This makes the weight of the vehicle, which do not allow that this lock can unlock unless the process resumes of rise about using cm by activating the hydraulic pump. At the moment that is an its locked position, is indifferent to loss of hydraulic pressure, which cut a sleeve losing all hydraulic oil circuit or broken engine, because you vehicle will never drop. -Does not require electrical consumption for the descent. DESCENTS BY PRESSURE RELIEF. In all hydraulic lifters, the descent is through hydraulic pressure discharge, which facilitates shock controlled at all times, and prevents both electric usage because it does not require any power as in the case of electrical failure element or motor. Negative:-mandatory review of fastening screws.

This becomes a factor absolutely essential for the safety of the worker or person that is around the elevator, since usually these elevators are built to work with much larger electrical elevators or screw weights, factor which causes that it can occasionally during intervals of three to six months if the use is very intensive, give symptoms of loosening the nuts holding each column to the floor. Subject to compliance with the intervals for review of these nuts, the base of does not present problems, and where they are not respected, they do not loosen, except for concepts that are on non-flat bases, that their first tighten not be He made correctly. The possibility that one of the nuts securing the base to the ground, loosen completely to stop pressure on the base, is almost non-existent. The case which is made one last squeeze with a maximum strength and after an interval of 6 months with the use of intensive workshop, it may be the case, that the operator makes you feel that you can return to tighten some millimeters of turning any nut in question. However, while not recommended chemical solutions for these situations of fixed type there are liquid screws as chemical dowels. This is the first part of a broad article that ira drafted Cristian Gismera, responsible for sales under the activity of manufacturing and distribution of elevators of car next to other machinery on behalf of PRESTIGE Spain LIFT. We hope that this article has helped and at once advised when making a decision about the use and need for elevator. All information and advice expressed in this article is the opinion of exposed by Cristian Gismera thanks to the result of all the Group of workers forming PRESTIGE LIFT ESPAnA obtained during more than 10 years of continuous production or distribution of products by Spain, Romania, France, Italy, United States, Colombia, Bolivia Argentina, Ecuador among others.

Continue. Gentlemen, nice for having arrived and paid attention to the first part of this article, with the most sincere congratulations expressing our affection and waving us on behalf of PRESTIGE LIFT with a big hug. Please excuse all the spelling errors since this article is in draft format.

This technique is implemented for many years in all lifters European, providing a positive and negative aspects. Positive: The positive part of this, is security, usually, very difficult is that in any part of the route, moving parts can fail causing a collapse of the vehicle thanks to which this guidance by both columns and at the same time situated anywhere on the entire route over your screw without end. Possibilities that one day fails and splitting a worm are very low, being over others as a break in the parties that support the weight of the vehicle. Negative:-large current consumption: the entire movement of ascent and descent, occurs through movements fractionated by bolts, sprockets and chains. This makes requiring large peaks of correine both in ascent or descent. This is one of the reasons of because these elevators were marketed with three-phase Motors 380v / 400v and still weren’t able to develop great efforts. When they tried to transform to 220v single-phase motors, did not work in all their duties, mainly if the vehicle was something heavy, and stopped the rise in any part of the race, then I had no strength for reanudad a new ascent, forcing down the vehicle to the ground and starting a new ascension. -Reduced maximum load capacity: normally these elevators were traded in order to uses with vehicles not exceeding 1,500 Kg the Basic or 2,500 Kg special ones. This has created for many decades, that the workshops be limiting in terms of vehicles or loads of these, especially industrialists. We remember having served elevators our new calling us alerted by need for urgency, because they had experienced cases with elevators with well-known brands in Europe and Spain sold by the same brands and manufacturers with cases as having a vehicle of type tourism with the boot over charged and elevator didn’t have enough force to elevate this.
