■ Hydraulic gear motor
■ Spring-applied, pressure-released multi-disc
brake with static and dynamic functions
■ During hoisting, the hydraulic motor drives
direct into the planetary reductions without
affecting the brake assembly. When forward
rotation is stopped, an over-running clutch will
lock and the multi-disc brake will positively hold
the maximum load.
■ During lowering, the brake is released
automatically and then modulated for the
desired lowering speed by a single control
lever.
■ A counter-balance valve is not required for
smooth and positive “Down” control.规格
