ELECTRO-HYDRAULIC DOCK-LEVELLER mod. KRB (A)

KRB dock-levellers are composed by a steel frame, made with welded profiles, and the upper plate and the lip by an anti skid steel sheet. Reinforcing welded tubes under plate with section mm. 150 x 30 x 3, placed every 30 mm. Thickness of upper plate mm. 6 + mm. 2 of anti skid ribs Thickness of rotative flap: mm. 14 + bottom reinforcing welded plate, mm 120 x thickness 10 Diameter of hinges: internal mm. 35 – external mm. 55 Hinge between main plate and lip is continuous on the full width of the ramp. Hydraulic movement of lifting and opening of the lip is by means of single effect chromed pistons, whose electric command is under the dock-leveller. Lifting cylinder diam. mm. 50 (core) Lip rotation cylinder diam. mm. 40 (core) It is possible to stop and secure maintenance operations by blocking the dock leveller using a special galvanized rod. Security block: in case of accidental moving of the truck, the dock leveller will be blocked with a short stroke ( according to the applied weight). Every dock-leveller is equipped with lateral security galvanized plates for feet protection. Once the edge is positioned on the loading part of the truck, this edge follows movements of it during loading operations, with a lateral torsion tolerance of 100 mm. Every dock-leveller is coloured by blue painting RAL 5003 Electric commands in accordance to CEI IP 55 rules. Power supply: 380 V 3phases Control panel with up/down/stop, security stop, main power switch buttons; “dead man” operating system; low tension 24 V d.c. commands. Electrical engine power Kw 0.55 - IP 55 Working pressure approx. 120 bar Concentrated load on fork-lift allowed: kg. 6.000.max. Uniformly distributed load: kg. 9.000. max. All dock levellers are manufactured according to CE rules, and fully satisfy EN 1396 norms.

ELECTRO HYDRAULIC DOCK-LEVELERS WITH TELESCOPIC LIP MOD. KRT

General Data

KRT dock-levelers are made with strong profiled steel, and flat part is made by an anti skid steel sheet. Hydraulic movement of lifting and opening of the edge is by means of 3 chromed pistons, whose electric command is under the dock-leveler. Length of telescopic lip: mm 500 / mm 1.00 0(according to the model) Security block: in case of accidental departure of the truck, the dock leveler will be blocked in a short stroke (according to the applied weight) Every dock-leveler is equipped with lateral security plates for feet protection Once the edge is positioned on the loading part of the truck, this edge follows movements of it during loading operations, with a lateral torsion tolerance of 100 mm. It is possible to stop and secure maintenance operations blocking the dock leveler by a special rod. Every dock-leveler is coloured by brown RAL 7003 (old versions) Blue RAL 5003 (new versions. Power supply: 380 V 3phases Electric commands in accordance to CEI IP 55 rules. Control panel with up/down/stop, security stop, main power switch buttons; “dead man” operating system; low tension 24 V d.c. commands. Electrical engine power Kw 0.75 - IP 55 Concentrated load on fork-lift allowed: kg. 6.000. Uniformly distributed load: kg. 9.000. All KRT ramps have CEE certification.
