Heightec once marked some of their products with the "heightec-PMI" brand for sale by PMI in the U.S.A.

I acquired this heightec Hurricane Pro from Jordan Krause in 2022.
This Hurricane Pro is 204 mm. tall, 80 mm. wide, 30 mm. thick, and weighs 624 g.
The shell is a tall irregular shaped stamping made from 2.9 mm. stainless steel sheet metal. The upper portion of the shell supports the pulley assembly. The sheave is a 15 mm. wide plastic U-grooved turning with an outer diameter ranging from 48 mm. in the center to 58 mm at the sides. It rides on an 8 mm. stainless steel axle riveted to the back plate. The sheave has a bearing whose details I cannot see without destroying the device. A 2.9 mm. thick swinging cover plate keeps the rope on the sheave, and a washer and wavy spring washer provide some friction to keep the cover plate from flopping loosely. A closure block riveted to the shell turns to lock the cover plate closed. In the open position, the closure block interferes with cam opening.
There is a 15 mm. carabiner hole above and to the right
of the pulley. The shell also has three quadrilateral-shaped openings
that save some weight, but are primarily decorative.
A 15.4 mm.rope channel is formed in the lower portion of the right side and a smaller cam channel lies opposite on the left. A hole drilled through both sides of the cam channel accepts a 6 mm. rivet. The cam and cam spring are mounted on this rivet. The head of the rivet is on the front of the shell. The pivot is centered 51 mm. from the inside of the rope groove. There is a 5.0 mm. high, 7.9 mm. cam stop pin riveted to the shell.
The cam is a plated skeletonized steel casting. The cam radius, measured from the pivot, increases from 38 to 52 mm. over an angle of 37°, giving a 26° cam angle. The cam has number of small conical teeth, all of which have their axes approximately parallel to the lower surface of the cam. The tooth pattern is (1.2^3)^2(1.2)^2(B). The B stands for a small bar. A spring-loaded manual safety is mounted on an axle riveted to the bottom center of the cam. The normal action of the spring holds the safety against the cam. The safety has a 13 mm. tall, 6 mm. diameter pin mounted on it for the fingers. When the cam is opened, the shell interferes with the safety, thus preventing cam opening. At full open the safety can be released and the spring will hold the tab against the back of the shell, locking the cam open.
The rear of the shell is faintly etched with a strength rating illustration for pulley use (2 kN total - presumably a working load limit), "CE0120," "D43" "Hurricane Pro," "Locking Pulley," "www.heightec.com," "EN 567," "prEN 12841B," "EN 12278," "O," "Ø10.5-12.0," a book-with-an-"i" icon, and "270218 576."
The heightec Hurricane Pro is designed to provide a means to attach a pulley to a fixed line. When used for this purpose, a carabiner in the carabiner hole will interfere with the running rope.
The Hurricane Pro is very well made, but I would rather use a pulley with a metal sheave than a plastic one.

I acquired this heightec Hurricane Pro D43 from Sarah Potter in 2022.
This Hurricane Pro is 200 mm. tall, 71 mm. wide, 31 mm. thick, and weighs 532 g.
The shell is a tall irregular shaped stamping made from 2.9 mm. stainless steel sheet metal. The upper portion of the shell supports the pulley assembly. The sheave is a 15 mm. wide plastic U-grooved turning with an outer diameter ranging from 48 mm. in the center to 58 mm at the sides. It rides on an 8 mm. stainless steel axle riveted to the back plate. The sheave has a bearing whose details I cannot see without destroying the device. A 2.9 mm. thick swinging cover plate keeps the rope on the sheave, and a washer and wavy spring washer provide some friction to keep the cover plate from flopping loosely. A spring-loaded latch locks the cover plate closed.
A 16 mm.rope channel is formed in the lower portion of the right side and a smaller cam channel lies opposite on the left. A hole drilled through both sides of the cam channel accepts a 6 mm. rivet. The cam and cam spring are mounted on this rivet. The head of the rivet is on the front of the shell. The pivot is centered 48 mm. from the inside of the rope groove. There is a 4.7 mm. high, 7.9 mm. cam stop pin riveted to the shell.
The cam is a plated skeletonized steel casting. The cam radius, measured from the pivot, increases from 33 to 53 mm. over an angle of 45°, giving a 31° cam angle. The cam has number of small conical teeth, all of which have their axes approximately parallel to the lower surface of the cam. The tooth pattern is (2)(1.2)^8(B). The B stands for a small bar. A spring-loaded plastic manual safety is mounted on an axle riveted to the bottom center of the cam. The normal action of the spring holds the safety against the cam. When the cam is opened, the shell interferes with the safety, thus preventing cam opening. At full open the safety can be released and the spring will hold the tab against the back of the shell, locking the cam open.
There is an 8 mm. auxiliary hole at the top and a 14 mm. carabiner hole below the cam. The shell also has five openings that save some weight, but are primarily decorative.
The rear of the shell is faintly etched with a book-with-an-"i" icon, "D43" "Hurricane Pro," "Locking Pulley," "heightec," a strength rating illustration for pulley use (2 kN total - presumably a working load limit), "OØ," "10.5 - 12.0mm," "CE0120," "EN 567," "prEN 12841B," "EN 12278,", "201119 1227," and "Patented."
The heightec Hurricane Pro is designed to provide a means to attach a pulley to a fixed line. The Hurricane Pro is very well made, but I would rather use a pulley with a metal sheave than a plastic one.
This version is much lighter than the pervious version. It would be a lot more flexible if the small auxiliary hole was enlarged to serve as a carabiner eye.

I acquired my heightec-PMI Haul Cam from On Rope 1 in 2008.
My heightec-PMI Haul Cam is 202 mm. tall, 84 mm. wide, 31 mm. thick, and weighs 633 g.
The shell is a tall irregular shaped stamping made from 2.9 mm. stainless steel sheet metal. The upper portion of the shell supports the pulley assembly. The sheave is a 15 mm. wide plastic U-grooved turning with an outer diameter ranging from 48 mm. in the center to 58 mm at the sides.

A hole drilled through both sides of the cam channel accepts a 6 mm. rivet. The cam and cam spring are mounted on this rivet. The head of the rivet is on the front of the shell. The pivot is centered 51 mm. from the inside of the rope groove. There is a 5.0 mm. high, 7.9 mm. cam stop pin riveted to the shell.

At full open the safety can be released and the spring will hold the tab against the back of the shell, locking the cam open.
The rear of the shell is etched with "heightec-PMI," "www.heightec.com," "Haulcam D43A," a book-with-an-"i" icon, "OØ," "10.5-13," and"0608 017."
My heightec-PMI Haul Cam D43 is identical to my heightec heightec Hurricane Pro D43, Version A. The difference in the allowable rope diameters is probably due more to historical testing than to actual capability.
The cam is the same as the cam on the heightec-PMI Pulsar D40 and D41A ascenders and the D41A/ D44 Rope Grab/ D44A; the safety is the same as the one on the latter.
The heightec-PMI Haul Cam did not come with any instructions, most likely due to an oversight, because the box contained instructions for the heightec-PMI Powerlock (a stop bobbin) instead. I was able to get a set of instructions for the heightec Rescue Hauler, which is essentially the same device.
