The ability to lock a caster converts a swivel caster into a rigid caster. Locking a caster wheel into a fixed position is for the purpose of transporting the caster (in most cases a cart with casters attached) some distance and being able to steer the caster to a final desired location. Once the caster is near the exact destination, the caster will be unlocked so that the cart can be moved in all directions to locate it. The locking caster provides flexibility for ease of movement in a tight area and ease of transportation when traveling a longer distance.
Heavy duty locking casters can be built with a locking mechanism at the time it is manufactured, or you may request a field-installed brake for a caster that has previously been purchased. We strongly suggest that if you want the ability to lock casters in your application that locks built into the original design are much more desirable and will have a greater usable life cycle than locks applied after the fact.
Locks are also often considered a safety option as a cart moved with two locked casters (rigids) and two swivels is much easier to handle than a cart that has four swivels. It will take a lot of force to keep a cart with 4 swivel casters on track, while using two locking swivel casters seldom leads to injuries while attempting to control a loaded cart.
Passive Swivel Lock
The passive swivel lock is used when full mobility of a unit is needed. The swivel lock plunger engages a detent and locks the caster for straight line movement. When side thrust is applied, the swivel unlocks providing maximum maneuverability of the unit. This swivel lock is NOT RECOMMENDED for towed applications.
Foot Actuated Swivel Lock
The foot operated swivel locking mechanism is the same as the standard swivel lock. To engage or disengage the lock, there is a pedal that can be operated by foot to improve ergonomics and speed of locking/unlocking a swivel caster.
Heavy-Duty Demountable Swivel Lock
Heavy-duty demountable swivel lock is a field-installed option available for the 80s and 90s Series casters.
Heavy Duty Swivel Lock
The heavy duty swivel lock provides a longer, more accessible handle made from machined steel.
Demountable Swivel Lock
The demountable swivel lock is a field-installed option available up to the 71 Series. Other series can be ordered with demountable swivel locks where damage to the swivel may occur.
Vertical Mounted Swivel Lock
The vertical mounted swivel lock is mounted out of the way, under the yoke base of the caster. Used mostly in heavy duty applications, this swivel lock provides a more secure locking feature
