Telescopic Lip Loading Dock Leveler Ramp Systems
The Madoors USA TLDS-6500 Hydraulic Telescopic Loading Dock Leveler Ramp System is a fully concrete-embedded, hydraulically actuated telescopic lip dock leveler engineered for 24/7 uninterrupted loading operations where conventional hinged lip dock levelers cannot provide sufficient contact area, reach, or vehicle height adaptability. With Italian-production hydraulic equipment, IP67-rated Siemens electrical automation, a movable telescopic lip providing larger contact area between the vehicle bed and the leveler for optimal load utilization, automatic level adjustment to vehicle height, and an integrated docking control system managing the dock leveler, dock shelter, and door from a single control unit — the TLDS-6500 delivers the highest level of loading dock performance, safety, and operational efficiency available in the Madoors USA dock leveler range. All systems carry a 2-year guarantee.
Fully embedded in the concrete floor, the TLDS-6500 presents a completely flat surface with no overflow above floor level on the surface or sides — eliminating the trip hazards, forklift obstruction, and floor space consumption of surface-mounted dock leveler systems. Drop-pattern casting on the platform surface prevents forklift slipping, side protective layers prevent foot pinching injuries, and multiple safety sensors provide comprehensive accident risk protection throughout each loading cycle.
TECHNICAL SPECIFICATIONS
The Madoors USA TLDS-6500 is manufactured in widths from 600mm to 1,200mm with 12/13mm wall thickness hydraulic latch construction — providing a complete solution for loading a wide range of container and trailer sizes. The 600mm long, high-strength, resistive 12/13mm teardrop latch provides the telescopic lip extension reach required for reliable vehicle bed contact across the range of trailer heights and standoff distances encountered at active loading docks.
Italian-production hydraulic equipment provides the reliable, consistent actuation performance required for 24/7 continuous operation. IP67-rated Siemens electrical automation provides complete water and dust resistance for all electrical components in the demanding environmental conditions of active loading dock operations. The hose lock valve instantly locks the system in any position in the event of hydraulic system failure — preventing uncontrolled platform descent and maintaining personnel safety during hydraulic fault events. The safety valve prevents motor straining at maximum lift — protecting the hydraulic power unit from overload damage during high-load operation.
The movable telescopic lip provides a significantly larger contact area between the vehicle bed and the leveler platform than fixed lip systems — allowing the lip to extend onto the vehicle bed and be precisely positioned for optimal load utilization across the full usable width of the trailer floor. Automatic level adjustment to vehicle height eliminates the manual positioning requirement of non-automatic levelers, with the platform and telescopic lip automatically finding the vehicle bed level regardless of trailer height variation between vehicles.
The integrated TLDS-6500 docking control system manages the dock leveler, dock shelter, and door from a single unified control unit — with a small number of self-explanatory buttons eliminating the need for separate steering units, complex wiring between separate control panels, and operator training on multiple independent control interfaces.
Standard equipment on every TLDS-6500 installation includes power LED red-green traffic lights with audible warning system, two 100 × 100 × 300mm rubber bumper wedges for vehicle positioning and dock face protection, side protective layers preventing foot pinching injuries, the 600mm teardrop latch, hose lock valve, and safety valve.
KEY FEATURES
Fully Concrete Embedded — Flat Surface, No Overflow
The TLDS-6500 is fully embedded in the concrete dock floor — presenting a completely flat, flush surface with no overflow above floor level on the surface or sides when in the rest position. This embedded flat surface eliminates the forklift obstruction, trip hazards, and floor space consumption of surface-mounted dock leveler systems, and provides a clean, professional loading bay floor appearance compatible with high-throughput warehouse and distribution center environments.
Movable Telescopic Lip — Larger Vehicle Bed Contact Area
The movable telescopic lip extends beyond the fixed platform edge to provide a larger contact area between the dock leveler and the vehicle bed — reaching further onto the trailer floor to create a wider, more stable transition bridge between the dock and the trailer. This larger contact area directly reduces the risk of forklift wheel drop at the dock-to-trailer transition, increases load stability during passage, and allows more precise positioning on the vehicle bed for optimal load utilization across the full trailer floor width.
