The products offered for sale by LSC are intended for use in rescue operations and survival . Inherent to all rescue and survival environments is an increased risk of injury and/or possible death to an individual or group of individuals. The equipment offered by LSC is intended to aid the professional rescuer(s) and/or survival victim(s). However, the risk of injury or death cannot be completely eliminated or foreseen. Equipment training, maintenance and continual reviews of user proficiency is vital to the proper and safe use of all rescue and survival equipment. It is the responsibility of the purchasing and end-user organization or individual to:

  • Determine the suitability of equipment for the selected application.
  • Define the operational procedures and safety guidelines associated with the proper utilization, maintenance (including service life) and storage of the rescue and survival equipment.
  • Ensure that all individuals are thoroughly trained and familiarized with the intended purpose, correct use and function, and serviceability of the equipment.

The wedge style Quick Splice is designed for in flight emergency replacement of the helicopter’s hoist hook. Designed for 3/16" diameter, 19x7 hoist cable only. Constructed of anodized aluminum with stainless steel fasteners for strength and corrosion resistance. The wedge will increase grip on the cable as the load increases. The thumbscrew is used to secure the cable within the Quick Splice until a significant load is applied. Each unit is proof load tested to 2,100 lbs. The design provides for full rated breaking strength of the cable. The #197 is supplied with LSC’s D-Lok Hoist Hook, and #199 is supplied with a shackle for attaching a user supplied hoist hook.

Maintenance and Inspection Requirements

Acceptance Inspection

All LSC equipment passes rigorous quality inspections during manufacture and prior to shipping. However, given the high-risk nature of professional rescue, LSC recommends a formal acceptance inspection be performed and documented in accordance with local policies. The acceptance inspection should include - at minimum - all pre-use inspections below. Should any discrepancies be found or suspected, please contact LSC immediately by emailing [email protected] or by calling +1-813-538-3170.

Operational Inspection

Visually inspect the entire assembly for damage and proper function of the wedge prior to each use. Inspect the attached hoist hook per the hook manufacturer's instructions.


To be performed

Carefully inspect the assembly for cleanliness, cracks, distortion, broken or missing parts, loose screws, unusual wear, corrosion, etc. Check wedge and attached hook for proper operation. Check for proper spacing between the wedge and housing by inserting a piece of 3/16", 19x7 hoist cable and pull up the wedge with the thumbscrew until finger tight. Ensure that the wedge has at least 40% of available travel remaining - instructions below.

Repairs and Maintenance

Maintenance of the Quick Splice should be limited to cleaning with mild soap and fresh water, thoroughly rinse assembly and allow to completely dry. Follow the hook manufacturer's instructions for repair and maintenance of the attached hoist hook. For damaged equipment return the assembly or contact Lifesaving Systems Corp. for serviceability determination.

Product Use

Cut the hoist cable above the damaged area with a suitable cable cutter (LSC cable cutter P/N 195 is recommended).

Re-twist the cable strands of the cut cable as required.

Refer to figure 1 on back for the following steps: Rotate the thumbscrew fully counter-clockwise as per instruction (1) on the housing. This positions the wedge for cable installation. Check for ease of wedge travel by lifting the thumbscrew. The wedge must have full range of travel in the housing for sufficient grip on the cable to occur. Never use the Quick Splice if any doubt about it’s condition or proper use.

Full travel of the wedge can be confirmed visually through the window (3). Without the cable installed, the wedge should freely travel from the bottom to the top of the window.

Hold the Quick Splice upright and insert the cable between the side plates at the (2) start position. Looking down into the top, guide the cable between the housing and the wedge. Allow 4" to 5" of cable to extend from the bottom and ensure that the cable does not pass through the shackle or bail of the hook. Pass the end of the cable between the wedge and the

housing on the other side until it stops at the top of the window (3). Carefully pull the cable from the top of the Quick Splice to remove all slack from the cable at the bottom of the wedge. Recheck the window (3) to ensure cable is fully inserted. Rotate thumbscrew clockwise (4), finger tight. Wedge should have moved up approximately 1/3 to 1/2 the length of the window. The top corner of the wedge is visible in the window. Try to pull the cable from the Quick Splice.

When properly installed, you should not be able to pull any cable from the Quick Splice.

Disqualifying Events

Any bending of any metal part, failure of any inspection in accordance with these instructions.

Load Limit

600 lb – 272 kg.

Fit a hook to the Shackle:

1. Slide 5/16" shackle through swivel on hook and line up with hole in bottom of splice plate.

Note: The opening on the shackle may have difficulty clearing the swivel on the hook. It is absolutely safe (and effective) to knock the shackle onto the swivel with a light blow from a ball-peen hammer.

2. Screw together using 3/8" nut and nylon locking bolt. (LSC Part# H50 and H051).

3. Engineers will be looking for a torque specification here. There isn't one. Tighten the locking nut at least until the first thread of the bolt is fully exposed but not so tight as to lock the shackle in place against the splice plate. Make sure shackle moves freely. If it does not, adjust as necessary until shackle moves freely.
