See how the hydraulically driven scissor-type aerial work platform responds easily to rainy and humid seasons

With the advent of summer, rainfall all over the country has risen rapidly, and high-altitude platforms have encountered various challenges in construction work on site. How to choose the right model to easily deal with this kind of wet and harsh working environment, what kind of performance will the different drive equipment have during the rainy season? Today we have Dr. Gini to take a look at science and technology for everyone and why it is used in rainy summer. Hydraulically driven aerial work platforms have advantages over electric drives.

Failure rate performance

In a wet and rainy environment, the hydraulically driven scissor aerial work platform can be unimpeded: the moving parts of the hydraulic drive system all work under the sealed environment of hydraulic oil, and can be self-lubricating and heat-dissipating, so the parts have a long working life and good sealing performance. , can easily deal with any harsh environment, even if it is bubbled in water can also work properly, the internal components are not affected by the wet weather moisture, stable and reliable operation.

Equipment in a wet environment

The electric drive has a high failure rate during the wet and rainy season: the core component of the electric drive is the electric motor. The motor is composed of a stator, a rotor, front and rear end covers, bearings, and brakes. When the motor is working, it will generate heat. In the process of cooling, if the seal is not good enough, the humid air will be sucked into the motor cavity to form condensation beads, which will cause the metal parts to rust and the insulation of the coil to decrease. The time will be longer. The motor is damaged. While the motor is driven by electricity, it is also powered by electricity. The composition of the electric brake consists of coils, springs, and brake pads. If the equipment is parked on a rainy day or in wet weather and the equipment is operated after a period of time, it may be found that the equipment is unable to walk or is unable to walk, or that the motor becomes hot after walking for some distance. This is because the brake pads on the brake pads are rusted due to the condensation of water vapor and the accumulation of dust. The brake pads are worn while the motor is running, causing the temperature to rise, causing the motor to burn out.

The low failure rate means that the normal working hours of the equipment can be maximized, which virtually increases the return on investment.

Equipment maintenance

Hydraulic drive is simple to maintain and long service life

In wet or rainy conditions, the working conditions are complicated because the hydraulic drive has a much lower failure rate than the electrically driven scissor aerial work platform. If used for lease, the maintenance cost will be greatly reduced. Moreover, the hydraulic drive is relatively mature and stable, and it can achieve accurate control. In normal use and maintenance, the service life can reach more than 10 years!

Electric drive maintenance is complex and equipment life is short

Due to the relatively complex composition of the electric drive, there is no damage to the internal parts of the motor through the sealing of the system to the external contaminants. For example, water and dust in the air can enter the motor through the flow of air. The condensation of water vapor can cause the internal coil of the motor. Short circuit, parts rust; because the rotation of the shaft and the bearing in the motor needs the lubrication of the grease, grease is a good adhesive to the dust, the mixture of grease and dust will enter the shaft as the shaft and the bearing rotates. And between bearings, it will enter the bearing, making the system wear and tear, and dust is also a good conductor, and the formation of mud and condensed water vapor will also make the motor short circuit. These external contaminants, such as regular maintenance and cleaning, will occupy a large amount of human resources. At the same time, the effect will be very general, and the equipment will also be shut down. The hydraulic drive will not have these troubles.

In the return visit to customers in the leasing market, when we were asked about the failure rate of the equipment's driving system, the customer feedback that many of the hydraulically driven scissor lifts had been used for more than five years. The driving system did not move, and even the seals were not used. Change; but the electric drive scissor aerial work platform has to replace the motor every two or three years or to carry out a large-scale motor repair, different driving methods brought about by the great differences in accessories and labor costs.

Construction job site

In order to reduce equipment downtime, the leasing company will inevitably store more parts with high failure rate. The electric driven scissor aerial work platform will occupy a lot of resources, such as the backlog of funds, space occupation, and human resource occupation. , spare parts inventory loss and so on. For the hydraulically driven scissor aerial work platform with a low failure rate, there is no such problem. (This article is from Gini.)
