SELECT RIGHT WHEELS


up_images/32select_whills.png
LOAD:
 
The larger the diameter greater the load that can be carried. Rough surfaces or high impact loads halve the capacity. Roller bearings permit higher wheel loads for hand pushing due lower friction.
 
SURFACE:
 
The larger a wheel the easier it rolls on all surfaces. On smooth surfaces hard treads roll easiest, but consider potential floor damage on rough or soft surface where soft treads roll easiest.
 
ENVIROMENT: Wet or corrosive – specify type of chemicals.
 
THREADS, LINT or FLUFF: Specify threads guards
 
HEAT OR VACUUM:
 
Use Phenorex, Reinforced Nylon or Cast Iron. Specify temperature so that special grease can be used.
 
SWIVEL OR RIGID FITTING:
 
How it will be fitted to the trolley. If appropriate - choose the attachment required(if available ). Springs take impact strain off trolley, protect loads, provide greater comfort. Swivel & Wheel Locks make trolley rigid & stable.
 
DIRECTIONAL LOCK:
 
Allows for good tracking when locked and maximum manoeuverability in confined spaces when unlocked.
 
FITTING:
 
If fixed and Swivel Castors are to be used together, have the fixed castors at the front, the trolleys turns more easily. Never try to get the unevenness out of a warped trolley by half inserting fittings. You can get upto 8 mm of adjustment with washers, - but do not let it float. Tighten tubular fittings firmly. But do not over-tighten.
