Stand-Alone Mobile Deployment Overview
The Trolley Type Truck Wheel Chock (SKU: KTI16031001TWCA) is engineered as a fully portable, stand-alone vehicle immobilisation unit. Unlike embedded or permanently mounted wheel restraint systems, this trolley-mounted assembly requires zero civil works, drilling, or permanent floor anchoring in loading bays, freight docks, or industrial yard facilities. The entire unit measures 900 mm in length, 570 mm in width, and 915 to 920 mm in height, featuring an integrated wheeled base that allows yard personnel to transport and position the 20 kg (± 10%) assembly directly to parked commercial vehicles with minimal ergonomic strain.
Manual Chock Spacing and Tyre Span Adjustment
Prior to tyre contact, the dual wheel chocks must be calibrated to match the specific tyre profile and axle configuration of the target vehicle. The Mild Steel (MS) frame features an integrated manual adjustment mechanism designed to alter the distance between the two chocks between 23 inches and 27 inches.
- Inspect Vehicle Tyre Span: Determine whether the vehicle features single wide-base tyres or dual-tyre axle arrangements.
- Adjust Manual Track: Shift the dual chocks along the trolley adjustment track until the clear span between the chocks matches the target tyre spacing within the 23-inch to 27-inch adjustment range.
- Secure Adjustment Fasteners: Verify that the manual locking fasteners on the sliding mechanism are seated firmly to prevent shifting during wheel engagement.
Positioning and Vehicle Engagement Procedure
Proper mechanical engagement between the chocks and the tyre tread is critical to achieving full vehicle immobilisation up to the rated 40 to 50 ton capacity. Operators should execute the following deployment sequence on flat or sloped loading surfaces:
- Wheel Assembly to Axle: Using the 915/920 mm high handle frame, roll the yellow spray-painted trolley directly to the rear or front tyre set of the parked truck or trailer.
- Flush Contact Alignment: Push the trolley forward so that both integrated chocks make square, flush contact directly against the tyre tread face. Ensure the chocks do not sit skewed or partially offset from the tread path.
- Surface Check: Verify that both chocks sit flat against the ground surface without debris, ice, or loose gravel wedged underneath the contact plates.
- Verify Clearance: Confirm that the high-visibility yellow MS frame remains clear of trailing air hoses, electrical lines, and vehicle mud flaps.
Deployment Verification Table
| Deployment Parameter | Operational Specification / Requirement |
|---|---|
| Vehicle Weight Rating | Commercial trucks and trailers up to 40–50 tons |
| Chock Span Setting | 23 inches to 27 inches (manual track setting) |

| Operating Surface Profile | Flat or sloped loading bays, parking bays, and dock aprons |
Disengagement and Storage
Once vehicle loading or unloading operations are complete and the vehicle is cleared for departure, pull back on the MS trolley handle to roll the dual chocks away from the tyre tread. Roll the 20 kg unit away from the active traffic lane into a designated staging area to maintain clear, hazard-free dock lanes.
