A BRIEF OVERVIEW OF VARIOUS TYPES OF LIFTING SLINGS

In any industry, whenever a lifting job needs to be performed, some type of lifting sling, which is used with a lifting device, is required to undertake a lifting operation. Lifting slings are used to attach loads to the lifting devices and they come in various forms with specific slings being considered appropriate to lift specific types of loads. Among the different lifting slings that are commonly used across diverse industries are disposable one-way slings, web slings, fibre rope slings, chain slings, wire rope slings, and round slings.

Disposable one-way slings are usually used to lift an object and load it into a vehicle. The slings are disposed once the object is removed from the vehicle and sent to the destination. Flat web slings are commonly made out of nylon as well as heavy-duty polyester, but polyester web slings are a better choice as they are not only resistant to certain acidic substances, but they also have lesser elasticity compared to their nylon counterparts. Web slings are noted for their softness and flexibility and their ability to absorb some level of shock load. Web slings feature a wide load-carrying area and they can be supplemented by additional protective sleeves to ensure better protection of the high-wear sections. Additionally, it is very easy to detect scars or signs of tear in web slings.

Fibre rope slings are used to lift loads that are quite heavy and they are usually made of natural or manmade ropes that may come equipped with different types of end fittings to suit specific needs. Chain slings are noted for their versatility and they come in various lengths, lifting capacities, and link sizes. Notably, chain slings can be combined together in different arrangements to create 2, 3, or 4 leg chain slings. Chain slings can be equipped easily with different types of anchor points depending on your purpose.

Wire rope slings are recognised for their strength and they appear in different forms, which is why it is important to practise prudence while choosing the right type of wire rope sling for the right application. Wire rope slings come in single as well as multiple leg versions and they are made up of multiple strands that have a better capacity to absorb the shock of loads. Round slings feature a fibre core that remains protected by a tubular sleeve and they are typically used to lift delicate objects.

When you choose a lifting sling, you will need to consider a number of factors including load-type, weight, lifting frequency, and the type of lifting movement that a job would demand.

Aluminum doors are doors with aluminum alloy as the frame and inlaid glass. The following is its relevant introduction:

1. Structural composition

Aluminum alloy frame

The aluminum alloy frame provides a stable support structure for aluminum doors. Aluminum alloy has the advantages of high strength, light weight, and corrosion resistance. Its profiles can be made into various shapes and sizes according to different design requirements, such as common squares, rectangles, etc., and can be anodized, powder sprayed and other surface treatments to achieve beautiful and durable effects.

Glass part

Glass is an important part of aluminum doors, with functions such as lighting and transparent vision. According to different needs, ordinary transparent glass, frosted glass, tempered glass, hollow glass, etc. can be selected.

Ordinary transparent glass has good light transmittance, but its safety and heat insulation and sound insulation performance are relatively poor. Frosted glass can protect privacy to a certain extent and is suitable for places with certain privacy requirements, such as bathrooms. Tempered glass has high strength, blunt-angle particles after breaking, good safety, and is often used in public places or places with high safety requirements. Hollow glass has better heat insulation and sound insulation performance, and is suitable for places where the indoor environment needs to be kept comfortable.

2. Types

Sliding aluminum door

This type of door uses tracks and pulleys to push and pull the door leaf left and right. Its advantages are space saving and easy operation. It is suitable for places with small space or not suitable for swing door opening, such as partitions between balconies and indoor areas, entrances and exits of small shops, etc. However, the sealing performance of sliding aluminum doors is relatively weak, and it may not be as good as swing doors in terms of sound insulation, heat insulation and preventing dust from entering.

Swing aluminum door

Swing aluminum doors are connected by hinges and can be opened inward or outward. It has good sealing performance and can effectively block dust, rain, noise, etc. from the outside. The safety of swing doors is also high, and they are suitable as entrance doors for residential buildings or partition doors between indoor rooms. However, swing aluminum doors need to occupy a certain space when opened, and have certain requirements for the surrounding space.
