A set of 4 yellow machinery skate dollies designed for moving heavy equipment up to 13,200 pounds. Each dolly features 4 PU anti-slip rollers (8x7 cm) that provide strong grip and shock absorption with quiet operation. Constructed from carbon steel with PU surface treatment and plastic spraying. Each unit has 2 mounting handles. The steering handle transfers load weight directly to rollers, requiring less force to start moving. Maximum bearing capacity is 6 tons (13,200 lbs) with a normal load of 4 tons.
