Safety is the top priority in any vertical pull, as gravity introduces significant risks. A professional vertical pulling machine must have these key safety features:

• Fail-Safe Braking System: This is non-negotiable. The machine must have an automatic, mechanical brake that engages instantly in case of a power loss or hydraulic failure. This prevents the cable from slipping or free-falling, which could cause catastrophic damage or injury.

• Tension Overload Protection: The machine's control system should allow the operator to preset a maximum tension limit. If the pulling force exceeds this limit, the machine will automatically stop, preventing damage to the cable's internal conductors and insulation.

• Precision Speed Control: A variable speed control allows the operator to perform the pull at a slow, constant rate, which is essential for managing the cable's weight and avoiding sudden surges in tension.

• Data Logging: Modern vertical pullers often include a data logger that records the tension and speed throughout the pull. This provides a permanent record for quality control and can be used to prove that the installation was performed within the cable manufacturer's specifications.
