side pull: the portion of the hoist pull acting horizontally when the hoist lines are not tensioned vertically.

sill beam: horizontal structural members that connect the lower ends of two or more legs of a container-handling crane.

siap block: a sacrificial protective device or guard to pro- ted the wire rope or other parts of the crane from rope contact.

s;zn: the horizontal distance, center to center, between runway rails or tire centers.

spreader: a fixed or telescoping frame attached to the headblock that is used for lifting containers (see Fig. 3). siop, runway or trollei: a device to limit travel. This device normally is attached to a fixed structure and normally does not have

energy-absorbing ability,

switch: a device for making, breaking. or changing the connections in an electric, hydraulic, or pneumatic circuit.

switch, emergency slop: a manually actuated switch to disconnect power independently of the regular operating controls.

switch, until: a device that is actuated by the motion of a part of a power-driven machine or equipment to alter or disconnect the electric, hydraulic, or pneumatic circuit associated with the machine or equipment.

switch, main (crane disconnect): a switch on the crane controlling the main power supply

switch, master: a switch that controls the operation of contactors, relays, or other remotely operated devices.

switch, spring return: a switch that, when released, will return automatically to a neutral (off) position.

torque proving: a feature that ensures sufficient motor torque is applied to the motor shaft prior to release of the brake(s) and

the start of drive operation.

trolley: the unit that travels on the trolley rails and supports the load and lifting apparatus.

truck: an assembly that includes a pivot, frame, axle(s), and wheels on which a crane rides on rails.
