Rack and pinion jacks for removing heavy maintenance covers

Supplier News
Motion Technologies now offers the recently redesigned ZWW wall mounted rack and pinion jacks from Pfaff (Germany) in the 1.5 tonne to 10 tonne range.
   
The rack and pinion jacks are designed to safely remove heavy maintenance covers safely in mining applications.
   
The products are available with spur gear or worm gear options.        
   
As the covers are rigidly attached to the end of the rack, and the crank handle has a ratchet, maintenance operators can apply a light pre-tension to the cover prior to unseating the seals on the cover. The cover can then be safely wound out of the way.
   
These jacks are designed for Sluice gate applications and are said to be suited to all outdoor environments. Stroke is around 550-800mm depending on the model.
