The security enhances if the elevator arrived the biggest promotion
spot, the limit switch can the automatic turnoff power source, the
drive motor stop rotating, automatic protection flowing tubing head
pressure system.

The strong powerful hoisting jack along with the use flowing tubing
head pressure installment integration import end product, enables to
maintain stable and the balanced product quality.

Low noise, low vibration in column/On the steel wire guide rail has used the high-level engineering
plastics, greatly reduced the noise, the attrition and the mechanical
vibrations.

The gear nipped the suitable bracket fixing device to use has been
able to prevent the bracket suddenly revolved in the service work the
safety device.

Inside and outside suspends the arm to suspend the arm the spiral nail
hole Line and enclose to use the dual thread structure, therefore can replace,
the about crevice is small. Because makes with the rubber resin wears
slightly.

Uses the epoch-making oil pressuring cylinder oil pressuring cylinder
the low noise design, increased the durability.

About the solution the oil pressuring cylinder balanced synchronized
pressure pipe is located the installment the central committee, the
balanced assignment, has solved about the oil pressuring cylinder
pressure difference, further enhanced the security.

Does not need Lift and rise the drop function relieves locking, does not need
upheaval to drop again, but is the direct drop function, causes the
operation to be more convenient.

Time the safe stopping device drop safe stopping device (locking),
after the dump, can protect the flowing tubing head pressure
installment, enables you a more convenient security to carry on the
service work.

The oil pressuring cylinder oil leak percentage hundred eliminations
oils pressuring cylinder connecting rod only received stretches the
strength the design, the oil pressuring cylinder uses the double seal,
the percentage hundred places eliminated the oil leak possibility.

The column column nearly does not receive the torsion, only receives
is vertical the load the design, its rigidity and security
outstanding; The powder spurts spreads processing enable it to have
the beautiful semblance, thus enhanced the product scale.
