A Tallescope, sometimes known as a ‘talley’, is a retractable aluminum alloy ladder with a work platform, usually attached to an adjustable wheeled base. This type of access kit is ideal for use in theaters, hallways, or schools to provide access to lighting equipment for installation, maintenance, or repair.
Tall telescopes typically have a working height of between 5 and 10 m, and provide space for an operator at the top of the ladder. When in the closed position, a Tallescope rests horizontally on its base and can fit through a standard door. However, when fixed in the active position, the ladder can be extended to an adjustable height according to the user’s requirements. Once it is locked in place, the operator can climb the ladder onto the platform and perform work or repairs.
It is important that this type of equipment is used safely and in accordance with HSE (Health and Safety Executive) guidelines. These include:
– Two people are used to transport and stabilize the Tallescope.
– The Tallescope must not be moved with an operator on the platform or ladder.
– Casters must be locked before use and must not “lift” when the brake is applied.
– Outriggers or stabilizers (if applicable) must be activated before use.
Stemscopes also come in compact varieties, which are narrower than standard models to provide access in particularly hard-to-reach places. Most stemscopes have fully adjustable legs and some have adaptations so they can be attached to a trailer.
Aluminum access platforms and towers such as this one are ideal for use in leisure centres, shopping malls and malls, as well as for outdoor use where single point access with a telescopic ladder is required. Stemscopes are a safe and versatile alternative to traditional steps and ladders due to their lightweight construction and ease of transport. They tend to have higher working heights than most stepladders and are therefore much more useful for long reach applications such as theater rigging.
As with any access equipment, proper training must be completed prior to use. Tallescope training can be found at most powered access providers and typically includes assembly and disassembly procedures, risk assessment and pre-use checks, and the use of handrails, stabilizers, brakes and toeboards. The exam includes a written and practical test, and the training can usually be completed in half a day.
Stemscopes are available from many power access rental companies and retailers.
