipment, due to its strong load capacity and efficiency.
People who understand the working principle of the hositshould known that its main traction part for the wire rope, compare with the traditional lifting chain, the wire rope can runningmore smoothly,no needworry much about the occurrence of the chain situation.
Each electric hoist wire rope specifications are not uniform, as it was selectedbased on the rated lifting capacity of thehoist, to determine the mutual matching specifications will inevitably make the wire rope diameter will increasing.
This processcan ensure the safety of crane or hoistlifting operations, but do you know how to judge or select a suitable wire rope diameter for your crane or hosit ?
For the rated load capacity of thewire rope electric hoist can be mainly divided into 1 ton, 2 tons, 3 tons, 5 tons, 10 tons, 20 tons.and for the diameter of the rope for each capacity can be reference as the following data: 7.7mm, 11mm, 13mm, 15mm, 17.5mm, 19.5mm.for some big tonage such as over 30 tons, the rope diameter can selected based on the rerquiment of the lifting capacity. we can simple judge like our crane /hoisting over load limiter's working range as a reference:BMK Series crane over load sensore from HMIC. range from0.5Ton- 32Ton. That isthere also have small tonage such as0.5 tons wire rope electric hoistwith thewire rope specifications of 4.76mm or 5mm. these data are after rigorous scientific data analysis, but also the best state in lifting operations.
As can be seen, the decision to use which diameter for thewire rope electric hoist is not only the formal operation, maintenance and other issues, wire rope and electric hoist match process arealso plays an important factor for the lifting safety.so please kindly remind everyone, when your electric hoist needs to replace the accessories wire rope, Makesure to understand it matches the correctwire rope specifications and also select qualified and reliable supplierto prevent fail work and make your lifting working safety.
Rope diameter selecting reference data from HMIC :
| Load capacity(Tonage) | Ratio/Crane rope number | Wire Rope Diameter |
| 0.5 Ton | For this need based on the design of the lifiting. but ratio of the crane really important factor for select suitable rope diameter . please need pay attention to it.
For the capacity, indeed it can be from 0.5 Ton to 32 Ton, here,we make a reference to max 20 Ton as your reference.
The rope diameter selecting habit are based on China crane standard or normal habit. please reference.
| 4.76/5mm |
| 1 Ton | 7.7mm |
| 2 Ton | 11mm |
| 3 Ton | 13mm |
| 5 Ton | 15mm |
| 10 Ton | 17.5mm |
| 20 Ton | 19.5mm |
| More big Tonage.... |
