When purchasing an aluminum alloy lifting platform, several key factors must be taken into account to ensure you make the right choice. For instance, if your primary working environment is indoors, with a lifting height requirement of up to 10 meters, and only one person will be operating from the platform, it is advisable to opt for a single-column aluminum alloy lift. This recommendation stems from several practical considerations: firstly, standard single-column aluminum alloy lifts can already reach heights of up to 10 meters without requiring customization, making them a reliable and mature option. Secondly, their compact external dimensions—measuring 1.42m x 0.78m x 1.97m—make them easier to maneuver through tight spaces like elevators. Additionally, these platforms are significantly lighter; a 10-meter single-column model weighs approximately 420kg, whereas its double-column counterpart tips the scales at 690kg. From a logistical standpoint, the reduced weight makes moving and positioning the single-column model far simpler. Furthermore, from a cost perspective, choosing a single-column lift is typically more economical when it fulfills your needs. However, if greater load-bearing capacity is necessary and the single-column option falls short, then a double-column or multi-column model would be more appropriate.
It’s also important to note that the platform's lifting height differs from the actual working height. The total working height equals the lifting height of the platform plus the height of the worker standing on it.
When deciding whether to invest in a self-propelled aluminum alloy lift, consider how many operators will be involved—either one or two individuals—and whether they will be working on the platform simultaneously. If the operational area is limited and the surrounding environment permits the use of a self-propelled unit, this could be a worthwhile investment. While such models tend to carry a higher price tag, their mobility and ease of operation can dramatically enhance productivity.
In summary, when buying an aluminum alloy lift, it’s essential to evaluate all relevant parameters comprehensively based on your specific needs. Engaging in detailed discussions with the sales team can help ensure you select the most suitable product, preventing potential financial losses due to oversight. Always remember that thorough planning and communication with professionals can save both time and money in the long run.
Auxiliary Agent For Concrete Retarder
Classification by structure:
(1) Sugar: sugar calcium, gluconate, etc
(2) Citric acid, tartaric acid and their salts
(3) Zinc salt and phosphate
(4) lignosulfonate
Hardening effect
(1) Influence on strength, excessive incorporation will cause the concrete to remain unsolidified for 24 hours or even 72 hours, thus affecting the need for early strength of concrete and delaying the construction progress. No obvious effect was found on the concrete of suitable age.
(2) The effect on contraction, the appropriate use of the contraction has no significant effect. Excessive use will cause the top concrete to dry and shrink due to excessive water evaporation and shrinkage cracks.
(3) The effect on frost resistance durability is similar to that of concrete without adding retarder. [1]