Automatic Level Adjustment to Vehicle Height
The TLDS-6500 automatically adjusts its level to match the vehicle bed height of each arriving trailer — without requiring manual operator adjustment for each vehicle. This automatic height matching capability accommodates the full range of trailer heights encountered at active loading docks with mixed vehicle fleets, eliminating the manual positioning delays and potential height mismatch errors that create accident risks and loading inefficiencies at dock leveler systems requiring manual height setting.
Italian Hydraulic Equipment — 24/7 Uninterrupted Operation
Italian-production hydraulic equipment provides the reliability and longevity required for 24/7 continuous operation at active loading docks where the leveler cycles hundreds of times daily across all shifts. The quality of Italian hydraulic components — valves, cylinders, seals, and pump — directly determines the operational availability and maintenance interval of the dock leveler system across its service life.
IP67 Siemens Electrical Automation — All-Environment Reliability
IP67-rated Siemens electrical automation provides complete water and dust resistance for all electrical control components — protecting the automation system from the high-pressure cleaning, water spray, temperature variation, and contamination exposure of active loading dock environments. Siemens automation reliability eliminates the electrical faults and control system failures that cause operational downtime at loading docks with lower-specification electrical systems.
Hose Lock Valve — Instant Hydraulic Failure Protection
The hose lock valve instantly locks the TLDS-6500 platform and telescopic lip in position in the event of any hydraulic system failure — including hose rupture, seal failure, or pump pressure loss. This instant locking response prevents uncontrolled platform descent onto personnel or equipment in the dock pit area, providing the primary personnel safety protection against hydraulic system failure at the most critical moment of a fault event.
Drop-Pattern Casting — Forklift Slip Prevention
The drop-pattern cast surface on the dock leveler platform prevents forklift tire slipping during loading and unloading operations — providing reliable tire traction on the leveler surface under the contaminated, wet, and heavily loaded conditions typical of active industrial loading bays. Anti-slip surface treatment across the full platform width and length ensures consistent traction at all forklift positions during the transition across the leveler.
Side Protective Layers — Foot Pinching Prevention
Side protective layers fitted to both sides of the TLDS-6500 prevent foot and ankle pinching injuries to dock personnel during platform raise, lower, and telescopic lip extension and retraction — a critical safety requirement for dock leveler systems where the moving platform and lip create pinch points that can cause serious personnel injury without effective side protection.
Position Control — Stop at Any Point
The TLDS-6500 can be stopped at any desired position in its travel range — providing the operator with complete positional control for precise vehicle bed matching, lip placement, and load positioning. This stop-anywhere position control capability supports optimal load utilization and personnel safety at every loading cycle.
Integrated Docking Control System — Leveler, Shelter & Door
The innovative TLDS-6500 docking control system manages the dock leveler, dock shelter, and dock door from a single unified control unit — replacing the separate steering units and complex wiring of conventional multi-unit dock control systems with a few self-explanatory buttons in a single panel. This integration eliminates operational errors from incorrect sequencing of separate controls, reduces wiring complexity and installation cost, and simplifies operator training to a single, self-explanatory interface.
Width Range 600mm to 1,200mm — Container Loading Solution
The 600mm to 1,200mm width range and 12/13mm wall thickness provide complete coverage of the container and trailer loading requirements encountered at commercial and industrial distribution centers — from narrow single-door container loading through to wide trailer floor loading requiring maximum platform width and telescopic lip reach.
Reduces Loading Time — Increases Work Efficiency
The automatic level adjustment, movable telescopic lip positioning, and stop-anywhere position control capability of the TLDS-6500 collectively reduce the setup time for each loading cycle compared to conventional fixed lip dock levelers that require manual height adjustment and have limited lip reach — directly increasing the number of loading cycles achievable per shift and the total throughput efficiency of the loading dock operation.
Easy & Fast Preventive Maintenance
Preventive maintenance of the TLDS-6500 is easy and fast — with the embedded concrete installation providing access to all hydraulic and mechanical components through the platform surface covers, and the Italian hydraulic equipment requiring only standard maintenance procedures at extended service intervals. Quick maintenance access and simple service procedures ensure that preventive maintenance can be completed within normal operational windows without extended dock downtime.
