Description

MANUAL RELEASE OF HOIST BRAKE:

  • The brake release device permits the hoist brake to be released manually and thus the load to be lowered during a power cut. As an option, every hoist can be equipped with this supplementary equipment to the standard brake.

ROPE DRUM BRAKE:

  • Redundant brake system provides increased safety. Intercept and holding brake, prevents the load falling even if the gear should break. Control is effected with a centrifugal switch or safety PLC.

FREQUENCY INVERTERS FOR “LIFTING”:

  • Smooth starting and braking characteristics. Load swing greatly reduced. Fast, precise positioning of the load, corrective switching operations rarely necessary. The reduced dynamic load means a longer service life for hoist motor and gear and reduces stress on the whole system.. ESR function (Extended Speed Range) for higher hoisting speeds with partial load. Worldwide approvals for all frequency inverters. Certified in compliance with DIN ISO 9001.

FREQUENCY INVERTERS FOR “CROSS/LONG TRAVEL”:

  • Simple to install, parametrise and operate. Standard speed range 1:10, up to 1:30 as an option. SPS compatible to super-ordinate systems (optional). All internationally customary mains voltages are available. Also available in design for installing in panel box.

TWIN DRIVE CONCEPT:

  • Prevents sagging of the load even when the gearbox fails. Permanent brake, drive and load monitoring. Two synchronously controlled hoist motors and brakes. Two manually releasable brakes for emergency lowering. Robust, completely encapsulated system. Service and safety brake of identical design. Up to 60 % higher load capacities when transporting non-molten metals.

SIGNAL TRANSMITTERS:

  • Visual and acoustic signal transmitters such as horn and flashing light can be mounted on travel carriages. The signal transmitters can be activated by a button on the control pendant.

LOAD DISPLAY:

  • SLD four-digit 7-segment load display (Stahl Load Display), large format, luminous red, available with various interfaces including CAN. Choice of 60, 100 or 150 mm digit height. No additional sensor is required as the standard load sensor is used.

SMC MULTICONTROLLER:

  • Continuous load monitoring by overload cut-off even if hoist is at a standstill. Overload protection with ALC automatic load control. Load spectrum memory for load-related operating time summation. Monitoring of the motor temperature of the hoist motor and travel motor. Operating data registration, e.g. operating hours, load spectrum, motor switching operations and load cycles. Data exchange with PC possible.

EMERGENCY HOIST LIMIT SWITCH:

  • In standard version, the hoist is equipped with a gear limit switch for top and bottom hook position and an operational limit switch for top hook position. As an option, up to eight switching elements can be fitted to the switch. This permits for example further stopping positions and operational limiting in bottom hook position.
