WSR-800LA Self Propelled Vacuum Lifter – 800kg Heavy Load Glazing Vacuum Handler

2026 07/27

For glazing contractors, curtain wall engineering firms, natural stone fabricators, solar installation teams and metal panel processing factories, transporting and installing large flat panels has long been one of the biggest pain points on every construction site. Traditional manual handling requires multiple workers to carry heavy glass slabs, marble sheets and composite plates, which not only brings huge labor costs but also leads to frequent surface scratches, edge cracks and broken panels caused by unstable gripping. Meanwhile, conventional crane-mounted vacuum lifters rely entirely on external hoisting machinery, making them completely unable to operate in narrow indoor spaces, low-rise renovation sites or areas without overhead cranes. The WSR-800LA wireless electric vacuum lifting robot fully solves all these industry pain points, integrating driving, lifting, telescopic extension, multi-angle adjustment and vacuum holding into one compact self-propelled unit, becoming a universal heavy-load vacuum handling solution for flat panel installation projects around the world.

This battery-powered mobile vacuum lifter is built with industrial-grade mechanical and vacuum components, delivering a rated maximum load capacity of 800kg and a maximum vertical lifting height of 4600mm supported by two-stage extendable booms. The dual-section extension structure provides a total outreach of 650mm plus an extra 500mm secondary stretch, allowing operators to reach deep positions of curtain walls, high skylights and overhead interior panels without moving the whole machine repeatedly. Different from bulky crawler vacuum lifting machines that cannot enter elevators or pass through standard door frames, the WSR-800LA owns ultra-compact folded minimum dimensions of 32358801620mm, which enables smooth transportation inside buildings, easy entry into passenger elevators and flexible operation in tight residential or commercial renovation zones. Every structural design of this vacuum handler focuses on on-site mobility and space adaptability, greatly expanding the applicable working scenarios of heavy-load vacuum lifting equipment.

Reliable Dual-Circuit Vacuum Suction System for Maximum Operation Safety

Safety is the top priority for all high-altitude panel lifting work, and this machine adopts a mature dual pumps and dual independent vacuum circuit design to eliminate hidden dangers of sudden suction loss. Two large-format 500*800mm suction cups are equipped as standard, forming full-area airtight contact with smooth non-porous materials including insulated glass, tempered glass, polished marble, granite slabs, aluminum composite panels and solar glass sheets. The dual vacuum system works separately: even if one pump fails accidentally during operation, the other circuit can still maintain stable negative pressure to hold the panel firmly, avoiding falling accidents that would cause property loss and personal injury.

The official load curve strictly matches the actual outreach length of the telescopic boom to standardize safe load limits for all working radii. When the boom retracts to the shortest distance, the machine can bear the full 800kg rated load; under medium extension length, the safe carrying capacity drops to 500kg to keep chassis balance; when the boom stretches to the maximum distance for far-reaching installation, the maximum allowable load is controlled at 300kg. This graded load limitation mechanism effectively prevents overload operation caused by improper manual judgment, lowering site safety risks for every lifting cycle.

Full Wireless Remote Multi-Axis Electric Control with Millimeter-Level Precision Adjustment

All movement functions of the WSR-800LA vacuum lifter are fully electric and controlled by a single wireless remote controller, removing the limitation of wired operation and giving operators free standing positions for better observation of panel alignment. The remote integrates complete control of all core motions, including forward and backward driving, vertical up-and-down lifting, two-stage boom extension, infinite 360° continuous rotation, 0° to 180° full panel tilting, horizontal side shifting within ±50mm, vertical fine shifting within ±75mm and bidirectional 90° side turning on both left and right sides.

The equipment supports millimeter-level stepless speed regulation, so operators can switch fast moving speed for site transfer and ultra-slow fine-tuning speed for precise panel fitting. When installing curtain wall glass or stone facades, workers can adjust the panel’s horizontal position, vertical height, tilt angle and rotation angle without repositioning the whole machine, which drastically shortens the time spent on panel alignment. A single operator can independently complete all installation work that previously required 3 to 5 laborers, cutting labor expenditure by more than 60% while greatly reducing collision damage to high-value glass and stone materials. All real-time core working parameters such as vacuum pressure, lifting height and remaining battery power are clearly displayed on the built-in controller screen, helping operators grasp the machine’s running status at a glance.

Strong Climbing Performance & Long-Lasting Battery Endurance for All Site Conditions

The driving system of this vacuum glass handler adopts a front-wheel 4kW 24V driving motor, with a built-in transmission structure that supports a maximum uphill capability of 12%. It can stably travel on sloped construction ground, factory ramps and uneven outdoor foundation surfaces without slipping or stalling. The power supply system consists of two DC12V 190Ah large-capacity lead-acid batteries, which support 6 to 8 hours of continuous non-stop working after one full charge, fully meeting the daily working demand of a full construction shift.

The charging system supports wide universal AC voltage ranging from 110V to 240V, compatible with power grid standards of nearly all countries and regions globally, so overseas clients do not need to purchase extra voltage converters for on-site charging. The total self-weight of the whole machine reaches 2190kg, providing sufficient chassis counterweight to guarantee stable balance during all rotation, tilting and extension movements, effectively avoiding tipping risks when lifting heavy panels at extended outreach.

Multi-Scenario Application for Global Construction & Manufacturing Industries

  1. High-rise curtain wall and facade glass installation: Handle oversized insulated glass panels at high elevation, with flexible rotation and tilting functions to match various wall inclinations and building facade structures.
  2. Natural stone and marble slab installation: The large suction cups make even contact with polished stone surfaces without leaving marks or scratches, ideal for villa stone facades and lobby decorative stone projects.
  3. Metal sheet and composite plate workshop handling: Complete loading, unloading and stacking of aluminum panels, steel sheets and composite boards inside processing factories, replacing manual forklift handling with higher precision.
  4. Photovoltaic solar panel mounting: Securely lift large solar glass modules for ground photovoltaic power stations and rooftop solar energy projects.
  5. Indoor commercial and residential renovation: The compact folded size allows access through narrow doorways and elevators, suitable for window glass replacement, interior partition glass and small decorative stone installation.

Compared with small handheld suction lifters that can only carry light panels and crane-dependent vacuum lifting equipment limited by external hoists, the WSR-800LA self-propelled vacuum lifting machine achieves full independent operation without any auxiliary lifting tools. It improves site mobility, shortens overall project construction cycles and complies with international workplace safety standards for flat material handling. All core mechanical frames, vacuum pumps, motors and control systems of the WSR-800LA series undergo strict factory performance testing and aging tests before delivery, ensuring long service life and low daily maintenance frequency for long-term industrial use. Whether clients need standard 800kg vacuum lifting machines or customized suction cup layouts for special ultra-wide or ultra-thin panels, this series vacuum handler provides reliable, cost-effective flat material lifting solutions for construction contractors and panel manufacturers worldwide.
