Detailed Answer
Shipyards have lots of high-altitude work (hull blocks, gantry cranes), so to prevent remotes falling: 1. Lanyard/shoulder strap (mandatory wear); 2. Wrist strap (backup); 3. Anti-slip housing; 4. Drop test (1m); 5. Fixed storage spots for remotes during high-altitude work. The LDER LD series comes with lanyard + anti-slip as standard; XINGJIA likewise.
| Lanyard | Mandatory wear |
| Anti-slip | Housing texture |
| Test | 1m drop |
Note:Remotes must be lanyarded during high-altitude work — double safety.
