The Rock Mills Manhole Systems are ingenious and increase safety.

In today's world, there is an ever-increasing need for safety and security.

Government agencies, utilities, municipalities... everyone's liability will be significantly reduced with the use of the Rock Mills LIFTER and LOCKdown locking systems.

The Rock Mills LIFTER system provides a safe and efficient method for removing and replacing manhole covers.

Cost is the bottom line, and when you consider the injury compensation that affects both the employer and the employee, The Rock Mills LIFTER is well worth the investment!

Using the camera and monitor as a guide, the magnet is positioned over the manhole cover. At the touch of a wireless remote, the magnet is lowered onto the cover, then activated. The cover may then be raised and moved to any location.

The Rock Mills LOCKdown system keeps manhole covers down until you want them up.

In today's litigious society, you simply cannot afford to have manhole covers that others can remove. The Rock Mills manhole cover LOCKdown system is a no-brainer investment!

With the Rock Mills LOCKdown system, there's no way others can remove your municipalities manhole covers.

Options:

• Complete cover with locking mechanism
• Locking mechanism only, to adapt to existing covers

The LIFTER is the opener, or "key", to the LOCKdown manhole cover. With a simple addition to the magnet, The Lifter is used to release the locking mechanism. With The Lifter's magnet activated and the locking mechanism retracted, the cover can be removed with ease.

Optional Swing Arm Attachment

The optional swing arm attachment for The LIFTER can be used on the front or the rear, or wherever a 2" reciver can be mounted on jet trucks or camera trucks. This attachment allows the operator to position the vehicle so that the jet hose or camera is positioned over the manhole cover, and The LIFTER can be swung out of the way.
