Directional lock

Directional lock is an accessory that can be fitted to the top plate of a swivel bracket by using the same fixing bolts to the trolley. When engaged, it locks the bracket rotation in a precise direction, turning it into a fixed castor. The device is used on at least two of the four swivel brackets fitted on a trolley, thus allowing the simultaneous towing of more trolleys.

Directional lock for electrowelded brackets

Directional lock for EE MHD - EEG MHD - EE HD brackets (Item nr 401216-401217)

Directional lock

Designed for assembly on the top plate's short side, it consists of galvanised steel parts and is suitable for trolleys subject to mechanical towing at speeds up to 16 km/h on indoor and outdoor floors (asphalt, cement).

Easy to engage by self-clicking into position.

Specifications:

  • it is fitted to the top plate of a castor by using the same fixing bolts which secure the castor to the trolley
  • it can be fitted with EE MHD and EE HD electrowelded castors, to EEG MHD twin electrowelded castors (only on diam. 100-125 mm), to EES MHD sprung-loaded electrowelded castors (please see the table on the following page for details)
  • it can be fitted to Tellure Rôta brackets which have the appropriate slot

The directional lock for electrowelded castors can be assembled with brackets with appropriate slots. To order castors configured with slots, please add the above specified suffix to the part number of the complete castor.

Example: to order the part number 628314 with 2 slots, it is necessary to show the part number 628314B2. Sprung electrowelded castors EES MHD are an exception, since they are realised in standard version with 2 slots.

SCHEME OF ASSEMBLY
1
STEP 1 PREPARATION
Four M10 bolts and four M10 nuts are required for directional lock 401216 (MHD type); M14 bolts and nuts are instead required for directional lock 401217 (HD type).
• Self-locking nuts and 8.8 bolt strength are recommended.
• The length of the bolts depends on the trolley characteristics (usually longer than 40 mm).
2
STEP 2 INSTALLATION
The directional lock and the castor have to be positioned and subsequently fastened as per the adjacent picture.
• The bolt has to protrude through the nut by at least 3 threads.
3
STEP 3 TIGHTENING
The proper tightening of the bolts has to be verified by a torque wrench.
• The recommended tightening torque of a self-locking nut is 25 Nm for dir. lock 401216 (bolts M10) and 60 Nm for dir. lock 401217 (bolts M14).

STEP 4 FINAL CHECK
Make sure that the directional lock engages properly into the slots of the bracket and that the castors are aligned to the direction of movement of the trolley once the directional lock is applied.
