One. introduction

China electric stair climbing dolly is a new type of stair climbing equipment. Electric load stair climbing machines are widely used in transportation, distribution, and other related industries. It can reduce the burden of heavy object handling at work and improve work efficiency. Without the help of others, a stair-climbing trolley, which can quickly complete the work of heavy objects upstairs, is efficient transportation and distribution equipment.


How can we find the proper stair climber? What kind of electric stair climbing car is good? Share some relevant information for your reference.


Two. Design principle of electric dolly stair climber

China electric stair climbing dolly is divided into two parts: the control part and the body part.


  • The primary function of the control part is to control the motor movement of each part of the car body, including the forward and reverse rotation of the front and rear gears and the forward and reverse process of the front and rear wheels.

  • The critical part of the car body is the climbing mechanism. The climbing mechanism adopts two sets of rack and pinion mechanisms, each located at the front and rear.


The principle of electric stair climbing dolly is that the front gear rotates forward to lift the front load and the front wheel when the first step is started. When the front wheel rises to a height of a degree, the rear wheel turns, and the front wheel is placed on the next step. The rear wheel stops rotating, the front gear reverses, and the rear gear rotates forward so that the middle of the car body can be lifted; at this time, the front and rear wheels move forward at the same time so that the seat of the car also falls to the upper step, and then reverse the rear gear and lift the rear wheel Level with the front wheel and move on. In this way, the car went up a step smoothly. In this way, the cycle has been continued, and the trolley can smoothly climb the stairs.


Compared with other cars that can go upstairs, China electric stair climbing dolly has the following advantages:

(1) The design principle is intuitive.

(2) The trolley has a simple structure and is easy to manufacture.

(3) Stairs with variable height can be climbed.

(4) The whole climbing process can keep the body moving safely and smoothly.

(5) According to the principle of ascending, descending steps can also be performed.


Three. electric stair climbing dolly structure

1. Materials

The most widely used materials for electric dolly stair climbers on the market are carbon steel and aluminum alloy. The carbon steel material is economical and can achieve high-strength rigidity, making the machine more durable; the aluminum alloy material is lighter and easier to carry. Its material strength is equally strong and durable.


2. Battery

China electric stair climbing dolly battery recommends the use of lithium batteries. Lithium batteries have a high cost, strong energy density, and are relatively lightweight, which can better control the weight of the entire machine (lead-acid batteries are about 4-5 times heavier than lithium batteries); it can significantly reduce the labor generated by carrying.


3. Protection level

We will inevitably encounter bad weather and environment in our daily distribution process. The electric dolly stair climber must provide a safe operation design and corresponding protection measures such as waterproof and dustproof. It can effectively avoid water splashing and dusty situations in life and prevent the machine from malfunctioning during operation.


4. Tires

Solid tires are wear-resistant and puncture-resistant, and are more suitable for use in harsh environments; pneumatic tires have better shock resistance. In the process of handling heavy objects such as household appliances and fragile goods, pneumatic tires can better buffer and reduce damage to goods.

Four. China electric stair climbing dollyEase of operation

The key to using a stair climbing machine is the operation skills. A good stair climbing machine should be easy to learn and master the operation quickly.


1. Security

In addition to skilled operation skills, the machine operation switch adopts a touch-type (click to move) design, press to move, release to stop; the touch-type design can effectively avoid accidents during distribution and handling.


2. Stair climbing speed

It is a mistake to blindly pursue speed without considering the safety of operators and items. The rate of the electric dolly stair climber needs to be reasonably assumed. The speed should be well designed to ensure the weight limit of the operator and the safe handling of the equipment. It is recommended to have two speeds, one fast and one slow. The slow gear setting is usually used for beginners to practice. After you are proficient, you can choose the quick file to improve work efficiency.


3. Noise

When working indoors, it is necessary to consider whether the noise generated during the operation of the stair climber affects people's everyday life. When the electric dolly stair climber operates, most noise comes from the motor. To better control the noise, the selection of the motor is also a knowledge. The brushless DC motor is recommended. To ensure the maximum load of 200 kg, the noise can be kept at a reasonable level and controlled below 70 decibels.


4. The core technology of the product

The core technology is like the human brain for electric machines like the electric dolly stair climber. The control system of the heavy object climbing operation must be stable, have a low failure rate, and durable. Therefore, it is essential to choose an experienced R&D team who can provide strong support for our core technology. This will give you more peace of mind when using the device.


5. Fast after-sales service

The quality and function of the product itself must be considered when purchasing a suitable electric dolly stair climber, but after-sales service is also essential. Choosing a company with strength and brand protection can solve your worries.


Five. How to maintain China's electric stair climbing dolly?


1. If the electric stair climbing dolly works in a high temperature and high humidity environment like this summer, it is prone to performance degradation, so the workers should usually place the stair climbing dolly indoors to ensure that its metal The structure is more stable, can exert its performance, and can prolong the life of the battery at the same time!


2. Do not put the stair climber in the car's trunk. After using the electric dolly stair climber, many customers directly prevent the stair climber from the box and then park it in the sun exposure environment because of the electric dolly stair climber. The power supply is the battery. For any storm, we must be careful not to prevent it from being in a high temperature and airtight environment, which is a dangerous thing.


3. It is necessary to regularly check the parts of the electric dolly stair climber to effectively avoid the damage of the plastic parts from breaking or deforming due to the high temperature and ensure the safety of the stair climber. Before using the stair climbing machine, carefully check the screws and other parts of the stair climbing machine to ensure that there is no problem before starting to use it.


4. Pay attention to charging in time. In summer, it is necessary to change frequently to ensure that the battery is always in a "full" state to ensure the battery life and the electric dolly stair climber operate normally. At the same time, choose to charge it in a dry, ventilated, and no direct sunlight environment, but do not charge overnight, and the charging time should not be too long. It is recommended to set it at least once a month. Otherwise, it will seriously affect the battery life!
