Pre-Installation Site Preparation and Positioning
Proper installation of the KTI D-Type Dock Bumper (1000 mm length, 22.5 mm wall thickness) requires thorough preparation of the vertical loading dock substrate. Before mounting, inspect the concrete dock face or structural steel frame for levelness, structural integrity, and surface debris. Any uneven concrete or structural protrusions should be addressed to ensure that the flat rear surface of the 100 mm x 100 mm D-profile sits flush against the mounting surface.
Determine the optimal mounting elevation based on the fleet specifications servicing the facility. The bumper must be positioned to absorb direct kinetic energy from reversing commercial trucks, delivery vehicles, and freight trailers. Aligning the 1000 mm vulcanised rubber extrusion at standard trailer bed contact heights prevents trailer override or underride, protecting both the dock wall and the vehicle chassis from direct collision damage.
Fastener Selection and Mounting Hardware
The 12.7 kg vulcanised solid rubber bumper is engineered for high-impact industrial loading bays and must be secured using appropriate heavy-duty fasteners matched to the specific substrate:
- Reinforced Concrete Dock Walls: Utilize heavy-duty mechanical wedge anchors or expansion bolts of suitable diameter to withstand cyclic impact vibration and dynamic pull-out loads.
- Structural Steel Dock Framing & Channels: Utilize heavy-duty through-bolts or high-tensile fasteners secured through pre-drilled steel backing channels with appropriate locking hardware.
Step-by-Step Installation Procedure
Step 1: Substrate Marking
Position the 1000 mm bumper horizontally or vertically against the dock face at the designated impact height. With the bumper held firmly in position, mark the drill hole centerlines accurately onto the concrete or steel face.
Step 2: Drilling and Core Preparation
Remove the bumper. Using a hammer drill with a masonry bit matching the mechanical anchor diameter (or an appropriate drill bit for steel framing), drill the mounting holes to the specified embedment depth. Clear all concrete dust and debris from the holes using compressed air or a wire brush.
Step 3: Bumper Mounting and Fastening
Align the rubber bumper over the drilled holes. Insert the heavy-duty mechanical anchors or through-bolts through the bumper mounting apertures into the substrate. The hollow D-profile core (50 mm x 50 mm inner dimension) provides internal access for tool clearance during fastener tightening.
Step 4: Torquing and Flush Seating
Evenly tighten the fasteners in an alternating sequence along the 1000 mm length to prevent localized rubber distortion. Ensure the 22.5 mm solid rubber base is pulled tight and sits flat against the dock wall without pinching or excessive preload stress.

Post-Installation Verification and Retorquing
Following initial installation, verify that the 100 mm x 100 mm outer profile is aligned squarely with the dock edge. Recurring vehicle impact vibration can induce fastener loosening over extended operation. Establish a periodic maintenance schedule to inspect anchor tightness, retorquing hardware as required, and visually inspect the vulcanised rubber body for severe cracking, deep gouging, or compression fatigue.
