While it is true that you need to hire glass lifting equipment only and only from the reputed companies for obvious reasons, there are still other safety measures that need to be taken into account, apart from taking into account their technical aspects of the machines.
The weather conditions....
This is the first and foremost factor that needs to be taken into account when it comes to using these glass lift machines for hire. Remember, most of these machines follow the principle of air vacuums, and hence, dry surfaces are imperative, when it comes to using the equipment. You must keep in mind that the absence of sunlight means the air will be heavy with moisture even if it does not rain. And when it rains it is doubly risky to use these machines as the rainwater will make the load wet and as a result of this, the vacuum might fail to act on the load, thereby losing grip on it, and dropping the glass.
The Wind Speed....
In most cases, these glass lifting machines are used for the installation of glass at fair heights. Thus, you must take into account the wind speed. Ideally, the wind speed in case of installing glasses with the help of these tools should be within 18 mph, though that strictly depends upon the height at which the equipment is being operated. There can be a little bit of laxity in wind speed if you are installing the glass at not a very significant height. Wind speed of more than 18 mph might leave the load unstable and toss the equipment off-balance, thus causing a disaster of Himalayan proportion.
And also, you must be wary about the temperature....
Work with these machines while the temperature is modest. Since these machines work with the help of a vacuum, a too-high temperature might make the rubber or whatever material the vacuum is made up of, a bit more lucid and the lucidity might cause these vacuums to lose their grip over the load. Likewise, when you work at too low temperature, it might stiffen the material of the vacuum, which will cause the flexibility of the vacuum to diminish by a considerable extent. Again, this lack of flexibility of the material will harden it and cause it to lose its grip over the load.
The size of the load.....
Installing a smaller than permissible limit of the load is all right, but that permissible limit has to be maintained at any cost. If the load crosses the permissible limit, or if the load is too heavy, and beyond the SWL (Safe Working Load) it is a red flag. This may again cause the equipment to trip.
