Feature overview

1.Easy and safe to open the lid. Using the special mechanical structure to avoid accident.

2.Auto-hold at the various position and prevents the tiny rubbish to drop down.

3.Easy specification of the balancer can apply to the different lids.

4.Easy to adjust the torque with the visuality function, constant power can be worked with in the usage.

5.Easy to assemble. The design of integrative structure and the special spring make it completely free maintenance.

6.Opening the lids aslant can be allowed, the maximum oblique angle of W10-W50 is 40 and the maximum obligue angle of W70-W350 is 30, it depends on the torque calculation under the different oblique angle.

Product Parameters

Installation and commissioning instruction

1.Confirm the minimum gap between the base and the top cover, then measure the minimum distance between the cover and the base.

2.Make sure the COB (Connection panel Of the Balancer) and the COc (connection panel of the top cover) are parallel to each other. please use the horizontal adjustment bolt or install the auxiliary washer.

3.According to the size of the base and top cover, making-off the COB and cutting.

4.Welding the cOB, the base plate of top cover and the preassembled accessory together.

5.Confirm the welding strength then do the preliminary test.

5.1 Open the top cover to the position with maximum angle

5.2 For w10-w5o, Rotate the torque adjuster to the opening direction, enhance the pre-torque and screw the bolts firmly.

For w70-w350, Rotate the torque adjuster into the adjustment hole in order of (1)- (2), fix and enhance the pre-torque.

5.3 Under the condition of protection, please close the top cover. Also it should be hold between 10-20° smoothly otherwise please retry the Step.5.2 again.

5.4 Welding and make sure the welding strength quality, rubbing down smoothly.

6.Fine-tuning the opening cover angle (horizontal adjustment bolts) if need.

7.For it needs to keep opening statue or person need to operate into the lid during the working process.After the top cover is opened completely, secure the bolts in the anti-dump spout.

Usage Instructions for Lid balancers

Proper installation and usage of lid balancers maximize their performance and extend their service life. Here are step-by-step guidelines:

1. Installation

Positioning: Ensure the lid balancer is mounted at the correct angle and distance according to the lid’s size and weight.

Secure Mounting: Use appropriate bolts and brackets to attach the balancer firmly to both the lid and the base.

Alignment: Make sure the lid balancer arm or strut aligns with the hinge mechanism to avoid uneven load distribution.

2. Operation

Opening the Lid: Apply gentle force to start lifting; the balancer will gradually take over and support the weight.

Holding Position: Once open, the balancer keeps the lid at the required angle. Some models allow adjustable positioning.

Closing the Lid: Apply steady downward force. Gas or spring-loaded balancers will slow the closing motion to prevent sudden slamming.

3. Maintenance

Inspection: Check regularly for wear, rust, or gas leakage.

Lubrication: If applicable, lubricate hinges and moving joints to reduce friction.

Replacement: Gas strut balancers lose pressure over time and should be replaced when performance weakens.

Common Problems and Solutions

Despite being durable, lid balancers can experience issues if not properly maintained. Below are typical problems and their troubleshooting methods:

1. Lid Fails to Stay Open

Cause: Gas pressure loss in gas struts or weakened springs.

Solution: Replace the lid balancer with a new one of the correct capacity.

2. Lid Closes Too Quickly

Cause: Incorrect installation angle or misalignment of the balancer.

Solution: Reinstall according to manufacturer guidelines and check hinge alignment.

3. Noisy Operation

Cause: Lack of lubrication or internal wear.

Solution: Apply appropriate lubricant to moving joints, or replace worn components.

4. Difficulty in Lifting the Lid

Cause: Balancer capacity too low for lid weight.

Solution: Upgrade to a higher-capacity lid balancer designed for the specific lid dimensions and weight.

5. Corrosion or Damage

Cause: Exposure to moisture, chemicals, or extreme conditions.

Solution: Choose stainless steel or coated balancers for harsh environments, and replace corroded parts immediately.
