Please note the wheels are now Green and not White The strongest wheel skate money can buy! A massive 1800kg load capacity per skate means these skates will handle the largest and heaviest of vehicles including loaded vans and small trucks. These skates are designed for heavy use in the recovery industry and are virtually indestructible. Simply jack the damaged vehicle up and lower the wheel (damaged or flat tyres no problem) into the skate, the vehicle is then mobile. When using two pairs, the vehicle can be moved or rotated in any direction. Stop wasting time and effort dragging disabled vehicles around the workshop! Can be used for winching vehicles up onto recovery truck slide beds.
