Doughty T58100: clamp, fixture attachment and secondary retention
Prepare an inquiry for a Lightweight Half Coupler with an identified fixture and tube.
Identification and application
T58100 is the polished Lightweight Half Coupler; T58101 has a black finish. It is a different reference from Super Lightweight. Fixing hardware and other accessories need to be specified separately.
References for your inquiry
- Tube and fixing
- 48–51 mm diameter; provision for M10 or M12 fixings per the data sheet. Identify the fixture attachment.
- Manual
- Lightweight Half Couplers & Hook Clamps, Revision 13. Distinguishes lifting and static WLL.
Prepare the information
- Record fixture model and weight with accessories, and its approved attachment point.
- Identify tube diameter, material, finish and support, plus orientation and load direction.
- Gather the clamp, fixing hardware and secondary-retention references required for the installation. The installation supervisor must review them and arrange inspection before use.
Questions and alternatives
Is the clamp rating enough to verify the entire suspension?
No. Read the product sheet together with manual Revision 13, which distinguishes lifting and static loads. The installation supervisor must also review the tube, its support, the fixture connection and the load direction to determine which rating applies to the assembly.
Is M10 or M12 enough to order a bolt?
You also need the bolt length and grade, the nut type and the fit with the fixture. Confirm the documented fixture and clamp attachments; the fixing must not contact the tube when tightened. Do not use the tightening torque from another connection. For equipment that moves or is suspended over areas with people, Revision 13 requires an M12 self-locking nut instead of the standard nut or wingnut. This requirement is part of the assembly review. The fixture’s secondary retention is specified separately.
Can it be mounted sideways to save space?
Loads parallel to the tube and arrangements creating torsion have specific limitations in the manual. Record orientation and distance to the load point for competent review. Straight-pull WLL does not authorize another direction.
Does the clamp replace the fixture’s safety bond?
No. The fixture’s secondary retention is specified separately, using the manufacturer’s intended attachment point and the system required for the installation. We can help gather the references for both components. Select retention equipment and its attachment point from documented specifications.
What if it slips or is damaged?
Coordinate removal of the load and isolation of the area with the installation supervisor. Do not test by increasing torque with the fixture suspended. Record the part reference and its visible condition for inspection. Damaged parts remain out of service, and repairs require authorized personnel.
What alternatives can we quote?
We can assess a documented clamp and fixing for the tube and fixture, another equipment position or a different identified support. A proposal can separate hardware, secondary retention and preparation or installation. Start with photos and approximate measurements; the installation supervisor must review the system before loading.
