Safe Operation Rules Only those who are familiar with the safety operation rules and
maintenance requirements of this type of tension machine and have
received professional training are allowed to operate this tension
machine. (1) The two operators of the stretcher must communicate with each
other to avoid serious accidents caused by the traction of the
stretcher before it is in the tension release condition. (2) When the tension machine is working, the operator is forbidden
to give up control or leave the tension machine. (3) When operating the tension machine, the control handle and the
adjustment pressure should be smooth, and excessive and too fast
force should be avoided to avoid brutal operation. Special
attention should be paid to it is forbidden to greatly reduce or
increase the tension when tension is laid out, which will cause the
wire to fluctuate too much and damage the span frame and other
buildings. (4) It is strictly forbidden to put the brake handle in the brake
position during tension discharge, otherwise it will lead to
serious accidents. (5) It is absolutely forbidden to use reverse pull function as
brake. (6) During tension discharge, each meter should be continuously
observed, and the hydraulic oil temperature should not exceed 85℃;
Oil filling pressure (back pressure) shall not be lower than
1.8mpa, shall not be higher than 2.5mpa; The brake oil pressure
shall not be lower than 3.5mpa and shall not be higher than 6Mpa.
Otherwise, stop the machine for inspection immediately. (7) The pressure of the safety valve has been pre-adjusted, so do
not adjust it randomly. If the tension machine does not work due to
unauthorized adjustment of safety valve, it will bring you a lot of
trouble and loss. (9) The fastening condition of fixing bolts of nylon lining block
should be checked regularly to prevent unnecessary losses caused by
loosening and wear of wires caused by fixing bolts. (10) When the tension machine runs, keep the engine running at
medium speed to maintain high power and prevent the hydraulic oil
from overheating. (11) When tension is laid out, the "tension wheel direction
control" knob should be in the middle position, and it is strictly
prohibited to move at will, otherwise it is easy to cause serious
accidents such as line running. (12) Under the driving condition, the driving direction of the
tension machine must be changed after the tension wheel stops
completely before the driving direction can be changed. |
