1. The Main Points of Buying a Suitable Scissor Lift Platform
Scissor lift platform is more and more popular in the market for its safety, high efficiency and other advantages, and it also promotes the development of the hydraulic lifting platform industry. In the face of so many choices in the market, how can we buy a hydraulic lift with good quality and suitable for our own needs? Or what should be paid attention to when purchasing hydraulic scissor lift platform?
First. Think about the lifting height and capacity
MORN LIFT offers different models of products that vary by travel and lifting capacity, it is very important to do some research on the travel and lifting capacity you want to get from the scissor lift to choose the suitable model of product. In this way, it is possible to get your best solution for lifting equipment with the most appropriate price.
Second. Look at the operating environment of the hydraulic lifting platform
In the meeting room, exhibition hall and other places with low noise requirements, the imported pump station should be considered to reduce noise pollution and interference to life. Sometimes the scissor lift will be used outdoors without external power supply. At this time, the battery or diesel engine can be used as power. The battery can be considered for continuous use in low temperature environment because the diesel engine is not easy to drive in low temperature environment.
Third. Choose the hydraulic lifting platform according to its configuration
Different configurations can achieve different use effects. According to the surrounding environment and their own use requirements, customers can choose the lifting platform with appropriate configuration to achieve better use effects.
Fourth. Predict the use frequency of hydraulic lifting platform
When purchasing the hydraulic lifting platform, if the sales staff asks about the frequency of use, the customer must answer truthfully, and not hide the fact. Based on this, the manufacturer will give special treatment to the equipment when manufacturing, to avoid the customer’s excessive use after receiving the product and causing damage to the equipment.
There are many kinds of hydraulic lifting platform, the most expensive is not necessarily the best. Choose a suitable equipment to make it play its maximum role in the future work.
Power test is the best way to identify the performance of the hydraulic lifting platform. With the help of the manufacturer’s technical personnel, the performance of the hydraulic lifting platform is tested to see if it can achieve the expected effect.
2. Common Problems of Scissor Lift
In the process of using the scissor lift platform, there will inevitably be some problems, which will bring serious inconvenience to use and affect work efficiency if the problems cannot be solved in time, therefore in the following content, I will introduce some common problems to you. When you encounter these problems, you will know how to deal with them.
1 The lifting process cannot be stopped
(1) The travel switch on the scissors lift platform is damaged, replace the travel switch,
(2) The control handle of the scissors lift platform and the button of the distribution box are damaged, repair or replace the handle or button.
2 The scissors lift platform is unable to lift
(1) The overload protection function of the lifting platform is triggered by the overloaded goods. In order to prevent the machine from being damaged, the overload protection device stops the machine.
(2) The supply voltage is too low. Check the power supply voltage to ensure that the voltage of the motor under load is within the allowable range.
3 The lifting platform descends naturally
(1) One-way valve discharge. Check the one-way valve in the valve group. If there is dirt on the sealing surface of the one-way valve, clean the one-way valve.
(2) The pressure relief valve is not tightly closed. Repair or replace the pressure relief valve.
4 The lifting platform does not descend
(1) Lowering valve fault. Press the lowering button, check whether the lowering valve is energized. If there is no electricity, connect to the power supply as soon as possible; if there is electricity, check whether the solenoid valve spool is stuck or damaged.
(2) The lowering speed control valve is misaligned. Adjust the lowering speed control valve. If the adjustment is invalid, replace the speed control valve with a new one.
5 The lowering valve cannot be closed
(1) The lowering valve is damaged or stuck. Clean or replace it.
(2) The lowering travel switch is damaged. Replace the lowering travel switch. For the lifting platform without the lowering travel switch, check whether the time relay operates normally.
These are the common problems you may encounter when using the hydraulic scissor lift. Please find out the problem with the machine you purchased, and follow the above steps to solve the problem and restore your machine to normal operation.
3. Working Principle of MORN Scissor Lift
The working principle for hydraulic scissor lifts is based on Pascal’s law for generating force or motion, which states that pressure change on an incompressible liquid in a confined space is passed equally throughout the liquid in all directions.
The hydraulic scissor lift consists of piston within a cylinder, oil reservoir, pump, motor (used to drive the pump) and valve. Generally, a hydraulic lift is equipped with a machine room, which will house the pump, fluid and motor.
When going up, the pump pushes oil into the cylinder, pushing the piston (which pushes the lift) up. When going down, the valve opens and the oil can flow back into the reservoir, and is pushed back using the gravitational force of the lifting platform.
When the valve is closed, the oil can only go from the reservoir into the cylinder. When the valve is open, the oil can only flow from the cylinder back into the reservoir.
The controls in the lifting platform make the pump operate, moving the oil. When a floor is reached, the pump is switched off and the lifting platform sits on top of the piston, held in position by the oil which is trapped in the cylinder.
This is how the hydraulic scissor lift works.
4. How to Operate Hydraulic Scissor Lifts
Hydraulic scissor lifts are popular industrial lifting platforms for transportation of goods or cars between floors in workshops, warehouses, and underground garages, etc.
Since the goods to be loaded could be heavy and hard to handle, the safe operation of the scissor lift table is of great importance. Now I’m going to talk about some tips on how to safely operate a hydraulic scissor lift.
- Hydraulic oil and battery fluid inspection
First, check whether the hydraulic oil is leaking or the oil level is appropriate, refuel it if necessary. And check whether the battery fluid is leaking and the liquid level is appropriate, add distilled water as needed. Meanwhile, ensure that all labels are clear, legible, and properly positioned.
- Components inspection
Second, check and ensure the components of the scissor lift platforms are not damaged, improperly installed or missing, including the electrical components, hydraulic hoses, battery packs, drive motors, gaskets, tires, wheels, limit switch, platform overload component, indicator light, platform control handle, brake parts, etc.
- Cracks and tightened inspection
Finally, check whether the entire scissor lift platform has cracks, dents or damages in weldment or structural parts; ensure that all structural parts and other key parts are complete, and all related fasteners and pins are in the correct position and tightened; make sure that the battery tray and oil pump tray are closed and locked, and the battery is connected properly.
The tip-over of scissor lifts in operation has frequently resulted in the death and/or severe injuries of workers. Many of these incidents were associated with lift tip-over or workers falling within or from the platform. Many of them can be prevented by enhancing safety awareness and following the steps stated below:
1.Install the hydraulic scissor lift on a solid and flat ground
When operating a scissor lifting platform, be sure to install it on solid and flat ground. the tip-over or tilting of the lift platform can be avoided when four tires are firmly fixed on a horizontal plane.
2.Figure out the weight of the cargo to be loaded
When operating a hydraulic scissor lift, the operator must figure out the weight of the cargo to be loaded. For cargoes that are not marked with an accurate weight, make an estimate of them. If the cargo weight exceeds the maximum load limit of the lifting platform, stop using the machine, otherwise, it may cause damage to the scissor lifting platform or impose risks to the operator.
- Place the loads in the center of the lifting platform
When transporting goods with hydraulic scissor lifts, the heavy loads to be transported must be evenly placed on the center of the lifting platform. Do not place the heavy objects on one side of the lifting table to avoid tip-over.
