Telescopic ramps
Telescopic ramps do the very thing that their name suggests, i.e. they extend using a telescopic action that typically sees one or more channel sections slide within the other sections. As a result each subsequent telescoping channel is slightly narrower than its predecessor with each channel fitting precisely into the one beneath it.
In the case of a three sectioned telescopic ramp there would be three separate channels. The second channel would sit within the first channel and the third channel would sit within the second channel. When a telescopic ramp is in use the channels slide out of each other to extend the ramp's reach whilst reducing its incline.
Construction and function
There are two types of telescopic ramp, a broad ramp and a twin channel ramp. Broad ramps are single ramps that can take a wheelchair or mobility scooter within their width, whilst twin channel ramps require a pair of ramps with each ramp being used for one side of the chair. Obviously twin channel ramps are unsuitable for a 3 wheeled mobility scooter.
Most telescopic ramps are made from lightweight (anodised) aluminium. This material is strong and it also makes it easy to carry the ramp around and to set it up.
Since setting up a ramp requires extending the channels and ensuring that the two mounting positions are balanced and secure, a lightweight construction is paramount. Most ramps are carried and set in place by a single individual, so weight is a critical factor.
Other construction features to look for include
- Angled lips at the top and bottom of the ramp to ease wheeled access.
- Locators that help secure the top of the ramp to a vehicle or step.
- Non slip surfaces that give traction in all conditions.
- A carry case or bag.
- Vertical edging to prevent a wheeled vehicle from running off the track.
- A locking mechanism to fix the sections in a locked state during use.
Typical specification
Telescopic ramps are produced by many different manufacturers and they come in different sizes, pressings and finishes.
The most popular examples are 5 feet or 7 feet long broad or twin channel ramps that can be used for building or vehicular access. These ramps are sold in pairs and will normally take a minimum combined weight (e.g. wheelchair and occupant) of over 400 pounds (28 stones).
In the case of twin channel ramps, the track width of each channel may be anything from 5 inches up, however, the overall width of the channel (which includes the edge or lip thickness) will be greater than the actual usable track width.
