Snatch Block Winch Pulley Heavy Duty for Synthetic Rope and Steel Cable

Description:

Forged Plates, Polymer Sheave: The housing is built from high carbon drop forged steel side plates, six millimetres thick. Forging keeps the grain of the steel running through the plate, so the housing takes an impact load as one piece. An electrostatic powder coat covers the outer faces, the edges and the inner walls. The running surface is a self lubricating aerospace polymer sheave. It carries the rope on a smooth, burr free throat, it needs no grease, and it does not corrode. A sealed bearing set sits between the plates on a hardened axle pin, and the axle pin is what moves the pull from the sheave into the plates.

Where The 14 Ton Figure Stops: Two figures describe this block. Maximum breaking strength is 14 ton, or 30,864 pounds. Working load limit is 4.67 ton, or 10,288 pounds, and that is the figure to rig against. The axle pin is proof loaded to 150 percent of its rating before assembly. The sheave turns on sealed bearings, so a doubled line runs freely and the block returns a two to one mechanical advantage at the anchor. A ten thousand pound winch line in a single leg becomes twenty thousand pounds of pull at the block, while the motor carries half the load.

Mud, Sand And Sideways Pulls: This is a recovery accessory for vehicles that go off the road. It suits self recovery from mud, sand and soft ground, where a straight line cannot reach a solid anchor. It suits angled pulls where the winch line has to be redirected around a tree or a rock, and double line rigging where the load is heavier than one line can move. Commercial towing and fleet recovery work use the same block, because the anchor end of the rig is where the load concentrates. It fits Jeep style 4x4 vehicles, pickup trucks, SUVs and ATVs that carry a winch.

Rope Size, Shackle Size, Fit: The sheave groove takes 3/8 inch synthetic rope and 3/8 inch steel cable, so one block covers both rope types. The ring hole measures 2.02 inch and accepts the common 3/4 inch shackle, the pin size used on most recovery shackles. Groove diameter is 0.5 inch, wide enough for the rope to sit in the throat without pinching. The side plates rotate on the axle pin, so the block opens, drops onto the line and closes again wherever the anchor is. The winch line stays threaded, and the shackle pin locks the plates shut.

The Turn Happens At The Block: The block hangs from the anchor through the ring hole at the top. The winch line enters the groove, wraps the sheave, and leaves the block parallel to the line it came in on. That turn is the whole job of the block: the vehicle moves back along its own track, and the direction change stays at the anchor end of the rig. The ring hole sits above and clear of the sheave, so the anchor shackle and the running rope hold separate contact points. The side plates enclose the groove on both faces, so the rope stays seated through slack moments in the pull, and the sheave keeps the line clear of the plate edges.

Proofed Pin, Closed Groove: The axle pin carries the full pull, and it is proof loaded to 150 percent of its rating before the block is assembled. The side plates close over the groove on both faces, so the rope cannot ride out of the throat when the line runs off axis. The ring hole sits apart from the sheave, which keeps the anchor shackle and the moving rope on separate contact points. Sealed bearings hold grit, mud and water out of the rotation, so the sheave turns freely under load. The shackle pin is the only fastener in the assembly, and it locks the plates closed.

Forged Body, Coated All Over: Drop forged carbon steel side plates carry the load at six millimetres of section thickness, and forging keeps the grain continuous through the plate. The electrostatic powder coat seals the forged surface against road salt, mud and steady sun exposure, and it covers the inner faces as well as the outer. The sheave is self lubricating aerospace polymer, so the running surface needs no grease and does not corrode. Two parts touch the rope: the polymer sheave and the axle pin. One block takes synthetic rope and steel cable.

Opens, Drops On, Locks: Rigging takes one hand. The side plates rotate on the axle pin, so the block opens along the line wherever the anchor is, and the winch line stays threaded through the fairlead and the drum while the block goes on. The rope drops into the groove, the plates swing back into line, and the shackle pin passes through the ring hole to lock them shut. The ring hole accepts the common 3/4 inch shackle, so the anchor hardware a rig already carries is enough for the job. Two to one mechanical advantage arrives with that single movement: one line in, one line back.

Marked For Its Destination Markets: The block is CE marked and built to the EU machinery directive 2006/42/EC. Production runs under an ISO 9001 quality management system. The block is tested against SAE J684, the North American standard for trailer couplings and hitches, and against SAE J2055. Tensile test records cover the breaking strength and the working load limit. The same documentation set carries DOT, GS, EEC and ROHS entries, so the block can go on sale in North America, the EU, Australia and the Middle East with the paperwork already in place.

Checked Before It Leaves: The load test is the last step in the chain, and it runs on every block: a proof load on the axle pin and a tensile check on the assembly. Third party inspection is accepted, and the record of the proof load and the tensile check travels with the parts. The document set carries the CE marking reference, the ISO 9001 certificate reference and the SAE J2055 and J684 test entries. Replacement sheaves and axle pins are supplied as single items under their own numbers.
