Lift Platforms Explained
Known under multiple names like cherry picker, platform lift, zoom boom and scissors lift, the lift platform is used for applications in the construction and maintenance industries as well as by fire fighters and emergency workers trying to save lives. While most models are designed only to carry less than a ton, some specialty models have the capability of carrying more weight. The controls are situated both on the platform and at the bottom of the machine. This makes it convenient as only one person is needed to control a lift platform.
There are three categories of lift platform, namely the aerial device, scissor lift and hotel lift. Each category lists unique features that make them more suited for a specified range of applications within the intelligent lifting industry. The biggest difference between them lies in the form of drive mechanism used to propel the platform to a certain place. Other distinguishing factors are price, availability and manufacturers.
Aerial devices normally use hydraulic piston and either a diesel or gasoline motor to function. Nowadays, newly introduced smaller electric powered machine are increasingly gaining popularity as well. These are mostly used to clean windows and lift workers high up to perform their maintenance operations. Their close appearance to a crane and the presence of joints in their lifting arm create a distinction from other models. When they were first developed, they were largely used in orchards, and thus these units are also known as cherry pickers.
The distinguishing factor of the scissor lift is that it can only be moved vertically, which is done normally by a cross section of scaffolding that gets elongated to project the platform upwards. These units allow workers to reach a working area on higher ground by acting as a raising bridge. Operating these machineries could be done in many ways including hydraulic, pneumatic and mechanical. In some cases, depending on which type was used, this machine would be allowed to descend without power, as there would be ample hydraulic or pneumatic pressure. This would allow the operator to come down even during a power failure.
The hotel lift is a smaller mechanical unit that uses rack and pinion to extend. With a limited weight capacity, it too can be raised vertically, just like the scissor lift. These units are sometimes used as wheelchair platform lifts that allow the handicapped gain access to higher stories in any building.
