Cowest Machinery offers a complete range of vacuum glass lifters to solve this problem. From a lightweight lifter that weighs only 46 kg to a heavy-duty machine that carries 2 tons, there is a model for every job. This article introduces the four main series of Cowest vacuum lifters: WSR, TAT, RDS, and Glassboy. We explain what each series can do, and we help you choose the right one.
WSR Series: Battery-Powered Mobile Glass Lifters
The WSR series is our most popular line of glass lifting machines. These are self-propelled, battery-powered vacuum lifters with wireless remote control. They combine strong suction, full electric control, and easy movement on the job site. A single operator can take glass from a storage rack, move it across the site, and install it into position without help.
WSR-800LA: The All-Round Mobile Glass Lifter
The WSR-800LA is designed for medium-heavy glass installation. It can lift up to 800 kg and reach a maximum height of 4600 mm, which covers most building doors, windows, and curtain wall glass.
Safety comes first. The machine uses a dual-pump and dual-circuit vacuum system with two large 500 x 800 mm suction cups. If one vacuum circuit fails, the second one still holds the panel firmly. Light and acoustic alarms warn the operator in real time, so the glass never drops unexpectedly.
This glass lifter is fully flexible. It offers 360-degree endless rotation and 0 to 180-degree tilting. It can shift sideways by 50 mm, turn 90 degrees on both sides, and move up and down for fine positioning. A two-section telescopic arm extends the working range, and all movements are controlled by a wireless remote from a safe distance.
For power and mobility, the WSR-800LA uses a 24 V front-wheel drive motor with 4 kW of power. It can climb a 12 percent slope, so it works well on ramps and rough site ground. Two batteries give 6 to 8 hours of continuous work time, enough for a full day. The charging system accepts AC 110 to 240 V, so the machine works in any country. With a compact body and a weight of about 2190 kg, it is stable during lifting and easy to move in narrow spaces.
WSR-1000M: The High-Capacity Glazing Robot
When you need more power and reach, choose the WSR-1000M. This glazing robot lifts up to 1000 kg and reaches a height of 5000 mm. It uses eight 400 mm suction cups with a dual vacuum system, so even large glass sheets, stone slabs, and metal panels stay firmly held.
The WSR-1000M offers full-range movement: 360-degree rotation, 0 to 180-degree tilting, 90-degree side turning on both sides, 100 mm side shifting, and 150 mm vertical shifting. Its telescopic arm extends up to 2200 mm, and the boom can rotate 15 degrees for wider working coverage. This makes it easy to position panels in tight or high places.
A 5.5 kW front-wheel drive motor gives strong power with 20 percent climbing ability, so the machine handles rough job sites without trouble. The battery system supports long working hours with universal AC 110 to 240 V charging. You can also add optional attachments such as a forklift bracket, a winch, or special suction cup sets, turning this one machine into a multi-purpose tool for glass, stone, and metal handling.
TAT Series: Heavy-Duty Crawler Glass Lifters
For the biggest panels and the toughest sites, the TAT series is the answer. These are crawler-based glass lifting robots with tracked chassis. They move over mud, rough concrete, and slopes where normal machines cannot go.
TAT-1500: The Off-Road Heavy Lifter
The TAT-1500 is a true heavy-duty glass lifter. It carries up to 1500 kg and reaches a maximum lifting height of 8660 mm, with a horizontal outreach of 6200 mm. This covers almost any high-rise curtain wall and facade installation job.
The tracked chassis gives excellent grip on difficult ground, with 15 percent uphill ability. Four hydraulic outriggers lock the machine firmly during lifting, so there is no risk of tipping even at full load. This makes it one of the safest glass lifting machines on the market.
The TAT-1500 is fully electric and controlled by a wireless remote. It offers 360-degree rotation, 0 to 180-degree tilting, 90-degree side turning, 360-degree boom rotation, 150 mm side shifting, and 100 mm vertical shifting. Eight 400 mm suction cups and a dual vacuum system hold heavy glass safely, supported by light and acoustic alarms.
A high-performance lithium battery pack gives 6 to 8 hours of work time, and the 4 kW drive motor provides smooth, precise speed control. The machine can pass through narrow doorways and work indoors or outdoors. Optional attachments, such as a forklift bracket, winch, or custom suction cups, let one machine handle glass, stone, and metal panels.
RDS Series: Heavy Commercial Glass Lifters
The RDS series is built for commercial glass projects that demand the highest capacity. It is the choice for showroom facades, storefronts, and large-scale glass installation.
RDS-2T: The Two-Ton Powerhouse
The RDS-2T is our strongest vacuum lifter, with a maximum load capacity of 2000 kg, or 2 tons. It uses four large 850 x 550 mm suction cups to grip heavy glass firmly, and a DC 24 V battery system keeps the vacuum running without any power interruption.
This glass lifter offers 0 to 90-degree tilting and 360-degree rotation, so operators can align large panels with pinpoint accuracy, even in tight spaces like showroom entrances. It comes with both wired and wireless remote control for flexible operation. With an IP43 protection rating, it is safe to use outdoors and in semi-open work areas.
A real example shows its power: a commercial showroom needed to install a glass facade panel of about 1.8 tons. With the RDS-2T, a small team lifted the glass from the delivery truck, moved it into position, and completed the installation in a few hours. What would have taken a full day with manual methods was finished safely and quickly.
Glassboy Series: Lightweight Single-Cup Glass Lifters
Not every job needs a big machine. For small and medium glass panels, the Glassboy series offers a simple, portable solution. These are lightweight single-cup glass vacuum lifters that you can carry to any work area.
Glassboy 350D and 550D: Portable and Easy to Use
The Glassboy 350D handles up to 350 kg, and the Glassboy 550D handles up to 550 kg. Despite this strength, the machines weigh only 46.5 kg and 53.5 kg. A dedicated transport cart makes it easy to move them between work zones.
Both models use a dual vacuum system with a single large suction cup, so the grip is steady and slip-proof. They offer 360-degree rotation and 0 to 90-degree tilting for precise positioning. A dual-button release system prevents accidental loss of suction, and an IP43 rating allows light outdoor use.
The Glassboy lifters run on a DC 12 V battery with universal AC 110 to 220 V charging. They are perfect for window fitting, glass factory work, shopfront renovation, and any job with small to medium panels.

Vacuum Glass Lifter FAQ
What is a vacuum glass lifter? It is a machine that uses suction cups and a vacuum pump to grip, lift, and move glass panels safely. It is widely used for glass curtain wall installation and glass handling.
How much weight can a Cowest vacuum lifter lift? Cowest offers models from 350 kg up to 2000 kg. The Glassboy series covers 350 kg and 550 kg, the WSR series covers 800 kg and 1000 kg, the TAT series reaches 1500 kg, and the RDS series handles up to 2000 kg.
Can I use a glass lifter outdoors? Yes. Most Cowest models are battery-powered and built for outdoor use. The RDS-2T and Glassboy series have an IP43 rating, and the WSR and TAT series are designed for construction sites with slopes and rough ground.
How long does the battery last? Most models work for 6 to 8 hours on a full charge, enough for a full working day. Charging is simple with standard AC power from 110 V to 240 V.
Do I need training to use a vacuum lifter? Basic training is recommended. The machines are easy to control with a wireless remote, but operators should always follow the manual, check the suction cups before use, and never exceed the rated load.
Why is a dual vacuum system important? A dual vacuum system uses two independent pumps and circuits. If one circuit fails, the second one still holds the panel. This prevents glass from falling and protects both workers and materials.
