chain hoists «

Hoist UK is pleased to announce the formal international launch of the Concerto series of Variable Speed Concert Hoists from Niscon Inc.

The Concerto has been designed and engineered using a Stagemaker^® hoist body and with the support and assistance of R&M Materials Handling of Springfield, Ohio, and Verlinde SA, France.

The Concerto is conceivably the most concise and safety conscious variable speed chain hoist on the market, meeting and exceeding some of the worlds strictest legislation for chain hoists both in Europe and the Americas.

In addition to the usual heightened design factor of safety and double brakes required in this type of hoist there are two sets of safety limits each with independent functionality and different activation methods (one rotary and the other direct struck) to prevent accidental over-travel of the hoist.  The rotary switch is monitored for rotation using an encoder which also functions as the backup to the main encoder.

A third encoder is attached to the load wheel to ensure the chain has travelled to its exact position.  The values from each encoder are constantly compared against the others for errors with encoder data stored and saved even when the power is turned off to the hoist.

Niscon Inc.’s president, Joseph Jeremy says, “This hoist is simply the best I have seen on the market.  In comparison to other chain products, the Stagemaker^® body was the only choice that could deliver the performance we were looking for along with consistency and accuracy throughout the manufacturing process. Our goal was to develop a variable speed chain hoist that was safe, practical and would complement the Raynok line of motion control solutions.  In order to achieve this we added additional features to enhance safety and performance of the overall product, including a rotary limit switch, load cell and not one, but three encoders.”

The first public showing took place at the PLASA 2010 trade show in London, on the Hoist UK stand forming part of the central display which also showcased the Raynok motion control system. “I have been working with chain hoists and control in the entertainment industry for the last 18 years and have been involved with several motion control systems in the development stage, touring and in fixed installation applications.

The combination of Raynok motion control system and the Concerto hoist is by far the most precise, intuitive and safest system I have ever used” comments Hoist UK’s director Tony Dickson. “The Concerto is smooth, quiet and infinitely versatile and a great addition to our repertoire, it will be loved by riggers and LD’s alike” adds Hoist UK’s fellow director Paul Jordan.

An early version of the hoist can be seen in performance at Haze Nightclub at Aria in Las Vegas where Niscon Inc. installed 20 units for John Lyons Systems of Los Angeles, California.  The Haze system uses 20 hoists to manoeuvre 5 lighting trusses over the dance floor to enhance the effects of the light show for the club’s guests and patrons.

Niscon Inc.’s VP, Peter Sinkner says of the Haze installation, “John Lyons wanted smooth fluid motion on the Haze dance floor.  He wanted to give the patrons something different and really WOW them.  On his first visit to the club, John asked me to show him what the system could do.  I took control of one of the trusses with the Raynok MK2 Console joystick and rolled the truss on pitch and yaw while also flying it up and down.  When I stopped and looked at John, the smile on his face said it all.  Niscon Inc. had delivered what he was looking for and then some.”
