Dunlop Mastclimbers are engineered with the maximum available safety rating. No other mastclimber contains the same high level of safety engineering.
Dunlop Mastclimbers are recognized as the industry leader when it comes to safety. For that reason, several government agencies including the New York Housing Authority and the City of Philadelphia have certified the use of Dunlop Mastclimbers as the safest means and methods to fulfill the scaffolding needs of their projects.
Dunlop Mastclimbers are inherently safer than pipe scaffolding or swing staging, just by nature of their technology and structure. And in comparison to other mastclimbers, Dunlop Mastclimbers are the industry leader. No other mastclimber can claim the same high level of safety engineering.
The top limit switch is designed to prevent a Dunlop Mastclimber from climbing above the top of the last mast. The spring-loaded switch is attached to the uppermost part of the main platform deck around the tower mast cage. If the spring-loaded roller arm runs over the top of the mast, the switch will automatically cut power to the upward power cycle.
Safety Features of a Dunlop Mastclimber: |
The bottom limit switch is designed to prevent a Dunlop Mastclimber from crashing into grade level. It is attached to the lowermost portion of the main platform deck around the tower mast cage. If the spring-loaded roller arm contacts the stop-plates positioned on the base of the tower, the switch will automatically cut power to the downward power cycle. The bottom limit switch can be set to stop the platform at a desired height above a sidewalk shed or cribbing, for example.
The phase monitor insures the correct rotation of the three phase electric current that powers the Dunlop Mastclimber. If the current is correctly and safely flowing, then the phase monitor releases power to the pendant control for the user to safely operate the Dunlop Mastclimber.
Each Dunlop Mastclimber is fitted with a pendant control to operate its movement. The pendant control is usable by any trade personnel so long as he or she is trained in the safe operation of a Dunlop Mastclimber.
A Dunlop Mastclimber is powered by two independent motors. Each motor is equipped with an electromagnetic brake which is strong enough tot hold the entire load should the other brake fail for any reason.
The pendant control has a large red emergency stop button that allows the operator to immediately cut all power to the Dunlop Mastclimber.
Pioneered by Dunlop Mastclimbers, this important safety feature is set inside the electric control panel. The safety overload sensor is set to calculate the correct weight and correct weight distribution allowed on the Dunlop Mastclimber. If for any reason, a Dunlop Mastclimber is overloaded or if the weight is improperly balanced, the overload sensor will automatically shut down the power. This trip switch will then automatically reset once the excess load is removed from the platform.
In the event of a power failure, a Dunlop Mastclimber can be safely lowered down to grade level using a manual brake release. The manual brake release causes the Dunlop Mastclimber to descend at the same controlled rate as when the power was on. The manual brake release is located on top of each motor and can be accessed through a trap door on the platform deck.
A Dunlop Mastclimber is fitted with an audible alarm that sends whenever the unit is in motion. The alarm alerts personnel that the Dunlop Mastclimber is on the move.
