Safety should never ever be compromised when it comes to lifting, but when it comes to lifting in areas where the load is positioned over members of the public’s heads then safety is a majorly high priority. Lifting regulations state that hoists must be rated to perform lifts above people to ensure the loads could not fall and cause the un-thinkable. These hoists maybe far from cheap but what really are you getting for your money? Probably not a lot more than a few modifications to the slipping clutch etc. and re-assurance to the mind, this can be in some peoples eyes a waste of money, but without using the correct hoist you are breaking the law and if the load/ hoist lands on someones head then the responsibility lands on yours, and this is never something you want to deal with.
The Verlinde Stagemaker inverted (upside down) hoists where the motor is hooked to the load and the hoist climbs the load chain in order to reach its highest point, this hoist is said to be a great piece of kit and it can be controlled in a number of ways such as direct control or low voltage control using external control units or via low voltage pendant controls sometimes referred to as a pickle.
All in all if you are operating loads over heads of people then the correct equipment should be used, you should never take the risk of using equipment that is not rated for the purpose of application. To find out more on electric chain hoists visit Lifting Equipment Store.
As an entertainment rigger of 30+ years I agree completely. I have been to and certified to work on CM, Stagemaker, and ChainMaster hoists. We have 1200 ChainMaster in our inventory and go thru them every time they go out and return. Safety is always the primary concern.
I believe that CM requires the motors to be tested and certified annually, correct?
Yes correct, like most brands.
