What is the angle at which the ladder is used?
Following the 70 degree golden placement angle design, the ladder body forms a scientific inclination angle with the ground, making the center of gravity more stable when standing, and the knee force more evenly distributed. Long term operations (such as wall painting and installation) are also less prone to fatigue, making it more ergonomic than traditional 90 degree vertical ladders.
What is the load-bearing capacity of the ladder?
Triangle support principle: The main frame of the ladder body and the anti shake bracket form a triangular structure, which disperses pressure. When bearing 150KG, each step of the pedal is evenly stressed and not easily bent;
Reasonable spacing between pedals: Each step has a spacing of 40cm, which conforms to human walking habits and makes climbing up and down the ladder more natural, reducing the risk of stepping empty.
What are the characteristics of a ladder?
The length calculation formula: “Purchase length=vertical height+40cm” is the optimal solution that has been tested multiple times to ensure a safe distance between the top of the ladder and the work surface, avoiding being too high or too low;
Segmented locking design: Each step has an independent locking device. After adjusting to the desired height, only the corresponding step needs to be locked, while the other steps remain contracted, which is both stable and space saving;
Anti misoperation buckle: The buckle requires a double action of pressing and pulling to unlock, avoiding sudden contraction caused by accidental contact during use and upgrading safety.
What should I pay attention to when using a ladder?
Before unfolding, check if the ground is flat and avoid using it on slopes or soft soil;
After fully unfolding, gently step on the bottom pedal with your foot to test stability, confirm there is no shaking, and then climb the ladder;
Shrink from top to bottom during storage to avoid structural deformation caused by forced pressing.

Hook Installation Four Steps
Hook type straight ladder, hook can be installed and removed, safe and easy
1. The latch and the hook hole face each other
2. Prepare to push the switch left 360° rotation
3. Insert the hook, release the switch, and make sure the latch is inserted into the hook hole
4. The rotatable hook can be adjusted to the desired angle
Installation Steps for Balance Bar:
1.Unscrew and remove the anti-pressure plug.
2.Slide the balance bar into its designated position.
3.Apply firm pressure to the balance bar to snap the plastic rivet.
4.Secure the balance bar in place by inserting screws.
Correct way to open the ladder
1.Pull open at the top, shrink at the bottom
2.Open all the step
If the ladder is to be used short, the top should be fully opened and the bottom contracted.The middle part of the ladder should not be opened or closed, or should not be pulled into place.
Make sure that both switches are locked at each step before climbing the ladder.
Wrong way to open the ladder
1.The middle step is partially opened and partially closed
2.Middle step not pulled in place (false lock)
