The SHR-5100 Shadow Hook Dok-Lok vehicle restraint from Rite-Hite is a third-generation rotating hook that can minimize safety risk while maximizing uptime in the most demanding loading dock environments.
The spring-loaded structural hardened steel housing automatically positions when a backing trailer contacts the unit. Engagement range extends from 9 to 30 inches above the ground, with the option for a 9 or 12 inch carriage.
Standard on 9 inch carriages, the dual-articulating nose extension ensures widest range of coverage and helps protect the SHR-5100 from potential damage when servicing rear impact guards (RIGs) lower than 22 inches.
An enhanced dual-clad track helps minimize damage for heavy loading environments or aggressive pull-out attempts up to 32,000 pounds.
Heavy-duty needle bearing carriage rollers and needle hook shaft bearings reinforce high-pressure points to reduce costly downtime and unplanned maintenance.
The SHR-5100 is IP-68 flood-protected and the chainless motor has few moving parts.
The Shadow Hook machined steel hook with zinc dichromate finish comes standard with a spring-loaded, latch-free Shadow Hook cover that provides wrap for a wide variety of RIGs, including outdated ICC bars, 4x4 RIGs, pentagonal RIGs, and intermodal trailers while also creating a 5-inch vertical barrier for obstructed RIGs.
