Link Manufacturing LB20 Spring-Assisted Loading Ramp Rear or Side Door Mount 1500 Pound Capacity Model LB20-36-108
The LB20 series offers a versatile and high-capacity mounting solution for commercial vans and medium-duty box trucks. Engineered to mount just inside the vehicle’s rear or side doors, these low-profile aluminum ramps provide a stable, professional-grade platform for frequent loading and unloading tasks. By stowing vertically within the cargo hold, the ramp remains protected from road debris and harsh weather, ensuring a clean and reliable operation while occupying less than 11 inches of horizontal floor space.
Constructed from extruded high-strength aluminum, the LB20 is built for extreme durability and is available in weight capacities ranging from 1,000 to 2,000 pounds. The integrated pull-spring assist mechanism significantly reduces the force required to deploy or stow the ramp, making it a safe and ergonomic choice for operators. Each unit features a low-profile transition threshold at the top to ensure a smooth approach for equipment, effectively reducing the risk of lifting injuries and equipment damage during transit.
Features & Benefits
Spring-Assist Technology: Integrated pull springs reduce the manual lifting force required, allowing for smooth and effortless transitions during deployment.
Internal Vertical Storage: The bi-fold design collapses to approximately 7.5 inches in depth, preserving valuable cargo space and protecting the ramp from the elements.
High-Strength Construction: Manufactured from premium extruded aluminum for long-term reliability in demanding commercial environments.
Low-Profile Threshold: Specially designed transition point at the top of the ramp provides bumper clearance and a shallow approach for wheeled equipment.
Integrated Wheel Kit: Standard wheel kit allows the ramp to transition smoothly when deployed on uneven surfaces or varying ground heights.
Streamlined Installation: Units ship fully assembled and mount securely to any flat surface using only four bolts and 11 inches of mounting space.
Quick-Release Operation: Sturdy hinge points and quick-release latches enable the ramp to be unfolded or stowed in just a few seconds.
