Electric hoist basics:Difference of CD wire rope hoist and ND wire rope hoist

By seeing this title you must be very confused what we will show, what is the CD type wire rope hoist and ND type wire rope hoist, why we say the CD type and ND type wire rope hoist’ differences? Actually, CD type wire rope hoist is the type of traditional wire rope hoist and ND hoist is the type of European standard wire rope hoist.

For the reason why I want to tell you their differences is that recently I received my customer’s question:

“Dear Latty,

Thanks for your prompt reply.

I´m sorry for doing so many questions, but we have no experience in electric hoists trolleys, and we don´t want to make a mistake with this product because it would be dangerous for the safety of our workers.

Could you send me information and price of the 2 ton european model and kindly tell me what´s the difference between the model CD2T-9m that you have quoted and the model ND European Electric Hoist? Advantadges and disadvantadge.

We also need you to suggest us what spare parts should we order for 3 working years.

I´ll be waiting for your reply.

After receiving my customer’ questions I know that our customers who need the products but they may not the professional one at the crane and hoist market. They have their confusions so I make a simple comparison for their reference. And if you also have this confusion, please see the blow clarifications and may this can help you.

Firstly, let’s see the wire rope hoist appearance:

CD type wire rope hoist

ND type wire rope hoist

Secondly, let’s see the CD type and ND type wire rope hoist technical comparison, we will take the 2ton-9m specification as example:

From the technical specification, we can see that:

• For the speed, ND type is frequency conversion and CD is only single speed. ND type hoist has a converter which can make the hoist traveling and lifting more smooth and less noise.
• For the working class the ND is M5, CD is M3 which means that the ND hoist can keep working about 12 hours, CD hoist can keep working 8 hours. You can choose the hoist according to your working condition.
• For the configuration, ND hoist uses the Germany brand ABM motor and French brand Schneider electrics which cost is much higher that CD hoist as CD hoist uses the Chinese famous Nanjing special motor and Chint brand electrics. Both of them are good quality but the CD hoist has highly cost effective.
• For the motor power, ND type hoist’s power is higher than CD type.
• For the total weight, ND type hoist’s weight is heavier than CD type as its special design.
• For the appearance design, ND type is more elegant than CD type.
• For the maintenance, ND type has low failure rate and the quality is higher than CD hoist.

In Conclusion, ND type wire rope hoist has the best quality with the high price and CD hoist has the general quality but with the low price. If you consider about the quality and maintenance ND type hoist is a good choice but if you consider about the cost effective, CD type hoist is a better choice.

Now do you have a simple understanding about these two hoists?
