How to identify the quality of the lifting rack

The structure of the lifting and drying racks is not complicated, and there are mainly five parts of the drying rod, the wire rope, the hand shaker (controller), the steering device and the top seat, and some lifting drying racks are also equipped with hangers. The choice of drying racks usually depends on seven places: drying rod thickness, drying rod material, drying rod surface, wire rope, pulley, hand crank, expansion screw.

Raiders one: look at the thickness of the drying rod

Buy the lift drying rack pole is not as thick as possible, but moderate. Too thick a pole that shakes too heavy and is not suitable for lifting. The thickness of the rod should be moderate, and the thickness of 1.0 to 1.2 mm is suitable.

Raiders 2: look at the material of the drying rod

The drying rod is usually equipped with two drying rods. The material is mainly aluminum tube, because the aluminum surface can be used for various surface treatments (anodizing, sandblasting, fogging silver), making it look beautiful and decorative. At present, there are stainless steel, aluminum-magnesium alloy, silicon-magnesium-titanium-aluminum alloy on the market. Consumers should distinguish the materials. First, pay attention to the description of the business, choose a reputable business, and secondly, directly apply the ends of the lever, the aluminum alloy is often Will bend, can not be reduced, titanium alloy will not.

Raiders 3: Look at the surface of the pole

The surface treatment of the drying rod mainly includes polishing treatment, electroplating treatment, spray treatment and electrophoresis treatment. The electrophoresis process is the most complicated, and the surface of the rod is very bright and the grade is the best. The polishing process is the simplest and belongs to the low-end product. The surface of the rod looks very bright and close to the primary color of the aluminum alloy, but it has not been subjected to any surface oxidation treatment. After a long time, the surface of the rod will be black.

Raiders four: look at the wire rope

Most of the wire ropes of the drying racks are made of 202# stainless steel wire, and a few extremely high-grade ones are made of 304# stainless steel wire. The wire rope is divided into two parts, one part is connected to the hand shaker, and the wire rope can be wound into the hand shaker and pulled out of the hand shaker by shaking the handle, which belongs to the hand shaker. The other part is a wire rope that connects the drying rod and connects the hand crank. Look at the thickness of the wire rope, and look at the flexibility. The thicker and softer the wire rope, the better. The method of identification is to fold the wire rope in half, and let it see if it can be restored.

Raiders 5: Look at the pulley

The pulley, also known as the steering gear or the universal wheel, is mounted on the wall and allows the wire rope to pass through the inner pulley to maintain the device perpendicular to the hand. The higher grade product steering gear is made of pure copper wheels. The pulleys are made of ordinary metal, even iron, and copper. The quality of the products using pure copper composite pulleys is good.

Raiders 6: Look at the hand shaker

The hand crank is the core component of the drying rack. It is very important. When you buy it, you should turn the hand crank directly to see if it is smooth and the sound will not be too loud. The gears with lower grades on the market are mainly geared, while the higher grades are integrated spring locks.

Raiders seven: look at the expansion screws

This is often overlooked by consumers. Good products are often equipped with good screws. This also determines whether it is easy to install and whether the installation is an important factor, which indirectly reflects the quality and strength of the product.
