The PowerLine provides a wide range of speeds and capacities, making it a versatile performer. Applications include scenery, lighting sets, curtains, and front-of-house lighting. These hoists have minimal side loading on the building structure, simplifying building steel and making these hoists excellent for retrofits in older buildings. Learn more about the PowerLine Line Shaft Hoist by downloading the spec sheet.

StageHand

StageHand you get extraordinary lifting capacity for an economical price.  Manual utility hoists for access to lighting sets, masking curtains, and other items that do not move as part of a performance. The hoist can be padlocked for security. The StageHand hoist shall not be used to lift humans. Learn more about the StageHand Hoist by downloading the spec sheet.

 

StageHand+

StageHand+ you get extraordinary lifting capacity for an economical price. A motorized utility hoists for access to lighting sets, masking curtains, and other items that do not move as part of a performance all at the push of a button. The hoist can be padlocked for security. The StageHand hoist shall not be used to lift humans. Learn more about the StageHand Hoist by downloading the spec sheet.

 

Titan

Clancy has been building big, custom performance hoists for many years. The Titan hoist is a semi-custom hoist providing high speed and high capacity in a compact package.  These performance hoists are used in major performing arts centers, opera houses, and concert halls.

Two Rigging Draft Standards Up for Review from ESTA

Looks like ESTA has just announced the release of two drafts of rigging standards for review to the industry. If you have any interest or knowledge of rigging, you are encouraged to provide your valuable input into the drafts.

With any review of draft standards, there is a limited time that the public are allowed to review and comment on the standards.  These two particular draft end review on February 15, 2010.

Here is more about the two drafts that are up for review:

BSR E1.6-2–201x, Entertainment Technology — Design, Inspection, and Maintenance of Serially Manufactured Electric Chain Hoists for the Entertainment Industry

BSR E1.6-1–201x, Entertainment Technology – Powered Hoist Systems

You can download and review these documents at the Technical Standards Program page found on the ESTA web site, www.esta.org.

JR Clancy Introduces New SureBrake II on PowerLifts

We recived a Press Release from JR Clancy that they have developed a new Braking System for the PoweLift hoist system, SureBrake II.  The SureBrake II increases the safety and reliability by having a faster acting load brake to catch any failure before a batten becomes a runaway.

Read more from The Press Release:

PowerLifts have a dual braking system – the primary brake is on the motor, and stops the motor at the end of a move. The load brake is a redundant brake acting on the drum shaft for added safety. Since it’s on the output side of the gearbox, it’s a much heavier (and more expensive) brake than the primary brake.

“The current load brake is a Weston brake,” said J. R. Clancy engineer Pete Svitavsky. “It has some great features such as self adjustment and purely mechanical ‘self energizing’ actuation. However, due to the amount of energy it absorbs whenever the machine moves downward, there is a practical limit to the size and speed of the load it can control.”
The new electric brake is spring applied and electrically released, acting on the drum shaft. In contrast to the Weston brake, which is applied each time the load is lowered, the new brake is not applied during normal operation, reducing wear and noise.

Speed sensors on the motor and drum shaft let the system compare the actual speed with both the commanded speed and maximum speed. The sensors can also monitor the integrity of the shafting and gearbox, for an added level of security. These sensors can detect problems at the moment they occur and respond quickly. This minimizes the stopping distance as well as the forces on the rigging and the payload.

PowerLifts with SureBrake II will begin shipping in the late summer. For more information on J.R. Clancy, visit www.jrclancy.com.
